 Allen
& Heath GL4800 Series
Frame sizes 24, 32, 40 and 48
The Allen&Heath GL4800 is a truly multifunctional console, offering
features such as group output trims for recording, extended auxiliaries
using matrix sends, multiple main outputs and trimmable direct outputs
from channels. The GL4800 is also a true workhorse: classic Allen&Heath
sound with a new mix head amp design, EQ section from the respected ML4000
and with solid construction, expandable frame design and an array of channel
format options - it's the Swiss Army Knife of mixers.
Multi-Function Mixing
The GL4800 can easily meet any live mixing requirement. A host of recessed
mode switches quickly configure the console for FOH, monitor or monitors
from FOH, with additional multitrack and stereo recording capability.
As a monitor console, you get up to 16 mixes for wedges, IEM and side
fills using the 10 auxes, 4 matrix and LR. No professional monitor console
is complete without an engineer's wedge output. The GL4800 provides this
by switching AFL/PFL to the M fader, giving familiar control in the right
place and with XLR drive.
Recording
Recording a live show can be particularly challenging, but the GL4800
has many options to make this job easier. You can use the direct output
with pre/post selection and level trim from each channel for multitracking.
The unique pre/post selectable group output trim facility allows grouped
signals to be fed pre the master fader so that changes to the mix do not
affect the record levels, particularly useful when trying to record and
mix noisy backlines. The 4 matrix and additional pre/post selectable LR2
outputs can also be used to feed the recording.
Matrix
The flexibility and benefits of a matrix cannot be under estimated in
today's console applications. The GL4800 excels with 4 matrix outputs,
with a useful mode to allow an insert and balanced XLR output to be swapped
from an aux if processing and long cable drive are needed. The matrix
mix can even be added to an aux mix if required, ideal for providing quick
monitor mixes from groups or LRM while lifting key inputs using channel
sends, or for adding effects to grouped signals.
Automation
A built-in processor manages the onboard mute system. 8 Quick select buttons
can be programmed as mute groups or instant recall scenes. 128 memories
can store snapshots of the channel and master mutes for scene recall,
with MIDI port to interface with show control or archiving systems, and
preview and safes functions to keep you in control. The processor also
lets you quickly set or clear all mutes with a single button press.
Engineer's Toolbox
In true Swiss Army Knife fashion, there is an abundance of tools to help
deal with every situation. The GL4800 master section is bristling with
recessed mode switches to help get the most from the console in any application.
A comprehensive monitoring system is provided with stereo PFL, PFL trim,
AFL, LED meters on every channel and mix bus, additional VU output meters,
local and headphone outputs, and Solo-in-Place which lets you listen to
the contribution of one or more channels in the mix, complete with toggle
last and safes functions. Talkback allows independent communication to
preselected outputs. A dedicated 2-track input is available for background
music playback. The stereo channels feature our innovative 4-point width
control which lets you narrow, reverse, mono or enhance your stereo image.
You can also work with stereo microphones by cross-patching between channels,
to use dedicated stereo coincident X-Y, spaced or M-S techniques. And
just to complete the functionality of the main outputs, LR blend to Mono
controls are provided to create a quick center fill mix.
Frame sizes include 24, 32, 40 and 48. You can order the GL4800 in one
of four mono/stereo channel combinations:
A = All mono channels
B = 4 stereo channels to right of masters
C = 4 stereo channels on far right hand side
D = 8 stereo channel on far right hand side
