With the help of this manual you will be able to maximise the enjoyment that you will get out of your new 42.29 Mono Amplifier. This amplifier incorporates many advanced technical features and performances. Therefore, it is essential that all signals sources, speakers and interconnection devices are of the highest sonic quality. We strongly recommend the use of MACROM head units, power amplifiers, speaker systems, high-quality interconnection cables and accessories, because the integration of all these products is very complex. We therefore advise that you have installed the 42.29 by your MACROM dealer. This product has no user-adjustable controls; read this manual carefully in order to become well acquainted with all the special features and functions of your new MACROM 42.29. Do not hesitate to contact your MACROM dealer should you have any problem. PRECAUTIONS 1. The unit may be damaged by wrong lead connection, therefore read carefully the instructions of this manual for the correct connection of the leads. 2. The last lead to be connected is the one to the positive (+) terminal of the battery; connect this lead only after having completed and checked all other connections. 3. Be sure to install the crossover in a position with good air circulation and good heat dissipation. 4. In case of fuse replacement make sure to replace it with a fuse of the same amperage. If fuses blow more than once, carefully check all electrical connections. Also have your car's voltage regulator checked. Do not attempt to repair the unit yourself. If repairs are ever needed, take the unit to your MACROM dealer or to your nearest MACROM service station. 5. In order to get the best possible performance from this unit, make sure that the temperature inside your car is within the range of -10° C and +60° C before you switch the unit on. Good air circulation is essential to prevent heat build-up inside the unit. FEATURES · LOW-PASS FILTER THAT CAN BE SET AT THE END SECTION · PRE-OUTPUT WITH "FLAT, HIGH- OR LOW-PASS FILTER" SELECTOR · CONTINUOUS AND INDEPENDENT ADJUSTMENTS OF THE FREQUENCY CUTOFFS · INPUT MODE SELECTOR: MONO, STEREO OR MIX · CONTINUOUS ADJUSTMENT OF INPUT SENSITIVITY · MOS-FET POWER SUPPLY · "CHECK CONTROL" STATE INDICATOR · REMOTE ON AND OFF · GOLD-PLATED RCA INPUT CONNECTIONS · PROFESSIONAL GOLD-PLATED SCREW-TYPE SUPPLY TERMINALS 6 CONTROLS AND INDICATORS 1 · RCA INPUT CONNECTORS: connect the pre-output leads of the head unit to the input connectors. L(mono) ST L+R 2 · INPUT MODE SELECTOR: allows to select the amplifier 's L(mono) ST L+R configuration as follows: a) STEREO "ST" when the amplifier is used as a two-channel stereo system (right + left); L(mono) ST L+R b) MONO (L mono) when the amplifier is driven by one input signal "Left" and outputs are mono-bridged. NOTE: in this configuration, no signal is present at the "Right" pre-output RCA output connection; c) MIX "L+R": when the amplifier is designed to drive one or more subwoofers according to the 1-, 2- or 3-channel configurations. Thus, the inputs signals will be blended into one signal. NOTE: anyway, the signals present at the Pre-output outputs will always be stereo. 3 · INPUT GAIN ADJUSTMENT CONTROL: input sensitivity ranges from 200 mV to 2V. Set the mid position for all MACROM units. In case the amplifier is to be connected to a head unit that is not of MACROM make but is fitted with preamplified RCA outputs, proceed as follows: a) set the volume control of your head unit to 3/4 of maximum ouput Flat Low level; b) set the input gain control to the point where the maximum sound 20Hz 20kHz Flat Low level with no distortion is obtained. 4 · LOW-PASS SELECTOR SWITCH: it allows to select the amplifier's output mode by activating the Low-Pass crossover. a) Flat: the amplifier reproduces the whole range of frequencies from 20 Hz to 20kHz b) Low: the amplifier reproduces low frequencies only. 5 · LOW-PASS FREQUENCY ADJUSTMENT: allows the continuous adjustment of the low-pass frequency between 30 and 600 Hz, to determine the end point of the audio range present at the amplifier's outputs and at the Pre-output outputs should the low-pass filter be selected. 20Hz 30>600Hz 150Hz 100Hz 250Hz 70Hz 340Hz 45Hz 470Hz 36Hz 520Hz 33Hz 580Hz 30Hz 600Hz 6 · HI-PASS FREQUENCY ADJUSTMENT: allows the continuous adjustment of the high-pass frequency between 30 and 600 Hz, to determine the starting Flat Low High value of the audio range present at the Pre-Output outputs. 7 · PRE-OUTPUT SELECTOR SWITCH: allows to select the 20Hz 20kHz Pre-output output mode as follows: Flat Low High a) FLAT: a signal having the same form and amplitude as the input signal is present at the Pre-output outputs; 20Hz 30>600Hz b) LOW: a low-pass signal is present at the Pre-output outputs Flat Low High in order to drive an additional amplifier. Frequencies can be adjusted by means of the LOW-PASS FREQUENCY "5" 30>600Hz 20kHz control; c) HIGH: a high-pass signal is present at the Pre-output outputs in order to drive an additional amplifier. Frequencies can be adjusted by means of the HIGH-PASS FREQUENCY "6" control. 7 CONTROLS AND INDICATORS 8 · PRE-OUTPUT RCA OUTPUT CONNECTORS: connect to an additional amplifier to be used according to the mode previously selected. 9 · SPEAKER CONNECTOR: outputs for speakers connection. The amplifier allows to connect speakers with minimum 1-ohm impedance per channel in stereo configuration and with minimum 2-ohm impedance in mono-bridged configuration. Should the 3-channel configuration be used, total impedance must not exceed the minimum 2-ohm value. Be sure to keep the right polarity and phase in connecting the speakers. Avoid any contact between poorly insulated wires and the car's ground or metal pieces and between the wires themselves. + + + + L BRIDGED + R BRIDGED L + R + + L BRIDGED + R 3-channel configuration 2-channel configuration 1-channel configuration 10 · FUSE: in case of fuse replacement make sure to use fuses of the same amperage. The use of fuses with the wrong amperage may seriously damage the components of the unit. 11 · BAT + CONNECTOR: to be connected directly to battery + by means of a fuse located close to the battery itself. Utilize a cable having an adequate section. Do not connect this cable to the car's electrical ...
