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.
Input connections. As with other devices of its type, the TX2 controller is inserted in the audio chain between the last link of audio source (mixing console, preamp, CD player, etc.) and the power amplifiers. The two audio inputs are the 3 pin female XLR connectors on the rear panel, marked L for left and R for right. On each connector the signal is received between pins 2 and 3 and pin 1 is grounded. When the device connected at the input (e.g. console) and at the output (i.e.
Figure 3. TX2 front panel The way the TX2 operates with and without the sub-bass system can be seen on the simplified block diagram of Fig. 4. When the front panel push-button (left side of the SUB-BASS window) is depressed, the main - left and right - channels operate full range with the signal passing through the LF EQ section, resulting in an extension of the bottom end response of the system.
SERVICING If servicing is required, it must only be carried out by qualified personnel. Do not remove the top cover as there may be a risk of electric shock. Fuse replacement. Disconnect the TX2 from the mains power supply, and pull back the fuse drawer located at the bottom of the mains input. (A small screwdriver might be helpful.) The fuse drawer has two compartments, one containing the fuse under operation and the other a spare.
