Ampetronic has engineered the C Series to offer the high end performance, consistency and certainty of results usually 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 C5-1 features 5 Amps RMS current loop output, 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. These products are designed to form part of a system that can meet all of the requirements of the international loop performance standard IEC60118-4, and the relevant parts of IEC TR 63079.

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
