The circuitry used in the TA1600 is the latest refinement of Hafler's patented Transnova (TRANSconductance NOdal Voltage Amplifier, US Patent 4,467,288) circuit. It has been proven to offer sound quality to satisfy the most analytic audiophile or the most demanding professional. The natural sound and realistic reproduction have made Transnova amplifiers the choice in critical installations. They have proven extremely fault tolerant even in abusive situations. This ruggedness enables the amplifier to drive reactive speaker loads without the performance and sound penalties imposed by elaborate protection schemes.
Features
MOSFET Outputs: Deliver higher output current, rugged reliability, superb sound quality.
Transnova: patented output stage configured for "power gain" allows simpler front end circuitry, dramatically lower cross talk and noise.
Soft Start Circuit prevents sending potentially destructive turn-on and turn-off transients to speakers.
Thermal Sensing Network monitors heatsink and transformer temperature and shuts down amplifier to protect from excessive operating heat.
Output Sensing Circuit monitors the output signal and shuts down operation detecting a short in the output load.
LED Status: allows you to monitor the operating status of each channel.
