Mic/Line Switch: Pads the XLR Mic input by 30 dB when pressed in. DIP SWITCH: Contains the small switches for engaging Mic 1 - 3 phantom power, the priority (Talk Over) functions, and the Mono/Stereo select. MIC INSERT: 1/4" TRS insert jack for adding external processing to the Mic signals. Tip = send, ring = return. SOURCE INPUTS: Stereo RCA jacks, Channels 1 - 4, for connection to stereo sources such as AM/FM tuners, cassette players, cd players, or video players. RECORD OUT: Stereo RCA jacks, contains all mixed signals before the Remote Volume jack, and Master Level control. SPARE: This RCA jack is not connected. MUTE: RCA jack for connection to a tip-to-ground muting circuit. REMOTE VOLUME: 1/4" TS jack for connection to a remote potentiometer for master volume control. 20K Ohm audio taper potentiometer is recommended. MAIN OUTPUTS: 1/4" TRS balanced Right and Left Outputs. 5 2 CONNECTION Connect low impedance microphones to the Mic inputs. If a paging microphone is being used, connect it to Mic Input 1 so it may be used with the Talk Over function. Connect source signals such as CD players, cassette players or video players to the RCA Source Inputs. If a jukebox is being connected, and you want its signal to mute the other source signals, connect it to Source input 4. Remote Volume Control To control the overall volume of the RM67 in a remote location, wire a 100K ohm Linear Taper potentiometer to a 1/4" Tip-Ring-Sleeve plug as shown in Fig. 1. OPERATION DIP SWITCH SETTINGS · If a microphone requires phantom power, move the Mic channel's corresponding PHAN DIP switch to the down position. This applies 12 volts dc phantom power to the indicated microphone. · Talkover switch 1 (T.O. 1), when in the down position, all program material on all inputs will be "ducked" or muted when a signal is present at Mic 1. This function is used for paging. · Talkover switch 2 (T.O. 2), when in the down position, Source 1,2, and 3 will be "ducked" or muted by the signals at Source 4. This function is for jukebox priority. With a jukebox connected to Source input 4, and the Talkover switch 2 on (down), the other Source input signals such as background music, will be muted and only the jukebox will be heard. · The Mono/Stereo switch selects the output mode. When the switch is up, the unit is in stereo mode. When the switch is down, the stereo signals are mixed to mono and sent to both the Right and Left Main output jacks. Either jack can be used as a mono output. Mic Insert To connect a signal processor to the RM67 microphone signal(s), use an insert plug, or cable wired as shown in Fig. 2. Connect the Main Right and Left outputs to your power amplifiers. The RM67 output jacks will accommodate balanced or unbalanced connections. For unbalanced operation use 1/4" Tip Sleeve jacks, for balanced operation use 1/4" Tip Ring Sleeve jacks. If a 1/4" TRS to XLR cable is needed, wire the Tip of the 1/4" jack to pin 2 of the XLR, the Ring to pin 3, and the Sleeve to pin 1 or the shield. Mute To mute all audio, connect an RCA plug to your muting circuitry. When the tip is shorted to the ground - all audio is muted. Connect the RM67 to a properly grounded AC outlet. 100 K Ohm Linear Taper Potentiometer Ring Sleeve Tip Adjust the Microphone levels for maximum input signal without clipping, and for a comfortable listening level. Adjust each Source level for a desired listening level. Fig. 1 To Mic Insert 3 Fig. 2 4
