Introduction

The Hafler TA1100 and TA1600 are two channel, two rack height, convection-cooled, MOSFET power amplifiers suitable for use in the most demanding applications of critical listening and instrument amplification. These amplifiers offer the same outstanding sonic quality and reliability that has contributed to Hafler’s enviable reputation within professional recording studios and broadcast facilities all over the world.

This manual contains information on using the TA1100 and TA1600 amplifiers. It is organized into two main sections. “Installation” covers the location and connection of the amplifier in the system. Like many precision components, careful attention to the initial setup can yield dividends in higher performance and trouble-free use. “Operation” covers the con- trols and features of the amplifiers and how to use them to get the best effect.

The circuitry used in the TA 1600 is the latest refinement of our patented trans•nova (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 trans•nova amplifiers preferred in many critical installations. Since our pioneering use of MOSFETs in the DH-200 amplifier, they have proven extremely fault tolerant even in abusive situations. This sturdiness enables the amplifier to drive reactive speaker loads without the performance and sound penalties imposed by elaborate protection schemes.

The TA1100 trans•ana circuitry has been very successful in bringing new levels of clarity and intelligibility to many broad- cast facilities and headphone monitoring installations. Even at low power levels, the trans•ana MOSFET amplifier circuit imitates the accuracy and warmth of it’s bigger brother, the TA1600 trans•nova.

Specialized circuits in both amplifiers prevent damage to the amplifiers and speakers, without affecting the audio signal. A soft start circuit prevents sending potentially destructive turn-on and turn-off transients to the speakers. A thermal sensing network monitors the heatsink and transformer temperature, and shuts down the amplifier to protect from excessive operat- ing heat. The need for internal fuses has been eliminated; a sensing circuit monitors the output and shuts down operation when it detects a short in the output load.

The front panel has controls for input level adjustment. In addition, LED indicators give a visual representation of the oper- ating status of each channel. Any type of fault - whether it is clipping, short protection, or thermal standby - will be indicat- ed with a red LED.

Hafler manufactures additional Professional and Home Theatre amplifiers and monitors that offer an extreme level of per- formance and advanced technology. Visit our website at www.hafler.com for more information.
