Please read this owner's manual carefully before installing this amplifier. 2. Disconnect the battery ground terminal prior to making any electrical connections. 3. Check for any hazards or obstructions such as gas tanks, fuel or brake lines, and wiring harnesses before mounting the amplifier. 4. Pick a mounting location that will provide adequate access and ventilation and protect the amplifier from heat, moisture, and dirt. 5. Avoid sharp metal areas when routing cables to the amplifier, and run RCA cables away from the power cables and other potentially noisy car harnesses. 6. The amplifier should be grounded with a short, heavy gauge wire connected directly to the car at a bare metal surface, preferably scraped body sheet metal. Do not use factory ground locations, seat bolts, or brackets that are spot welded. 7. Always fuse your power connection within eight to ten inches of the battery terminal. Use a fuse or circuit breaker rated slightly more than the on-board fuse(s) of the amplifier(s). The gauge of power wire used should take into account the total current draw of the system, and the length of wire used. IASCA and other auto sound competition organizations have charts available for this; you can also find a chart in the MECP study guide. Minimum wire gauge recommendations for the individual amplifiers are listed on the specification page. Always use the same gauge wire for the amplifier ground that you use for the power wire. Be sure to examine the battery ground cable of the vehicle, and if necessary, upgrade it by adding an additional ground wire that is the same gauge as the amplifier's power wire. Remember, the amplifier can only deliver its rated output when it is not current limited by the power and ground supply wires. 8. This amplifier is designed to drive a speaker load that measures from 28 ohms (sub ch 1-4 ohms). Keep in mind that heat is the long-term enemy of automotive electronics 6 © 2003 Directed Electronics, Inc and the lower your speaker load, the more heat is generated. For low impedance speaker applications or restricted ventilation installations, an external cooling fan may be advisable. 9. Battery and ground connections to the vehicle should be made with crimped ring terminals of the appropriate size (surface area is what counts); soldering the terminals after crimping is also recommended. 10. Due to the high-frequency MOSFET switching power supply, filtering the power cable is not generally required (remember that the amp can't deliver full output if the power supply is restricted). Proper grounding of the signal source is mandatory for the amplifier to reach its performance peak. If the RCA inputs are not grounded adequately via the signal source, electrical noise from the vehicle may be picked up in the system. © 2003 Directed Electronics, Inc 7 FRONT PANEL CONNECTIONS/STATUS LED 1. RCA Input Jacks - Accepts line level outputs from head units or signal processors between 150mV and 8 volts. 2. RCA Sub Input Jacks - Accepts line level outputs from head units or signal processors between 150mV and 8 volts for the subwoofer section of the amplifier. 3. RCA Output Jacks - These pass through RCA jacks can be used to send a signal to a second amplifier. It is the summed stereo output of the one through four channel inputs of the amplifier. 4. RCA Sync Out Jack - This RCA jack sends a synced, or in-phase, gain matched signal to a 750d slave amplifier when connected in the Parallel Synced Gain combination. (Refer to the Combined Amplifiers section of this guide.) 5. RCA Bridge Output Jack - This output sends an out-of-phase signal to a 750d slave amplifier when connected in the External Synced Bridged combination. (Refer to the Combined Amplifiers section of this guide.) 6. Status LEDs - The Power LED will light GREEN to indicate the amplifier is on and operating normally. The GREEN LED will turn off and the Protection LED will light RED when the amplifier has shut itself down due to speaker short circuit, DC offset or overheating. 7. Remote Sub Level Control - Controls the subwoofer amplifier gain controls from a remote location for ease of adjustment during listening. Warning: DO NOT connect a level control knob from other manufacturers to the Remote Sub Level Control of any Directed amplifier. Even though the connectors fit properly, the control knob and connector pin positions may be different and the amplifier will be damaged.

