 “INPUTS” Panel

TwK™ 88:  Inputs are numbered from 1-8, corresponding to the connection 

labels on the TwK™ 88 hardware. The adjacent Input Labels can be edited via 

the PC’s keyboard.

Input Settings: click on the “Menu” 

 

 to access the Input Settings 

Menu (TwK™ 88 only)

Input Sensitivity: Adjustable from 250 mV (default) to 7.1 V, in 3 dB 

steps. Designed to match the output level of your source unit’s analog 

outputs to the TwK’s analog-to-digital converter. (Refer to Appendix A 

on page 15 for more info.) Input Sensitivity is not adjustable with digital 

inputs.

Input 1 & 2 Connection Type (TwK™ 88 Only): Inputs 1 and 2 can 

receive Analog signals via RCA connections. They can also be set to 

receive Digital Optical or Digital Coaxial signals in 2-channel S/PDIF 

format from the appropriate connectors on the TwK™ hardware. Please 

note that this particular selection applies to all presets. If you wish to 

switch between digital and analog inputs via PRESET selection, do not 

connect analog inputs to Inputs 1 & 2. Use other inputs.

 

TwK™ D8: The TwK™ D8 has only one input: Digital Optical. There are no 

Input Settings to adjust.

 

 “INPUT MIXER” Panel

The INPUT MIXER directs input signals to the EQ Banks and has the 

ability to combine input channels. It uses an intuitive clickable interface that 

provides visual feedback of input signal routing. In Advanced and Expert 

modes, additional mixing flexibility is enabled by permitting input polarity 

and relative level to be adjusted to create spatial effects.

Pre-EQ Level Trim:

Allows the output levels of the mixer to be reduced as much as –12 dB, 

prior to being routed to the EQ Banks. These controls should be left at 0 

dB (highest setting) in most use cases.

 “EQUALIZERS” Panel:

A unique aspect of the TwK™ signal flow design is the ability to assign as 

many (or as few) EQUALIZERs as you need for your system design. The 

TwK™ DSP has a total of eight EQ banks, each with 10-bands of equalization. 

With eight EQ Banks available, you have the option to assign one to each 

Output Channel. Alternatively, you can assign as few as one pair of EQ 

Banks to all eight Output channels… or any number in between.

One particular advantage of this approach is that you can configure your 

TwK™ to equalize by system zone. Let’s consider just one example: you have 

a 3-way system in the main zone: tweeters, woofers and subwoofers, and 

the second zone only contains rear “fill” speakers. With the flexibility of the 

TwK™ EQ Banks, you can assign one pair of EQ’s to tune the entire front 

zone (tweeters, woofers and subs), and another pair of EQ Banks to tune
