TONE 1, 2: Adjusts the frequency content of the microphone signal in the channel. When the control is turned counter-clockwise, the high frequencies are cut, when the control is turned clockwise, the low frequencies are cut. Treble: Adjusts the high frequencies of the Source 1 and 2 signals only. Power: LED indicating power is applied to the MA2152 and the unit is on. REAR PANEL Power Bandwidth: Damping Factor: Slew Rate: Phase Shift: Power: Size: Weight: SCHEMATIC POWER AMP SECTION FUSE: 4 Amp fuse. 4 - 8 Ohm / 25 Volt Output: The two red banana jacks are used when the MA2152 is in Bridge/Mono, or 70V mode. RECORD OUT: Stereo RCA jacks, contains all mixed signals before the Master Level controls. SOURCE INPUTS: Stereo RCA jacks, Channels 1 - 3, for connection to stereo sources such as AM/FM tuners, cassette players, cd players, or video players. DIP SWITCH: Contains the small switches for engaging Mic 1, 2 phantom power, Source 3 Stereo or Mono, the priority (Talk Over) functions, and the Mono/Stereo select. MICROPHONE ONE and TWO: Balanced XLR inputs to be connected to dynamic or condenser microphones. BRIDGE SWITCH: This switch selects the output configuration; Bridge Mono, or Stereo / Dual Mono. 5 2 CONNECTION Inputs 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 1. For recording purposes, connect a stereo RCA cable to the Record Out jacks, and to your recording device. Amp Inserts To connect a signal processor to the MA2152 signal(s), use an insert plug, or cable wired as shown in Fig. This return signal is then sent to the output level section of the amplifier. Outputs In STEREO MODE, the Right speaker is connected to the red and black banana RIGHT OUTPU connectors. [. . . ] · Source 3 Priority: when in the up position, Source 1, and 2 will be "ducked" or muted by the signals at Source 1. With a jukebox connected to Source input 1, and the Talkover switch 2 on, the other Source input signals such as background music, will be muted and only the jukebox will be heard. · MONO / STEREO: When down, the output of the MA2152 is summed to mono. Either jack can be used as a mono output. FAULT PROTECTION The fault protection in the MA2152 limits the current to the output stage. [. . . ]
