The MXA Series of mixer/amplifiers combines a versatile 6-input mic/line mixer with either 35, 75,150, or 300 Watt amplification.

Mixing functions include mic/line/tel inputs, selectable automatic & manual channel muting, channel priority assignment, remote level control, tone control, a built-in limiter, an internal chime, phantom power, MOH output, and extensive patching. The amplifier includes an output transformer, and provides rated power into direct or distributed speaker systems.

The MXA Series carries a five-year warranty.

ARCHITECTS & ENGINEERS SPECIFICATION
The mixer/amplifier shall provide a 6-input mic/line mixer with an integral power amplifier. Four models shall be available, providing a choice of 35 Watt, 75 Watt, 150 Watt, or 300 Watt power amplification. The power amplifier shall include an output transformer, and shall be capable of delivering rated power into direct or distributed speaker systems. Front panel LEDs shall be provided for indication of power, signal, peak, temp, and fault conditions. The mixer shall provide six electronically balanced mic/line input channels, with one channel selectable for 600 ohm transformer telephone input. Each channel shall include 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, shall be selectable on each channel. Automatic muting shall be triggered by selected priority channels and manual muting shall be triggered by external contact closures. The output section of the mixer shall include a master level control, recessed tone controls, a low-cut filter switch, a builtin limiter with a rear panel threshold control, and an internal pre-announcement chime tone with rear panel level control. Rear panel terminals shall allow remote control of master level. Output patching shall be provided for connection of external devices for recording, signal processing, and/or system interconnections. A Music On Hold output with independent level shall be derived from input 6. Input connections shall be on plug-in barrier strips, and amplifier output connections shall be on screw terminals. Frequency Response shall be +0/-1.5dB from 20Hz to 20kHz at rated power into a direct load. THD + Noise shall be less than 0.2% at 1kHz at rated power. Equivalent Input Noise shall be -123dBu at mic input with 150W termination. Signal-to-Noise shall be greater than 78dB from 20Hz to 20kHz at line input at rated power. Power consumption shall be less than 75W (MXA35), 100W (MXA75), 150W (MXA150), or 300W(MXA300). Dimensions shall be 3.47" (2 rack spaces) high, 19" wide, and 9.8" deep. Weight shall be 17.5 lbs. (MXA35), 19 lbs. (MXA75), 21 lbs. (MXA150), or 23 lbs.(MXA300). The mixer/amplifier shall be CE marked, CSA tested to UL 60065, and shall incorporate AES48-2005 Grounding & EMC practices. The mixer/amplifier shall be compliant with EU Directive 2002/95/EC, the RoHS directive.
