    Rack Mounting The ACM604 is supplied with rack ears attached to allow mounting within a standard 19” equipment rack. As is the case with almost all audio products, adequate ventilation and air flow is required. When installing multiple ACM amplifiers within the one rack, it is recommended that at least 1 rack unit of ventilation space is left between every two amplifiers.
  • Page 5 VOX Muting The ACM604 includes a VOX muting circuit which is independent for each amplifier. The unit is factory set so that input 1 of each amplifier has VOX priority over inputs 2 and 3 for that amplifier. Basically, when signal is present on input 1, audio from inputs 2 and 3 is muted.
