TA 1600 - SHORT CIRCUIT PROTECTION

The TA1600 amplifier circuit has no need for sonically degrading voltage and current limiting circuits. To protect the amplifi- er from problems which may occur in the speaker line there is an overload detection circuit.

In the event of a short in the speaker load or cables, the speaker detection circuit will shut down that channel and light the red front panel indicator. If this happens, correct the fault and turn the amplifier off, then back on. This will reset the amplifier.

WARM UP

In order to achieve the best sonic performance from the amplifier, we recommend letting it warm up for 1 hour before begin- ning any critical listening. The amplifier may not deliver its full potential sound quality before this time has passed. Many users leave Hafler amplifiers on indefinitely to ensure the best operation without delay.

CLEANING AND MAINTENANCE

There is no requirement for regular maintenance on the electronic components of the amplifier. If the case becomes soiled it can be cleaned using a soft cloth and a mild detergent, such as spray window or glass cleaner. If the amplifier is located in a particularly dusty environment cleaning the inside with compressed air or vacuuming every 18 to 24 months is sufficient.
