8 1. Introduction Thank you for choosing the Tannoy TDX2 loudspeaker system controller for your application. The TDX2 is an advanced digital electronic controller intended to optimise the performance of Tannoy loudspeaker systems. This manual explains how to configure the TDX2 to be tailored to your specific application.
9 • Six high performance limiters are provided, featuring a wide range of control over Attack, Release and Threshold parameters. The output meters shows headroom to the limit threshold. The me ter time constants track the limiter time constants to show precise power usage.
10 4. Front Panel Functions 1. LCD Display - Shows menu options, output information and various parameters being a djusted. 2. Gain Keys - Two input and six - output ‘gain’ keys allow instant access to the gain screen for each channel. When a channel is selected the accompanying LED lights up.
11 5. Rear Panel Functions 1. Power Switch . 2. Mains Fuse - Located in a finger - proof fuse holder adjacent to the mains inlet. Always replace this fuse with the correct type as shown on the rear panel legend. (N.B. A spare fuse is located in this holder.
12 6. Operating the TDX2 6.1. Preliminary Set - up The following procedure should be followed when first installing the TDX2. Connect the unit to a mains o utlet with the mains cable provided, via the IEC connector located on the back of the unit. The unit is switched on by flicking the power switch.
13 6.4. Menu S elections The following menu selections are available. To access menus, see instructions under preliminary set - up above. Xover Sub - Menu : Load a Xover: Loads a pre - defined crossover. Design a Xover: Set - up wizard for designing a crossover.
14 7. TDX2 Configurations 7.1. Introduction To simplify set - up of the TDX2, 5 crossover modes are menu selectable. Thes e all have parametric equalisers, high and low pass filters, limiters, gain and delay. For detailed information on these modes please study the block diagrams along with the following descriptions.
15 distance (System Su b - menu) and is adjustable in 2 . 6 µ S steps (1mm), or in 0.8mm (or 0.003 feet) steps. Alternatively, to convert from units of time (i.e. milliseconds) to units of distance use the following formula, or change the input method in ‘delay time/distance’ in the S ystem Sub - Menu.

19 7.6. Output Limiters High performance digital limiters are provided for each output with control over attack time, release time and thresho ld 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.
20 8. Function Screens 8.1. Parametric Equaliser Screen All modes feature a total of 30 bands of fully flexible parametric equalisation (5 per output), with all sections selectable to Low or High frequency shelving response.
21 8.2. High and Low pass filter Screens 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.
22 8 .3. Limiter Screen Each output has an independent high performance limiter. All limiters have an attack range of 0.3mS to 90mS, release times are 4, 8, 16 and 32 times the attack time and thresholds range from +22dB to – 10dB in 1dB steps.
23 8.4. Delay Screen Each output has an independent delay time control. This can be adjusted in 2 . 6 µ s steps and in 1ms steps giving complete control over driver time alignment. Input delay (base delay) is adjustable in 1ms steps only. To adjust the delay settings: Select relevant channel by pressing the channel ‘GAIN’ button.
24 8.6. Gain Screen Each output and input has an individual gain screen. The outputs have a range of +15dB to – 40dB, adjustable in 0 . 1dB steps and the inputs have a range of +6dB to – 40dB, again adjustable in 0 . 1dB steps. To adjust the gain: Select relevant channel by pressing the channel ‘GAIN’ button.
25 9. Menu Options 9.1. X - over Sub - Menu Press 'MENU' and select X - over Sub - menu using the ‘BACK’ , ‘NEXT’ and 'ENTER' keys. Four options are available in this sub - menu which are: Load a Xover : Loads a stored crossover.
26 including all menus. Changes + view: This option locks all parameters and the viewing of them on the LCD including all menus. Changes + mutes: This option locks all parameters, including all menus, and disables all mute keys. Everything: This option locks all parameters and the viewing of them, including all menus, and disables all mute keys.

31 12. Operating Notes 12.1. Operating Level 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.
32 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 co ver, as there may be a risk of electric shock.
