One of the current trends in commercial installations is the requirement for more power. The MXA Series mixer/amplifiers deliver on that promise having been built on the bedrock of the CMA Series, but offering improvement with four more powerful models: 35W, 75W, 150W, or 300W power amplification, each in a 2 RU space. Each model in the series provides a six-input mic/line mixer with an integral power amplifier, including an output transformer for delivering rated power into direct or distributed speaker systems. More accurate setup is possible with back panel peak indicators, which are a new feature.
Adding to the versatility of the MXA Series in a commercial application, one channel of the six electronically balanced mic/line input channels is selectable for 600 ohm transformer telephone input. For easy access, making quick adjustments a reality in commercial applications, each channel includes a rear panel trim control with peak indicator, a front panel level control, and a rear panel +48V phantom power switch. Automatic and/or manual muting, by -20dB or -80dB, is selectable on each channel, making the MXA ideal for a wide range of installations. Selected priority channels can trigger the automatic muting, while manual muting can be triggered by external contact closures.
Easier installation is achieved with the incorporation of Phoenix connectors. On the output section of the mixer, integrators will find a master level control, recessed tone controls, a low-cut filter switch, a built-in limiter with a rear panel threshold control, and an internal pre-announcement chime tone with rear panel level control. Rear panel terminals allow remote control of master level. Output patching is also provided for connection of external devices for recording, signal processing, and/or system interconnections. For systems that require a Music On Hold output with independent level, it can be derived from input 6. This is especially useful in retail and hospitality installations where a dedicated channel is required with its own level control that won't be affected by adjustments to the other channels.
