ATI MMA Serie Line and Mic Amplifiers give you four or eight individual channels to boost either line or mic level balanced inputs up to +24dBm, 600 ohm line levels with either active or transformer balanced outputs.
Use these versatile units as microphone, line buffer, IHF interface, audio distribution and level matching amplifiers. Drive headphones or interface phone lines. Combine channels with rear connector jumpers to form stereo summing networks, DAs, simple mixers or even a Press Box. Adjustable gain, up to 82dB mic and 42dB line. Low noise and distortion, ruler flat response. Barrier block terminals, 1RU rack mount; accessory XLR input & output panels available.
- Four or eight, high or low gain audio channels
- Rear panel jumpers to combine input channels to multiple outputs
- Drive multiple outputs at different gain settings
- Combine high and low gain microphone inputs into many outputs
- Normalize incoming telephone lines and drive outgoing feeds with a Multiple Line
- Amplifier array.
| GAIN | MMA400/MMA800: 64, 74 or 84dB; |
|---|---|
| Each channels gain is dependent on output gain jumper plug position | |
