Un-balanced Input / Output Connections
Un-balanced connections can be made to the DSP 600, although induced noise from cabling may be increased. Cables
should also be less than 15' (5 m) in length. Unbalanced connections can be 6dB lower in level as well. To match the
audio level obtained with a balanced connection, it is necessary to tie pin 3 to ground at the XLR connector. This may
increase noise.
A C (AES/EBU)
UDIO ABLE
A digital AES/EBU input (AES3) is provided in addition to the analog input. The digital input signal has to be connected
to the AES/EBU INPUT connector. The AES/EBU input is a balanced transformer-isolated input. A sampling rate convert-
er translates the input signal to match the internal sampling rate. The XLR jacks provided on the DSP 600 are configured
as pin 1 ground, pin 2 hot (+), pin 3 cold (-). Cable shielding must be connected to pin 1. XLR – XLR cables or ¼" tip-
ring-sleeve – XLR cables can both be used for balanced connections to the DSP 600.
HINT: Connections must be made with three conductor, 110-Ohm, twisted pair cabling.

THERNET
By connecting the DSP 600 via the Ethernet interface, communication between the DSP 600 and one or several PCs is
possible. This allows the configuration of DSP 600 via IRIS-Net software. The Ethernet interface on the rear of DSP 600
is a RJ-45 connector (8P8C). Both 10Base-T and 100Base-TX Ethernet standards are supported.
Status LEDs
The status of the Ethernet interface is indicated by a orange and a green LED. If the Ethernet interface is not used both
LEDs are off. The orange Link LED a the left side of the Ethernet interface lights, when the DSP 600 has established a
Ethernet connection to another device, e.g. another DSP 600 or an Ethernet switch. The green network traffic LED at
the right side of the Ethernet interface lights when sending or receiving a data packet.

ONTROL ORT
The CONTROL PORT of the DSP 600 provides five control inputs and a reference connection for ground. The control
inputs can be activated using external switches, pushbuttons or relays to connect them to ground potential, see follow-
ing example.
USB
PORT
Connecting the DSP 600 to a PC for operation via IRIS-Net application can also be accomplished via the front panel USB
port. The port conforms to the USB 1.1 Type B specification. Type B USB cables are readily available at computer deal-
ers. According to USB specifications, the cable which is connected to this interface must not be longer than 15' (5 me-
ters). The USB interface of the DSP 600 is a USB B (female) connector.
