C7-1 Perimeter Hearing Loop Driver

INPUTS
Input 1 & 2: 3 way 3.5mm euroblock screw terminal input (supplied) with a balanced microphone and line level operation, selectable via rear panel switch. Switchable 250Hz low cut filter. Priority input option (network models only).
Microphone / Line: Microphone specification; 200 – 600Ω, sensitivity -67dBu. Selectable 24V phantom power on microphone only Line sensitivity -42dBu. Max line level 17Bu. Max mic level -8dBu.
100V Line (Input 2 only): 2 way 5mm euroblock screw terminal (supplied) Sensitivity +7dBu
Dante (Optional C5/C7): RJ45 Ethernet, control and monitoring. Hosted web server, Telnet & SNMP.

OUTPUTS
Loop Connectors: 4 way 5mm euroblock screw terminal (supplied) for each output, for twisted pair or star-quad configured feed cables
DC Output*: 2 way 3.5mm euroblock screw terminal (supplied). Re-settable, fuse protected 12V 0.1A. Controllable to reflect amplifier status (network models only)
Status Relay (C10 and C14): 2 way 3.5mm euroblock screw terminal (supplied). Normally closed isolated relay contacts, open in fault conditions. Rated load 0.5A at 125VAC, 2A at 30VDC.
Line Output: 3 way 3.5mm euroblock screw terminal (supplied) post AGC balanced output
USB*: Firmware updates or power for wireless router (200mA max).

AUDIO SYSTEM
Frequency Response: 80Hz to 6.5kHz
Distortion: THD+N <0.3% 1kHz sine at full current
Automatic Gain Control: The AGC is optimised for speech. Dynamic range >36dB
Metal Loss Correction: Corrects system frequency response issues 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 dual slope MLC allows different slopes and knee frequency to be set via the menu (network models only). This does not compensate for signal loss from metal structures which can be significant.
Phase Shift: User selectable (network models only) at 0° or 90° between outputs
