Housed in a convenient 2U package, the MA6.8Q 4-channel amplifier allows for the adjustment of maximum voltage peak, gain adjustment and has on-board network capability for monitoring and control. With these features it is now possible to specify identical amplifiers in an installation and then adjust each output to the very specific requirements of the speaker system. A typical large-scale system is a combination of high-powered speakers, full range in-fill speakers, 70/100V ceiling speakers, with an active speaker management system. With switchable outputs and on-board network capabilities, the MA6.8Q can be designed into a complete value engineered system handling all amplification tasks. www.martin-audio.com overall dimensions technical specifications MAX OUTPUT POWER Four Channels 16Ω PER CHANNEL 650 W 8Ω PER CHANNEL 1200 W 4Ω PER CHANNEL 1700 W Hi-Z: 70/100V 1600 W MAX OUTPUT VOLTAGE PER CHANNEL 100 Vrms DISTORTION THD 20Hz – 20kHz FOR 1W 0.1% THD AT 1kHz AND –1dB BELOW CLIP 0.05% SIGNAL TO NOISE RATIO 112dBA CHANNEL SEPARATION @ 1kHz 70dB FREQUENCY RESPONSE +0/-3dB 6.8Hz – 34kHz INPUTS GAIN SELECTABLE (dB) 23, 26, 29, 32, 35, 38, 41, 44 DEFAULT GAIN 35dB FRONT PANEL GAIN CONTROLS 21 position detent INDICATORS: (common) NomadLink® Network connected Blue LED Power Average Limiter Red LED Power On Green LED Option Card (on) Yellow LED FRONT PANEL INDICATORS: (per channel) Signal present / Hi impedance warning Green/Red LED -10dB and –4dB output signal present 2 x Green LED Voltage Peak Limiter (VPL) clipping Red LED Current Peak Limiter (CPL) active Orange LED Very High Frequency (VHF) warning Yellow LED High Temperature warning Yellow LED Fault warning 2 x Yellow LED Mute 2 x Yellow LED REAR PANEL INPUT CONNECTORS 3-pin Phoenix, electronically balanced OUTPUT CONNECTORS Barrier strip 2-pole screw terminals POWER OPERATION VOLTAGE 130-265 V / 65-135 V MINIMUM POWER-UP VOLTAGE 230V / 115V 171V / 85V POWER AVERAGE LIMITER Yes SOFT START / INRUSH CURRENT DRAW Yes / max 5A DIMENSIONS WIDTH 483mm (19ins) HEIGHT 88mm (3.5ins) 2U DEPTH 343mm (13.5ins) WEIGHT 12kg (26.4lbs) electronics
