Page 19: Output Limiters
7.6. Output Limiters High performance digital limiters are provided for each output with control over attack time, release time and threshold level parameters (see Section 8.2, page 22). This level of control allows the user to balance the required subjective quality of the limiter against the driver protection requirements. -

Parametric filters are carefully implemented using Double Precision processing. This method is costly in terms of processing power but yields substantial benefits in terms of the TDX2’s exceptional noise performance and greatly improved low frequency stability. To adjust parametric settings: Select relevant channel by pressing the channel ‘GAIN’... -
Page 21: High And Low Pass Filter Screens
8.2. High and Low pass filter Screens OP1+4 < 10Hz Each output has an independent high pass filter and an independent low pass filter. Both filters have a range of selectable slopes, which are Bessel 12dB, 18dB and 24dB, Butterworth 12dB, 18dB and 24dB, and Linkwitz-Riley 24dB. High pass filters have a range of <10Hz (through) to 16kHz and Low pass filters have a range of 22kHz (through) to 35.1Hz in 1/36 octave steps. -

Page 31: Operating Notes
With any audio signal processing equipment it is necessary to ensure adequate signal level is used through the device, to avoid sacrificing noise performance. The TDX2 features a menu selectable choice of operating levels to reduce this problem (see section 8.6) It is suggested that the operating level chosen should give adequate level to just light the -6dB LED on the headroom meter with maximum program level being used. -
Page 32: Warranty
13. Warranty No maintenance of the TDX2 is required. 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. All Tannoy electronic components are guaranteed for a period of one year from the date of shipment, subject to the absence of, or evidence of, misuse, overload or accidental damage. -
