XR622 X-Rack Master Module User’s Guide

This documentation package contains the User’s Guide for your new X-Rack Master module. Depending on the age of your X-Rack, these pages may already be present in your X-Rack Owner’s Manual – please check to see if these pages match your Manual. If they do not, these pages should be filed alongside it.

Please Note. The XR622 X-Rack Master module operates in conjunction with the XR625 X-Rack Mic Amp

and XR623 X-Rack Line Return modules.

X-Rack units prior to serial number XRK0110 are compatible with the X-Rack Master module but may require a small modification to the buscard; if the ‘SOLO’ LED is permanently illuminated, resistors R1 and R2 will need removing. In addition, any Mic Amp or Line Return module(s) must be fitted immediately to the left of the Master module – later X-Rack units do not have this limitation and modules may be freely placed anywhere in the later X-Rack units.

For correct operation of this module, your X-Rack unit must be running V1.2/0 or later software. Please refer to your X-Rack Owners Manual for instructions on how to check the current software version and how to obtain and install a newer version if required.

There may be a newer version of the X-Rack Owner’s Manual available for download from our website (www.solid-state-logic.com

F. 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.

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 XR622 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 (prelevel control) output.

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.

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.
