4.0 INTRODUCTION

Thank you for purchasing a Tannoy power amplifier. This manual contains important information on operating your amplifier correctly and safely. Please take some time and read this manual to familiarize yourself with the advanced features of this amplifier.

4.1 Unpacking

Carefully open the shipping carton and check for any noticeable damage. Every Tannoy amplifier is tested and inspected before leaving the factory and should arrive in perfect condition. If found to be damaged, notify the shipping company immediately. Only the consignee may institute a claim with the carrier for damage incurred during shipping. Be sure to save the carton and packing materials for the carriers inspection.

It is also advisable to save the carton and packing material, even if the amplifier is undamaged. Should you ever need to ship the amplifier, always use original packaging.

1. Input level attenuator

This control is used to alter the signal level entering the amplifier or to cut down the unwanted noise from the input signal.

2. Crossover frequency adjustment

Continuously variable from 50Hz - 150Hz, to allow custom integration with various mid/high units and installation positions.

3. Phase control

Continuously variable from 0° - 180° to allow custom integration with mid/high units in various installation positions.

4. Crossover / Bypass switch

Allows the low pass crossover to be taken out of the circuit so an external crossover can be used.

5. On/Auto switch

In the auto position the amplifier will go into sleep mode when there is no signal present for 20-30 minutes. On position defeats the sleep mode.

6. Power indicator

This blue LED indicates that there is power present at the amp and that the rear mounted power switch is on.
