About this Operator’s Guide
Welcome to the Gray|328 and Gray 328|MXE digital audio mixers! The
Gray|328 and the Gray 328|MXE operations are exactly the same other
than the Gray 328|MXE includes the ability to transfer registers to and
from a USB memory device. This Operator’s Guide refers to all
operations as Gray|328 with the exception of the section pertaining to the
Gray 328|MXE memory management.
Note
For detailed installation information, for example how to add input or
output modules to your mixer, please consult the Installation Guide for
your specific mixer.
This Operator’s Guide covers the following subjects:
•Overviews
•Control Descriptions
•LCD View and Menu Descriptions
•System adjustments and Information Display
•Fader Assignments
•Applying Audio Effects
•Monitoring Control
•Memory Save/Recall
•ESAM II Control
•USB Register Management for Gray 328|MXE only.
This guide also includes an appendix containing some installation details
you may need to refer to from time to time.

Overview of the Gray|328 Mixer
Overview of the Gray|328
The Gray|328 digital audio mixer is designed for use in professional linear
video edit suites.
Note
The Gray|328 is a self-contained standalone mixer whereas the Gray
328|MXE has a separate audio engine chassis connected to a separate
Gray control panel via a Ethernet cable. All input and output functionality
is the same between the two products.
Inputs and Mixing
Optional input modules allow up to 32 audio inputs. Four slots on the
back of the mixer accept either analog (4 or 6 channel) or digital (8
channel) input modules, for a maximum of 32 channels. The mixer can
actively mix up to 6 channels of these inputs simultaneously, and send
them out over eight program output buses. Eight more program,
monitoring, or meter outputs can be added with an optional output
module.
Monitoring
The Gray|328 has eight monitor outputs and a headphone output. Any
combination of the program bus, solo bus, or record-returns can be
selected for listening on the monitor and/or headphone outputs. A built in
preview switcher provides automatic control of monitoring the program
bus and the record-returns on a channel by channel basis via edit system
control.
Loudness Monitoring
The M 6 includes the ability to monitor the loudness level of the audio
using using ITU-R BS. 770-2 gated algorithm. The Loudness Monitoring
can either follow the monitoring mode or a custom set-up can be created.
Display
An LCD display allows mixer configuration and signal characteristics to be
viewed. In addition, a unique, user-friendly system of menus and variable-
function buttons provides basic fader setup and extensive audio effects to
be applied. This system allows a great deal of functionality to be placed in
a small, space-saving console.
Feature Summary
•Accepts analog or digital audio.
Page 6 Overview of the Gray|328 Mixer

Operator’s Guide
•Digital inputs may be AES or SD/HD SDI (serial digital with embedded
audio).
•Accepts up to 32 input channels with optional input modules.
•Auto To/From allows access to all 32 input channels from the edit
system.
•Mixes 6 channels simultaneously.
•Has eight program outputs.
•Has eight highly configurable monitor and stereo headphone outputs.
•Has a built-in preview swticher.
•Loudness Monitoring using ITU-R BS. 770-2 gated algorithm.
•Optional output module can be added for additional program, monitor,
or meter outputs.
•Has powerful LCD menu system with space-saving variable-function
buttons for fader setup and applying audio effects.
About the Gray|328
The Gray|328 contains functionality that allows it to be controlled by an
edit system using the ESAM II protocol. An example of such a suite is
shown below.
Figure 1. Gray|328 in Editor-Controlled Video Edit Suite
Additional functions include the following:
•An RS422 interface for ESAM II editor control
Overview of the Gray|328 Mixer Page 7

Renegade Labs Gray|328
•Cut and transition (dissolve) capability
•Additional monitoring functions. Can monitor either program outputs,
record returns, or preview via solo mode.
•Ability to designate some inputs as record returns, independent of
faders, for monitoring the recorded mixer output.
•Full 8-bus preview functionality
•A Preset bus to designate which channels are transitioned TO during
cuts and transitions
•Auto Record handles VTR swapping from the edit system
The eight monitor outputs are controlled by a preview switcher that can
select either the mixer's program output buses or the unmodified record
return inputs for monitoring. The preview switcher also allows for a set of
inputs, configured at unity level and otherwise unmodified, to be used as
record returns that are independent of the faders. This allows fader
channels to be used entirely for mixing sources.
Under ESAM II control, a input pair is assigned an editor crosspoint
number. Each input pair can have an individual crosspoint number,
allowing for eight 2-channel sources; or multiple input pairs can be
assigned the same crosspoint number, allowing for 4-channel and/or 8-
channel source control.

Control Descriptions
Control Panel Overview
The control panel provides access to the many features of the mixer.
Intelligent software helps cut down on the number of button presses you
need to get the job done. Buttons with multiple functions expand the
mixer’s capability.
This section provides a quick look at the control panel of the Gray|328.
The sections that follow describe the controls in more detail.
