SETUP TAB

"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"
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
to access the Input Settings