Input Gain Adjustment - Controls amplifier sensitivity and is used to match the input level of the amplifier to the output level of the signal source. 2. Crossover Selection Switch Controls the type of filter for the onboard active crossovers. FLAT does not attenuate any frequencies and is for full-range speaker systems. HPF attenuates low frequencies and is used for mid-range speakers and tweeters. LPF attenuates high frequencies and is used for subwoofers speakers. 3. Crossover Frequency Adjustment Adjusts the crossover point for the on-board active crossovers. 4. Sub Phase Switch - Changes the phase of the subwoofer speaker output by 180 degrees 5. Bass EQ Switch - Adds 8db of additional boost to the subwoofer output when active. 6. Subsonic Frequency Switch - Sets the cutoff point for subsonic frequencies at 30 Hz. Frequencies below will be attenuated by 24db per octave. 7. Sub Input Switch - Controls where the subwoofer section of the amplifier gets its signal. If the SUB INPUT switch is in the ON position the subwoofer section of the amplifier will get its signal internally summed from the channels one through four RCA jacks, and the SUB RCA jacks do not need input. If in the OFF position the SUB RCA jacks must have input. 8. Input Parallel Switch - Controls the input signal to the indicated channels. If the 3+4 switch is ON, channels three and four will derive their signal from channels one and two RCA jacks and no input is needed. If the 3+4 switch is OFF, channels three and four RCA jacks must have input. 10 © 2003 Directed Electronics, Inc FIGURE 3--AMPLIFIER CONTROLS 1200/5 TOP 4 5 6 PHASE 0 180 BASS EQ OFF ON SUBSONIC OFF ON FREQ FREQ FREQ 3 50Hz 500Hz 50Hz 500Hz 30Hz 250Hz 2 1 MIN 1+2 GAIN LPF HPF FLAT 3+4 GAIN LPF HPF FLAT SUB GAIN MAX MIN MAX MIN MAX OFF 3+4 INPUT ON OFF SUB INPUT ON 7 8 TOP PANEL FEATURES Control Panel Cover Remove/Install The gain and filter controls are located under a control panel cover on top of the amplifier.

They are the Parallel Synced Gain and External Synced Bridged combinations. NOTE: The Directed 1200/5 is always the master amplifier in these combinations. External Synced Bridged The External Synced Bridged combination includes a master amplifier and a slave amplifier. In this master/slave combination the master amplifier's pre-amp controls remain active and the slave amplifier's pre-amp is bypassed. This allows the master amplifier to control gain, filter, and sub-level on both amplifiers. This combination allows the amplifiers to drive common subwoofer loads while being synced together via an out-ofphase audio pre-amp signal from the master amplifier. In this wiring configuration the master amplifier sends the positive signal to the speaker while the slave amplifier sends the negative signal, making an externally bridged speaker combination. (Refer to External Synced Bridged section of this guide for amplifier and speaker connection diagrams.) Combined Amplifiers Gain and Filter Settings Parallel Synced Gain The Parallel Synced Gain combination includes a master amplifier and a slave amplifier. In this master/slave combination the master amplifier's pre-amp controls remain active and the slave amplifier's pre-amp is bypassed. This allows the master amplifier to control gain, filter, and sub-level on both amplifiers. The Parallel Synced Gain combination allows the amplifiers to drive their own separate subwoofer(s) while being synced together via an in-phase audio pre-amp signal from the master amplifier. Woofer wiring connections to the amplifier subwoofer outputs in this combination should be standard in-phase configurations, creating a parallel speaker combination. (Refer to Parallel Synced Gain section of this guide for amplifier and speaker connection diagrams.) Set the Subsonic, EQ, and other filter settings on the master amplifier to the positions that achieve the best sound quality. Follow the adjustment guidelines discussed in the Crossover and Gain Adjustment section of this guide. © 2003 Directed Electronics, Inc 13 PARALLEL SYNCED GAIN CONNECTIONS/SETTINGS 1. Input/Output Signal - Connect these RCA jacks as described in the Front Panel Connections/Controls section of this guide. 2. Remote Sub Level Control - Connect the Remote Sub Level control to the 1200/5 only. The 1200/5 control panel subwoofer adjustments are used first to set the overall gain for all synced amplifiers, then the Remote Sub Level control can adjust the gain of all synced amplifiers by adjusting its control knob. 3. Signal Connection - Connect an RCA cable between the SYNC OUT RCA jack of the 1200/5 and the SLAVE IN RCA jack of the slaved 750d as shown in Figure 5. 4. Slave/Master Switch - Set the slave/master switch of the 750d to the slave position. This will put the I/O RCA jack in the SLAVE IN mode so it will accept the audio signal from the 1200/5's sync out RCA jack. 5. Subwoofer Speaker Connection - In this amplifier combination each amplifier must drive its own separate subwoofer(s). Connect the speaker terminals of each amplifier to any combination of one or more subwoofers that results in nominal impedance between 1 and 4 ohms. Make sure that each amplifier sees the same speaker impedance. 14 © 2003 Directed Electronics, Inc FIGURE 5--PARALLEL SYNC GAINED 750d/1200/5 Master (1200/5) 1 1+2 3+4 SUB 1-4 OUT SUB OUT Do Not Use SLAVE SYNC OUT POWER MASTER R L BRIDGE OUT REMOTE PROTECTION 2 Slave (750d) MIN MAX SUB LEVEL 3 INPUT I/O SLAVE IN SYNC OUT SLAVE MASTER R L BRIDGE OUT REMOTE Do Not Use 4 Do Not Use Speaker Wiring (top view) SUBWOOFER MASTER 1200/5 SUB + - + SLAVE 750D - 5 + + + NOTE: The dual + and -- sub-out terminals of the 750d are paralleled internally and the combined load impedance should be taken into consideration when connecting multiple subwoofers. © 2003 Directed Electronics, Inc 15 EXTERNAL SYNCED BRIDGED CONNECTIONS/SETTINGS 1.

