Figure 2 – Rear Panel

All input and output connectors are mounted on the rear panel. Individual connectors are clearly identified by the panel legend. Viewed from the rear from left to right, the connectors are as follows:

Balanced Analogue Outputs

3 pin XLR male (2 off)

Unbalanced Analogue Outputs

RCA phono (2 off)

Output Level Adjustment

(trimmers)

Two multi-turn potentiometers set the full scale output levels for the Balanced Outputs only. These are factory preset for full scale with output levels of +14dBu. If necessary, adjust with a suitable trim tool or a small flat-bladed screwdriver. Turn clockwise for increased gain. Take care to ensure the stereo outputs remain in balance. The trim range is ±6dB.

Reference In

3 pin XLR female

Reference Out

3 pin XLR male

Reference In is an AES/EBU reference input for synchronising the unit to a Master Clock. Reference Out is an unbuffered loop through, directly coupled to it, for use in a reference daisy chain. A terminating resistor may be turned on or off, using the menu (see Ref In command, page 23), if several units are to be daisy chained with the same word clock.

AES1, 2, 3 & 4 Digital Inputs

3 pin XLR female (4 off)

Four AES/EBU inputs which may be used independently or in groups of two (Dual AES on AES1 & 2 or on AES3 & 4) or four (Quad AES or 4-wire DSD).

P3D units will also accept DSD in P3D format connected to AES1, 2 & 3.

SDIF/DSD CH1, CH2 Data

BNC (2 off)

These BNC connectors can be both inputs and outputs. In normal operation they are inputs for SDIF-2 encoded PCM, or SDIF-2 or SDIF-3 encoded DSD. They are both TTL level signals for a 75 ohm line. They can be set to accept TTL level AES3 coded signals, using the menu (see BNC I menu command, page 26).

In addition, they can be used as data outputs, for re-formatting DSD data, in DDC mode. See the Ref In menu command on page 23.
