Rane Music Pedal G4 Manual Do Utilizador

The Active / Bypass switch bypasses or activates dynamics 

processing for each channel. Side-chain metering and Listen 

continue to operate in Bypass. Bypass switches remain indepen-

dent in Link mode.

The G4 has three modes of operation: Gate, Ducker or down-

ward Expander. See the Operation section on page Manual-4 

for operation details of each mode.

In Gate mode, THRESHOLD sets the key level below which 

the Gate is closed.

In Expand mode, THRESHOLD sets the key level below 

which downward expansion takes place.

In Duck mode, THRESHOLD sets the key level above 

which the signal is ducked.

In Gate mode, ATTACK determines how quickly the Gate 

opens when the key signal goes above the set threshold.

In Expand mode, ATTACK determines the rate of gain in-

crease as the key signal moves toward or above the set threshold.

In Duck mode, ATTACK determines how quickly the 

signal is ducked as the key signal goes above threshold.

The  eleven-segment SIDE-CHAIN signal meter indicates 

level relative to the Threshold (dBr), allowing easy and intuitive 

adjustment of the Gate threshold. The Threshold indicator TH 

is lit whenever the filtered side-chain signal is at or above the 

set threshold. The signal peak value is held briefly to assist in 

setting a proper threshold.

Meter ballistics follow the response of the side-chain detec-

tor. Gate and Duck modes use peak detection with instanta-

neous attack and 25 ms decay. Expand mode uses rms detection 

with an averaging time constant of 50 ms. 

Gate status is shown using a seven-segment gain reduction/

gate meter. This meter is effectively an expanded version of the 

simple “stop light” meter found on many gates. The inclusion 

of gain reduction metering allows the user to view the transi-

tion progress of the Gate and Ducker as well as the current gain 

reduction when in Expand mode. The CLOSED LED is not ac-

tive in Expand mode. The response of the gain reduction meter 

accurately follows the Attack/Hold/Release envelope.

With this combined metering system it is possible to see at a 

glance where the signal level is in relation to the threshold, and 

the amount of gain reduction being applied.

Channels 1 and 2 may be Linked for stereo operation, as may 

channels 3 and 4. Channels 1 and 3 act as the Master when 

Linked, with channels 2 and 4 operating as Slaves to their 

respective Masters. When Linked, only the Master’s rotary 

controls and mode select switch are active. The Master controls 

the gain reduction of both channels.

Gate and Duck modes use look-ahead peak detection and 

the Master uses the larger of the two processed signals. In 

downward Expand mode, rms detection is used and the master 

uses the rms sum of the filtered side-chain signals. 

remain independent when channels are Linked. To trigger from 

only one key input, set the key source (INT/EXT) of the signal 

you wish to ignore to EXTernal and leave the rear panel side-

chain input disconnected.