Remote Sub Level Control - Connect the Remote Sub Level control to the 1200/5 only. The 1200/5 control panel subwoofer adjustments are used first to set the overall gain for all synced amplifiers, then the Remote Sub Level control can adjust the gain of all synced amplifiers by adjusting its control knob. 3. Signal Connection - Connect an RCA cable between the BRIDGE OUT jack of the 1200/5 and the SLAVE IN jack of the slaved 750d as shown in Figure 6. 4. Slave/Master Switch - Set the slave/master switch of the 750d to the slave position. This will put the I/O RCA jack in the SLAVE IN mode so it will accept the audio signal from the 1200/5's sync out RCA jack. NOTE: There is only one master when syncing amplifiers. 5. Subwoofer Speaker Connection - In this amplifier combination the Subwoofer output terminals of both amplifiers drive a common subwoofer load. Use the speaker connection diagram in Figure 6 when connecting the subwoofers to the amplifiers. Connect the amplifiers speaker terminals to any combination of one or more subwoofers that results in a nominal impedance between 2 and 4 ohms. DO NOT connect loads of less than 2 ohms when connecting to amplifiers in the External Synced Bridged combination. WARNING: Two wires of 12AWG minimum must be connected between the negative sub out terminals of the master and slave amplifiers. 16 © 2003 Directed Electronics, Inc FIGURE 6--EXTERNAL SYNC BRIDGED 600d/1100d5 Master (1200/5) 1 1+2 3+4 SUB 1-4 OUT Do Not Use SUB OUT SYNC OUT POWER SLAVE MASTER R L BRIDGE OUT REMOTE PROTECTION 2 Slave (750d) MIN MAX SUB LEVEL 3 INPUT I/O SLAVE IN SYNC OUT SLAVE MASTER R L BRIDGE OUT REMOTE Do Not Use 4 Do Not Use Speaker Wiring (top view) MASTER 1200/5 SUB 12 gauge + SLAVE 750D 5 + 12 gauge + + NOTE: The dual + and -- sub-out terminals of the 750d are paralleled internally and the combined load impedance should be taken into consideration when connecting multiple subwoofers. © 2003 Directed Electronics, Inc 17 CROSSOVER SETTINGS AND GAIN ADJUSTMENT Your Directed Audio power amplifier needs to be adjusted carefully to achieve maximum performance. These are some guidelines to follow when fine-tuning the amplifier. For full-range and simultaneous stereo/mono bass applications, the crossover selection switch should be set to FLAT. If the amplifier is driving your subwoofers, set the switch to LPF, and for mid-bass/midrange output, set to HPF. The crossover frequency control needs to be adjusted to suit your particular system. For subwoofer applications, try to keep the setting low enough to prevent the image smearing (you should not be able to hear male voices from the subwoofer) but not so low as to create a gap between the subwoofer and the midbass/midrange speakers. For mid-bass/midrange settings, try to keep the setting low enough to keep your sound stage in front of you, without overdriving the speaker. It will be to your advantage to spend some extra time with this adjustment, listening to familiar music or system set-up discs to achieve the kind of musical reproduction that you prefer. The gain adjustment allows you to set proper signal match for clean, quiet amplifier operation. For full-range and simultaneous stereo/mono bass applications, start by playing some music you are familiar with. With the gain adjustment on the amplifier in the middle of its rotation, bring up the volume on your head unit to the 3/4 volume setting or until you start to hear distortion or clipping. If you hear distortion before you reach the 3/4 volume setting of your head unit, reduce the gain setting on the amplifier and start to raise the head unit volume again. When you can listen to the music at or slightly above 3/4 on your head unit without audible distortion, slowly raise the gain of the amplifier until distortion is heard, then back off the gain until the distortion is not audible. This setting will allow you to reach full output with all but the quietest of source material, while avoiding excessive noise in the system. For systems using the Remote Sub Level Adjustment, increase the subwoofer gain on the amplifier by 25% and set the Remote Sub Level knob to the center position after making all system gain and filter adjustments. This will give the Remote Sub Level Control a wider range of adjustment to the subwoofer output. The same procedure should be used for adjusting the amplifier when the on-board crossover is set to LPF or HPF, but you will also have to take into consideration the effect that gain adjustment has on system frequency response and imaging. Again, plan on spending some time with music that you know, getting the gain and crossover settings the way you like. Test discs and analyzers may help with this process, but in the end it's your ears that count - listen to the music! 18 © 2003 Directed Electronics, Inc SPECIFICATIONS Directed model 1200/5 Ch 1-4 Sub Ch.
