Technical specification:

INPUTS
Power		160W 230V AC nominal, 45-65Hz.Power switch on front panel
Input 1 & 2		XLR balanced input with programmable switchable. Programmable between microphone and line via panel menu. Microphone specification; 200 - 600Ω, sensitivity -64dBu.

OUTPUTS
Loop Output Drive Voltage		33.9VRMS (48Vpk) at maximum output current per channel
Loop Output/Drive Current		D14-2 Dante

		10ARMS (14.1Apk) up to 60 seconds continuous 1kHz sine
		wave, peak >14.1A per channel

Slave Out		6.35mm jack socket to connect to other slave amplifiers
Loop Connectors		Neutrik NL2 Speakons (supplied) for each output
Loop Monitor		Provides access to monitor actual loop current via a 3.5mm stereo headphone connector on front panel Channel A on left, channel B on right

AUDIO SYSTEM
Freq.response		80Hz to 6,5kHz
Automatic Gain Control		The AGC is optimised for speech. Dynamic range >36dB
Distortion		THD+N <0.2% 1kHz sine at full current
Metal Loss Correction		Corrects system frequency response due to metal structures in a building. Gain constant at 1kHz, adjustable gain slope from 0 to 4dB per octave in 0.25dB increments. Custom 2 slope MLC allows different slopes and transition frequency to be set via the menu. This does not compensate for signal loss from metal structures which can be significant.






Phase Shift		User selectable at 0° or 90° between outputs
Fault Monitoring		Indicators on the front panel; • Clipping – delivering over the rated voltage (per channel) • Error - Check status in menu Temperature and loop errors reported via the status menu
