C-Series MultiLoop Driver 5A

Item:C5-2

The C5-2 Series hearing loop drivers from Ampetronic mark a substantial development in assistive listening technology. C Series units feature digital signal processing and networking functionality, and enable fast, accurate setup and adjustment via a very simple and easy to use user interface and built-in test tones.

Available in Non-Networked (C5-2), Networked (C5-2N), and Dante (C5-2D) versions.

Engineered to offer the high end performance, consistency and certainty of results associated with top of the range hearing loop drivers, all for the price of a mid-range amplifier. Class ‘D’ drivers built into the C Series ensures low running and maintenance costs.

Network and Dante versions enable installers, technicians and facilities managers to remotely control the driver and monitor its condition status along with resistance and induction measurements. Fault condition alerts via email or Telnet provide reassurance that an operator will be informed of any issues with performance delivery.

The C5-2 features two 5 Amps RMS current loop outputs, plus ample voltage headroom, making it suitable for a wide range of applications. Installation can be performed with total confidence; unique, multi-stage filtering ensures compatibility with other systems and global EMC regulations.

+Outputs

Loop Output Drive Voltage20VRMS (28Vpk) at maximum output current per channel
Loop Output/Drive CurrentDrive Current: 5ARMS (7Apk) up to 60 seconds continuous 1kHz sine wave, peak >7A per channel Cont. pink noise 2.3ARMS short term peaks >7A per ch.
Loop Connectors4 way 5mm euroblock screw terminal (supplied) for each output, for twisted pair or star-quad configured feed cables
DC Output2 way 3.5mm euroblock screw terminal Re-settable, fuse protected 12V 0.1A. Controllable to reflect amplifier status (network models only)
Line Output3 way 3.5mm euroblock screw terminal (supplied) post AGC balanced output
Status Relay (C10/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.
USBFirmware updates or power for wireless router (200mA max). Powering external devices may reduce power headroom for the loop, DC output and USB power should not be used simultaneously.

+Audio System

Frequency Response80Hz to 6.5kHz
DistortionTHD+N <0.3% 1kHz sine at full current
Automatic Gain ControlThe AGC is optimized for speech. Dynamic range >36dB
Metal Loss CorrectionCorrects 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 2 slope MLC allows different slopes and transition 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 ShiftUser selectable (network models only) at 0° or 90° between outputs
