3.3.10 Dynamics Section (Expander & Gate Part)
For dynamics processing, an Expander/Gate function and a Limiter/Com-
pressor function can be configured. These functions can be switched
ON/OFF on the Channel Strip.
Notes: In addition, Expander and Gate can be switched ON/OFF individually. As
a result, the DYN–EXP/GTE key on the Channel Strip has no effect if both
have been switched OFF individually. Pages 3 and 4 (look-forward and
key control) are common to the entire dynamics section.
Dynamic Keying: The Key Source input can be selected from CHAN (dynamics processing
depends on the channel’s input signal) or PTCH (processing is controlled
by a signal connected via the patch). High- and low-pass filters are avail-
able for the side-chain (key source) path.
Dynamic Link: Several channels can be linked together, which means that a control signal
of the channel with the highest level will control all other channels.
Links are can be turned on and off from the LACP and are setup via the
Graphic Controller; refer to chapter 4.4.3.7).
GRM: Gain Reduction can be displayed on the channel meters. GRM is activated
on the Central Facilities Unit (CFU). This switchover affects only channels
configured with a Dynamics Unit. In GRM mode, the left bar on the Chan-
nel Meter indicates the level (for stereo channels, the higher-channel level
is shown), while the right bar indicates the current gain reduction produced
by the Dynamics Unit. In addition, a three- colour E/G LED, which dis-
plays dynamic unit activity, is included in the fader unit.
3.3.10.1 Assigning the Expander/Gate Section
A. Global Assignment:
• Press EXP/GATE on the Master Menu Selector. The displays of all
Channel Strips will switch over and indicate the Expander/Gate control
parameters, except those in FREEZE mode; see chapter 3.3.2.
• Press one of the PAGE 1 through 4 keys on the MMS to select the de-
sired parameters (PAGE 1 for Gate attenuation/on-off/attack/hystere-
sis/release/ threshold, PAGE 2 for Expander ratio/on-off/attack/release/
threshold, PAGE 3 for Look-forward, PAGE 4 for HPF/LPF/key in-
put/side-chain link on-off).
B. Local Assignment on the channel strip:
• Press ASN SEL; the ASN SEL key will flash.
• Press the DYN–EXP/GATE key.
• Press one of the PAGE 1 through 4 keys on the Channel Strip to select
the desired parameter.
C. Local Assignment affecting all channel strips:
• Press LINK ACCESS on the Master Menu Selector.
• Pressing a local assignment key will now affect all Channel Strips. The
same functions as described in “B” are available.
