Overview

The C Series hearing loop drivers from Ampetronic mark a substantial development in assistive listening technology. Compact, elegant, and sturdy, C Series units feature digital signal processing and networking functionality. The drivers feature a simple digital user interface, enabling accurate adjustment and providing clear indicators, system diagnostics, and built-in test tones. C Series drivers are fully networkable with a Wi-Fi accessible standard browser-based control panel for remote set-up, monitoring, and email alerts.

The C7-2N features 7.0 Amps RMS current loop output and two channels, plus ample voltage headroom, making it suitable for a wide range of applications. Fast, accurate installation can be performed with total confidence; unique, multi-stage filtering ensures compatibility with other systems and global EMC regulations.

Configurations & Architectural Specs

Configurations

C7-2N C Series MultiLoop™ Networkable Driver (7.0 Amps x 2)

Architectural Specs

The C Series MultiLoop™ Driver shall continuously deliver two (2) 7 A(RMS) per channel when excited with a 1 kHz sine wave as measured with the IEC 62489-1 induction loop amplifier performance standard. Only drivers that have been tested and compliant to this IEC 62489-1 specification shall be accepted, no other substitutions will be allowed.

In a Perimeter Loop application it shall cover up to two (2) x 460 sq. m (4,952 sq. ft.) each. In a MultiLoop Low Loss application it shall cover up to 1089 sq. m (11,819 sq. ft.) The MultiLoop driver shall internally incorporate two (2) loop drivers and one (1) accurate and stable 90° audio phased shifter. The MultiLoop driver with the proper design shall have reduced spill to no more than 1.5 m (4.9 ft.). The driver shall have a frequency response of at least 80Hz to 6.5kHz +/- 3 dB with THD+N less than 0.2%. The unit shall incorporate (AGC) Audio Gain Control optimized for speech with a compression dynamic range of >36 dB audio processing. The unit shall incorporate Dual Slope Metal Loss Correction to rectify frequency loss caused by adjacent metal structures. The unit shall incorporate built in test signals and shall be fully networkable with a Wi-Fi accessible standard browser based control panel for remote set-up, monitoring and email alerts.  The unit shall occupy one rack space and rack mount brackets shall be included. The Single Loop driver is tested to and compliant with: IEC 62489-1 induction loop amplifier performance standard.

The C7-2N C Series MultiLoop™ Networkable Driver (7.0 Amps x 2) is specified.

Outputs

Loop Output Drive Voltage20VRMS (28Vpk) at maximum output current per channel
Loop Output/Drive Current7ARMS (10Apk) up to 60 seconds continuous 1kHz sine wave, peak >10A per channel Cont. pink noise 3.3ARMS short term peaks >10A per ch.
Loop Connectors4 way 5mm euroblock screw terminal (supplied) for each output, for star-quad configured feed cables
DC Output2 way 3.5mm euroblock screw terminal Re-settable, fuse protected 12V 0.1A.
Line Output3 way 3.5mm euroblock screw terminal (supplied) post AGC balanced output

Audio System

Frequency Response80Hz to 6.5kHz
DistortionTHD+N <0.3% 1kHz sine at full current
Automatic Gain ControlThe AGC is optimised 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 (web only) at 0° or 90° between outputs
