Dynamics Plug-ins

Buss Comp 369

Buss Comp 369 emulates the bus compressor that has been used as the standard in recording studios and by broadcasters since the 1980s. In contrast to Compressor 276, which excels at creating aggressive compression sounds, it features smooth, natural compression that does not impair the expressiveness of the source.
It has both a built-in compressor and limiter, which can be used separately or in combination depending on the application. In addition, the rich harmonics of the input/output circuit audio transformer and discrete class A amplifier add depth and cohesiveness to the sound quality.
This plug-in operates in mono or stereo mode, depending on the channel configuration of the rack.

[INPUT ADJUST] Knob

Adjusts the input gain. However, the output gain changes in the opposite direction so that the passing volume (volume when [COMP IN] and [LIMIT IN] are off) does not change. For example, when [INPUT ADJUST] is +5 dB, the input gain is +5 dB and the output gain is -5 dB.

How INPUT ADJUST Works

input adjust en

Since the threshold changes substantially, the displayed value changes in tandem. However, the internal state of the COMPRESSOR/LIMITER SECTION does not change.

[LINK] Switch (in stereo mode)

Activates/Deactivates the stereo link.

COMP [IN] Switch

Activates/Deactivates the compressor.

COMP [THRESHOLD] Knob

Sets the threshold for the compressor. However, the value changes in conjunction with [INPUT ADJUST].

COMP [RECOVERY] Knob

Sets the release time of the compressor. The release time of a1 (auto 1) and a2 (auto 2) changes automatically.
a1 : Changes automatically between 100 ms and 2 sec.
a2 : Changes automatically between 50 ms and 5 sec.

COMP [GAIN] Knob

Sets the make-up gain of the compressor. It works in front of the limiter.

COMP [RATIO] Knob

Adjust the ratio of the compressor.

[METER] Select Switch (in stereo mode)

Selects the signal source for the meters. You can select from three options: IN (input level), GR (gain reduction), and OUT (output level). When you switch the signal source, the meter design (VU/GR/VU) also changes.

[VU] Select Switch (in mono mode)

Selects the signal source for the VU meter. You can select either input level or output level.

LIMIT [IN] Switch

Activates/Deactivates the limiter.

LIMIT [ATTACK] Switch

Sets the attack time of the limiter.
FAST: 2 ms
SLOW: 4 ms

LIMIT [THRESHOLD] Knob

Sets the threshold for the limiter. However, the value changes in conjunction with [INPUT ADJUST].

LIMIT [RECOVERY] Knob

Sets the release time of the limiter. The release time of a1 (auto 1) and a2 (auto 2) changes automatically.
a1 : Changes automatically between 100 ms and 2 sec.
a2 : Changes automatically between 50 ms and 5 sec.

Compressor 260

Compressor 260 emulates the characteristics of a compressor and limiter that were widely used in the mid-1970s.
This plug-in operates in mono or stereo mode, depending on the channel configuration of the rack.

[THRESHOLD] Knob

Sets the level at which compression is applied. Only signal levels that are above the set threshold are processed.

[KNEE] Switch

Sets how fast compression is applied. When set to [SOFT], the compression ratio increases slowly as the level increases, and when set to [HARD] it is compressed immediately.

[ATTACK] Knob

Sets the time it takes for Compressor 260 to respond to a signal level that is above the threshold. The longer the [ATTACK] time, the greater the amount of signal (attack) that passes unprocessed.

[RELEASE] Knob

Sets the time it takes for the gain to return to the original level when the signal drops below the threshold.

[RATIO] Knob

Adjust the ratio. Turn the control to the right to increase the compression ratio. If you turn it completely to the right, the plug-in will operate as a limiter.

[OUTPUT] Knob

Adjusts the output gain.

[GR] Meter

Displays the amount of gain reduction applied by the plug-in.

[OUT] Meter

Displays the output level of the effect.

Compressor 276

Compressor 276 emulates the characteristics of an analog compressor that is a staple in recording studios. You can obtain thick, strong sounds that are suitable for drums and bass parts.
This plug-in operates in mono or stereo mode, depending on the channel configuration of the rack.

comp276
[INPUT] Knob

Adjusts the input level.

[RATIO] Knob

Adjust the ratio of the compressor.

[ATTACK] Knob

Adjusts the attack time of the compressor.

[OUTPUT] Knob

Adjusts the output gain.

[AUTO MAKEUP] Switch

When activated, it automatically compensates for the drop in output gain when the compressor is applied.

[INTERNAL SC HPF] Switch

When activated, less compression is applied to the low frequencies so that the low frequencies are emphasized.

[RELEASE] Knob

Adjusts the release time of the compressor.

[VU] Meter

Displays the signal that is selected with the [GR]/[-10]/[-20]/[OFF] switch.

[GR]/[-10]/[-20]/[OFF] Switch

Selects the signal that is monitored by the VU meter.
GR : Displays the amount of gain reduction.
-10 : Displays the signal with 0VU as -10 dBu.
-20 : Displays the signal with 0VU as -20 dBu.
OFF : Deactivates the VU meter.

MBC4

This high-quality four-band compressor utilizes VCM technology and features a GUI that offers outstanding operability and visibility. All advantages of the musical behavior of analog compressors have been built into the gain reduction circuitry of the MBC4, allowing smooth control of dynamics while retaining the overall image of the original sound. The sound image can also be visually manipulated via a graphical display.
