INTRODUCTION

Thank you for purchasing the Tannoy TX2 loudspeaker system controller.
The TX2 is an advanced electronic controller intended to optimise the performance

of Tannoy loudspeaker systems. It can be used in full range mode where it performs
equalisation functions, extending the low frequency response of the system
significantly. Also, it can be switched to 2-way active mode for applications requiring
greater capability at very low frequencies, where it provides a mono sub channel
output with optimised high and low pass internal crossovers.

The TX2 also features :

• stereo operation.

• balanced inputs and outputs.

• individual sub level control.

• high pass filters to protect against hazardous ultra low frequencies.

• industry standard 19’’ rack-mounting

As well as technical specifications, this manual contains some helpful advice on how
to use the controller. Thank you for taking a few minutes to read it prior to
installation.

OPERATING INSTRUCTIONS

Preliminary advice and information.

The information contained in this manual is relevant for all TX2 controllers although
versions will vary with different internal adjustments for equalisation or cross-over
sections. Each version is dedicated for use with a specific Tannoy loudspeaker
system. Make sure that the controller you are planning to use is suitable for your
loudspeakers, as degradation of the sound quality and unreliable operation could
result from an improper combination.

Please inspect the unit immediately after unpacking for signs of transit damage. In
the unlikely event that this has occurred please inform the carrier and the supplier. It
is always a good idea to keep the carton for possible future transportation.

Before the TX2 is connected to the mains supply, make sure that the unit is
selected for operation with the correct mains voltage. This can easily be checked

by looking at the rear panel, where the selected input voltage appears on the voltage
selector itself, located near the mains socket. Where necessary, change the selection
by sliding the switch to the correct position. The position marked 115V is suitable for
any mains voltage from 100V to 120V, whereas the position marked 230V will suit
any voltage between 220V and 240V.
