X-Rack Master Module

F. The Master Module

F.1 Introduction

Used in conjunction with the XR623 X-Rack Line Return module, the XR622 X-Rack Master module

provides a complete small scale mix and monitor system for studios seeking a compact solution for mixing

and monitoring in the analogue domain. A single X-Rack can provide up to 28 line level inputs. Additional

racks can be connected via the ‘MIX BUS LINK’ connector on the rear of the X-Rack unit, allowing

additional inputs to be added to the system if required.

Note. X-Rack units prior to serial number XRK0110 are

not

equipped with a ‘MIX BUS LINK’ connector.

The X-Rack Total Recall system allows session setups to be recalled instantly and can be archived as a

MIDI SysEx dump to any MIDI sequencer. The monitor section controls can also be controlled remotely

using MIDI controller commands from any MIDI controller. Up to three racks can be connected to an

AWS 900 or AWS 900+ and integrated with the AWS 900 Total Recall system via the serial port. Connecting

the MIX and REC outputs of the XR-622 to the MIX and REC Insert Returns of the AWS 900 and selecting

INSERT SUM mode allows almost unlimited expansion of the number of line level inputs to the console.

F.2 Connection

The rear panel of the module carries a pair of 25-way ‘D’ connectors. The left-hand

connector provides the main and alternate Monitor outputs as well as a stereo External

Input and the Mix Bus Insert Return. The right-hand connector provides Mix and

Record Bus outputs along with the Mix Bus Insert Send and a Follow-Monitor (pre-

level control) output.
All outputs (apart from the headphone output) operate at a nominal level of +4dBu

and are configured to drive standard line level inputs. Level compensation for feeding

600Ω inputs from the Bus, Insert and Monitor outputs is provided by removable

jumpers – refer to

Section F.3.4

for details.

F.3 Operation

As well as a compact stereo monitor section, the X-Rack Master module contains the

mix amps and outputs for the X-Rack’s internal Mix, Record and Solo/AFL busses.

The Mix bus is intended to be used as the main mix bus and includes a balanced

insert point immediately before the Mix level control. The Record bus provides a

direct path to a DAW (or any other recorder), allowing the Mix bus to be used to

provide a monitor mix while recording one or more inputs via the Record bus.
If the X-Rack is fitted with XR621 Mic Amp modules these can be routed directly to

the Record bus using the ‘REC L’ and ‘REC R’ switches on the XR621 module.

F.3.1 Mix Section

This section carries all of the Mix bus controls; the ‘MIX LEVEL’ control allows the

overall gain of the Mix bus to be adjusted (the Record bus level is fixed).
The ‘INS’ switch brings the Mix Bus Insert Return into circuit (the Insert Send is

permanently active) whilst the ‘SUM REC’ and ‘INS SUM’ switches allow the

Record bus and Insert Return to be summed with the Mix bus to allow for summing

of additional mix sources.
The ‘MON’ switch enables the Mix output to be replaced with whichever source(s)

have been selected for the Monitor section.
