Next Generation FET Compressor with digital
recall
FET compressors have been an essential tool in recording studios for over 50 years. Its
distinctive sound and reliability have made it a go-to for producers and engineers around
the world. The 76-style FET compressor has left its mark on countless hit records which has
helped to establish its reputation as a reliable and versatile tool in recording technology.
We have improved this design, creating a whole new level of versatility with seamless DAW
integration - We present ng76 - fully analog FET compressor with digital recall.

1.Main Features
True ANALOG sound with extremely convenient control!
Full Total Recall and plugin control, compatible with most DAWs.
100% analog FET mono compressor with 24dBu of headroom.
Classic lightning speed compression style based on WesAudio Beta76 design.
Classic controls known from FET style compressor - INPUT / OUTPUT / ATTACK / RELEASE.
Additional MIX knob for parallel compression.
Carnhill Transformers (input and output).
Saturation mode - Special mode where static compression is triggered to produce
sonics based on FET circuit, and One knob which sets INPUT and OUTPUT in an opposite
way. It allows to use the unit as a saturation box / clipper.
Four ratio settings 4:1 / 8:1 / 12:1 / 20:1 - all possible combinations including ALL button
mode!
Modern and Vintage modes to support two 1176 revisions (F & G):
•Vintage - transformer balanced input,
•Modern - Electronically balanced input.
Features a sophisticated side chain circuit EQ with two independent sections:
•HPF 60 Hz / 90 Hz / 150 Hz - to maintain low end information while
compressing,
•High Shelf of 2kHz / 5kHz, 10kHz - to tame high frequencies by emphasizing
high/high mid-range content.
Vintage gain reduction meter.
Very precise INPUT and OUTPUT metering.
Hardware A/B buttons to compare two independent settings.
THD - total harmonic distortion with LOW and HIGH settings, based on the FET circuit.
Fully digitally controlled and isolated analog circuit.
ANALOG AUTOMATION in DAW.
Ethernet and USB connectivity for integration with digital plug-in.
Size: 2U.

2.Stereo Pairs
Ng76 is available in stereo pairs, each pair is carefully calibrated in the factory for stereo
usage –of course it still can be used either as dual mono independent compressors or one
stereo unit:
•Includes 2 separate mono-channel devices that can be linked together through
dedicated software.
•Compression detectors can be linked for true stereo compression using dedicated
cable (included).
•All parameters between units can be linked via a dedicated plug-in –change on
one channel triggers update on the other channel.
3.Hardware
This chapter explains all physical aspects of ng76 unit.

3.2. Front panel
1. Input –Determines the level of the input signal entering the compressor.
2. Output –Determines the level of the output signal leaving the compressor. It is used to
recover signal level affected by gain reduction in compression circuit.
3. H-LINK LED –indicates state of host-module connection.
4. Attack –It sets the Attack time from 20 microseconds to 800 microseconds. The attack time is
fastest when the Attack knob is in fully clockwise position, and its slowest when it’s in its fully
counterclockwise position.
5. Release –It sets the Release time from 50 milliseconds to 1100 milliseconds. The release time is
fastest when Release knob is in its fully clockwise position and is slowest when it is in its fully
counterclockwise position.

6. DATA LED –indicates that data is being sent from HOST to the device.
7. MIX –WET/DRY signal mixer knob. Allows the parallel compression to be used.
8. SC Filter EQ/ SC Link –There are two functions for this knob:
a. Pushing the knob toggles sidechain detector LINK on and off when two units are
linked via back TRS sockets.
b. Rotary encoder allows to select EQ in the side chain circuit:
i. First 6 position engages separate EQ sections,
ii. Moving further right compressor will start to select various combinations.
9. Saturation mode –Enables/Disables saturation mode. Please note when saturation mode is
engaged, sidechain filters, attack, release, ratio controls are disabled and don’t have any
effect.
10. A–internal preset memory buttons which can be used to compare two different compressor
settings.
11. INPUT MODE –toggles between VINTATE and MODERN modes INPUT modes (electronically
balanced vs transformer balanced input stage).
12. BYPASS –True bypass.
13. THD –Total Harmonic Distortion –Possible options: OFF/LOW/HIGH.
14. B–internal preset memory buttons which can be used to compare two different compressor
settings.
15. VU IN Metering –INPUT metering before any processing (-10dBu to 24dBu).
16. Gain reduction meter –This meter shows gain reduction (please note that this meter is
disabled when Saturation Mode is engaged).
17. VU OUTPUT Metering –OUTPUT metering (-10dBu to 24dBu).
18. Ratio - The Ratio button controls the depth of the compression, with a ratio of 4:1 being the
lowest possible compression value and 20:1 being the highest. Additionally, you have the
option to disable the ratio to disengage compression and enable any combination of ratios
you prefer. To activate more than one ratio (e.g., pressing the All button IN!), you can either
press all the ratios at the same time or press one ratio and then press and hold while
engaging the others you want.
19. POWER Button –Power switch.

3.3. Rear panel
1. Voltage selector –selection between 115V (60Hz) and 230V (50Hz). Please check Fuse
holder description before switching.
2. AC socket
3. Fuse holder –The fuse holder contains two fuses - one is currently in use, while the other
one is a spare. If, for any reason, your unit fails to power up, it is recommended to swap
the fuses and check if this resolves the issue.
IMPORTANT NOTE: each voltage standard has different fuse type:
a. 115V –T630mA
b. 230V –T315mA.
