Orion Car Audio DEQ 30 - Manual (Page 16)

The DEQ 30 can accept a direct digital signal from a Compact Disc, Mini Disc or DAT source unit (44.1 kHz and
48 kHz sampling frequencies). Both TOSLINK and COAX connectors interface with a professional grade SPDIF
receiver. That allows direct access to the digital processor inside.
SELECTING DIGITAL INPUTS
The Analog/Digital push button selector switch determines whether analog or digital inputs are used.
When the push button switch is in the ‘out’ position, the DEQ 30 is configured for analog input (RCA or
Balanced). When the push button switch is in the ‘in’ position, the DEQ 30 is configured for digital input
(TOSLINK or COAX). When the digital output is selected, the level button when pressed accesses a
digital attenuation control. This can be used for a volume control or to set the digital level of the
system.
The TOS/COAX push button selector switch determines whether the TOSLINK or COAX digital input is
used. When the push button switch is in the ‘out’ position, the DEQ 30 is configured for TOSLINK
(optical) digital input. When the push button switch is in the ‘in’ position, the DEQ 30 is configured for
COAX (cable) digital input.
