Audio connections (input)
1
OPTICAL INPUT
socket
(TOSLINK)
To connect a digital audio source using the optical signal (SPDIF / stereo PCM)
Attention: If the digital audio source has no level control, we strongly recommend using one of the
available remote-control units. Otherwise the audio reproduction will be applied at max level!
2
REMOTE CONTROL
socket
To connect one of the optionally available remote-control units
GZDSP Remote or GZDSP Touch-Remote
3
Line Input SUB
Connect the subwoofer line out of the head-unit (if available)
4
Line Input REAR
Connect the rear line output of the head-unit (if available)
5
Line Input FRONT
Connect the front line output of the head-unit (if available)
6
PC CONNECT
(MINI USB socket)
and
status indicator
To adjust the audio setting the unit must be connected to a PC using the included USB cable
(compatible Windows PC with installed DSP software from the CD). The PC can be disconnected
when the adjustment is done. The USB cable should not be extended to ensure an accurate
communication between the DSP unit and the PC. The indicator next to the MINI USB socket will
turn blue as soon as the connection has been established.
7
LINE OUT
To connect the included 4-channel RCA line out harness delivering the audio signal of channel
E/F and G/H for further amplifiers. The signal can be set using the PC software.
8
HIGH LEVEL INPUT
The High-Level Input must be used if there´s no pre-amplified output at the head-unit, nor offering
a SP/DIF signal. In this case the head-unit speaker output wires must be connected to the high-
level input harness. By using the high-level input, the DSP unit will turn on automatically
recognizing the DC level. It´s not necessary to connect the Remote-In wire to the power terminal.
Caution: The high-level input and the line input(s) cannot be used simultaneously. This may lead
to malfunction and cause serious damage to the DSP unit.
9
AUX INPUT
The 3.5 mm socket can be connected to an additional source unit. AUX can be selected as audio
source using the PC software or one of the available remote-control units.
10
PC Link switch
To establish a wired connection to the PC, the switch must be in „USB” position. The “BT” position
is without function.
11
BT BOX socket
To connect the wireless audio interface GZDSP BT-Box or the remote-control unit
GZDSP Touch-Remote – both are available optionally.
