INTRODUCTION
Thank you for purchasing the Tannoy TX3 loudspeaker system controller.
The TX3 is an advanced electronic controller intended to optimise the performance
of the Tannoy T300 Superdual loudspeaker system. It can be used in full range
mode where it performs specific equalisation functions, extending the low frequency
response of the T300 significantly. It can also 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 TX3 also features:
• Stereo operation.
• Balanced inputs and outputs.
• Individual sub level control.
• Low frequency EQ mode switch intended to tailor low frequency for
floorstanding/monitor applications.
• Low frequency phase invert switch.
• 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. Please take a few minutes to read it prior to installation.
OPERATING INSTRUCTIONS
Preliminary advice and information.
The information contained in this manual is relevant for the TX3 controller only. The
TX3 is dedicated for use with the Tannoy T300 loudspeaker system only.
Degradation of the sound quality and unreliable operation will result if using an
improper controller.
The Tannoy TDX1 digital loudspeaker management system should be used for fully
active operation. If you intend to use an OEM crossover/controller (i.e. Omnidrive,
XTA) then contact Tannoy or your distributor for the correct operational
parameters.
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 TX3 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.
