24 – A.C.
INLET
The DSP 600 features a standard IEC A.C. inlet that will accept universal power cords. The DSP 600 power supply is
auto-ranging and can accept voltages from 100 to 240 V AC, 50 to 60 Hz. Only A.C. cords approved for use in your country
should be connected to the DSP 600.
25 – A.C.
FUSE
The A.C. inlet includes a fuse holder that contains the mains fuse as well as a spare fuse. If necessary, replace the fuse
only with a specified 5x20mm, T800 mA, L250 V replacement. Disconnect A.C. power before replacing a fuse. Before
turning the unit back on, assess the condition of the A.C. receptacle powering the DSP 600. If fuses continue to blow,
refer servicing of the DSP 600 only to qualified service personnel.
26 – A.C.
POWER SWITCH
The A.C. power switch turns power to the DSP 600 On and Off.
27 – CONTROL PORT
The CONTROL PORT of the DSP 600 provides five control inputs and a reference connection for ground. The control
inputs can be used for the recall of presets.
28 – ETHERNET
INTERFACE
A computer and/or other ethernet devices (e.g. DSP 600, P 64) can be connected via the Ethernet interface for 100Base-
TX / 10Base-T Ethernet networks. Normally this connection is established via a standard (straight through) Ethernet ca-
ble and an Ethernet hub or a switch. The DSP 600 can be connected directly with a computer or another DSP 600 using
a standard or crossover Ethernet cable.
29 – B
ALANCED
XLR
OUTPUTS
Each output channel has an electronically balanced XLR connector for connection to system amplifiers. Each output
channel can output different frequency ranges depending on its assignment and cross-over settings.
CAUTION: Care must be taken to assure that each output is connected to an appropriate amplifier and loud-
speaker to avoid damage or unexpected results. Note that a new preset may change the assignment of
channel and its frequency range. For instance an output assigned to Hi frequency speakers in one pre-
set, may be assigned as a sub output in another. See “Configurations of the DSP 600”.
30 – AES/EBU THRU
PORT
The AES/EBU THRU port allows looping-through the digital audio signal to other devices. The digital input signal gets
internally buffered and preprocessed (level matching / slew rate) before it is output via the THRU connector. This allows
fairly simple wiring between devices, without the need for AES/EBU distribution amps as they are usually used. The DSP
600 has a bypass-relay, which, in case of damage (e.g. power outage), connects the AES/EBU INPUT signal directly to
AES/EBU THRU. This ensures trouble-free operation of downstream devices.
31 – AES/EBU INPUT
In addition to the analog audio inputs, an AES/EBU digital stereo input is provided and selectable in the Setup menu.
The input conforms to IEC standard 60958 Type I. Connections must be made with three conductor, 110-Ohm, twisted
pair cabling and an XLR connector. Digital audio signals in AES3 format with a sample rate from 32 kHz to 192 kHz can
be connected. Please note that the maximum cable length depends on the sample rate.
32 – LOCK LED
The LOCK LED lights green as soon as the AES/EBU input has been synchronized to the incoming signal and thus proper
audio transmission has been established. The LOCK LED is dimmed with no digital audio signal being present at the
input or the internal PLL not having locked on to the incoming signal.
33 – B
ALANCED
XLR THRU
Each analog audio input is connected to an electronically buffered and balanced output as a through connector. The
signal does not run through any digital conversion or processing. These connectors are used to pass input audio to a
second DSP 600 used as a slave or to other audio inputs in the system.
