Input Connections
For maximum versatility, the TwK
88 is equipped with three methods for
connecting input signals. Select the input type that is appropriate for the specific
equipment of your audio system.
Line-Level Analog Inputs: Eight female RCA jacks accept low-voltage, line-
level audio signals, with configurable input sensitivity settings (up to 7.1 V
RMS) using the TüN
Software Interface. Engineered to combat induced cable
noise, the input architecture is set up in a differential-balanced configuration,
making these inputs compatible with virtually any analog, line-level audio
signal.
Optical Digital Input: Toslink jack accepts 2-channel digital audio signal from
any optical (S/PDIF) digital output, with a sample rate up to 96 kHz.
Coaxial Digital Input: Female RCA jack accepts 2-channel digital audio signal
from any coaxial (S/PDIF) digital output, with a sample rate up to 96 kHz.
Functionally identical to the TwK
88, the TwK
D8 is equipped with an optical
(Toslink) digital input only. This connection preserves a pristine signal path in the
digital domain and is intended for systems equipped with an optical (Toslink)
digital output, such as our FiX
82 OEM integration DSP.

Output Connections
Both TwK
88 and D8 models offer two output types to feed audio signals to your
aftermarket system. Select the output type that is appropriate for the specific
equipment of your audio system.
Analog Outputs: Eight RCA-type, 4-volt (RMS) line-level output jacks are
located next to the “Power Connector. Each channel pair is arranged
together by letter (A-B, C-D, E-F, G-H), with each channel labeled (Left and
Right). Analog outputs are compatible with most types of aftermarket signal
processors or amplifiers. The level of this output is proportionate to the
TwK
s input signal and may also be controlled by the included DRC-200 Digital
Remote Controller.
Optical Digital Output: Located next to the Analog Outputs (A-H)”, this jack
provides a digital audio output that is not susceptible to RF interference or
noise-generating electrical conditions. This is a pass-through digital audio
output, with no signal processing applied, and intended for use with other
signal processors or amplifiers that have an optical (Toslink) digital audio input
(S/PDIF) jack. Using the TüN
Software Interface, you may select which analog
inputs are assigned to this output. The level of this output is fixed and is not
affected by the included DRC-200 Digital Remote Controller. However, when
Analog Inputs are selected as the Optical Digital Output’s source, the level of
this output will match the analog input sensitivity settings.
