Page 3: Preface
All the signal path stages are pure CLASS-A tubes circuitry and 3 transformers for each channel takes this uncompromising structure to the highest level of sonic excellence. I hope you will enjoy working with the Gainrider as much as we enjoyed making it for you! With Honor... -
Page 4: Front Panel Controls
Front Panel Controls 1. DC-T.H=DC-THRESHOLD: The input signal exceeded above this controlled threshold level goes into compression. 2. LOG-RATIO: Being a variable bias compressor means that the ratio of the signal being compressed gets higher with the amount of gain reduction. Therefore this knob adjusts the ratio’s slope angle (from soft compression - to hard limiting). -
Page 5: Signal Chain
Signal Chain This chapter details the signal chain structure in order to help you better understand the Gainrider capabilities. DUAL IN LEVEL: This is a variable input attenuator for both sides, ranging from -20db to 0db. It enables you to set compression amounts to both sides simultaneously or altering the amount of signal to drive into the Gainrider tubes. -
Page 6: Side Chain
We implemented the 0-300% scale on the CREST LEVEL knob in order to enable high levels of CREST material to mix with the RMS. In this instance, the Gainrider can generate a rhythmic effect caused by CREST signals taking control over the slow movements of the RMS material. -
Page 7: Rms Detector
RMS Detector In order to better understand the dynamic behavior of the Gainrider we need to understand the way it is developing Gain reduction in comparison to the input signals envelope. The above drawing shows an envelope of signal before compression (RED). -

Therefore the name Gainrider. The results of such mechanism are a much more natural and musical VCA’s behavior and with much more proximity then other tools. -
Page 9: Installation
4. Do not expose the unit to heat sources and unventilated places. Connections: All audio connections are transformer floating balanced through XLR connectors with the following pin list: PIN 1 PIN 2 PIN 3 COLD Signal Audio Workshop is not responsible for damages created by improper installation. -
Page 10: Maintenance & Calibration
Maintenance & Calibration Cleaning: Do not clean the unit with water or with water soaked cloth. Cleaning is best made with dry dusting brush and vacuum cleaner. Dust and moisture are the primer enemy of switches and contacts within this unit. Avoiding them as much as you can will prolong the unit’s life significantly. - Page 11 RATIO, CREST LEVEL, CREST RECOVERY: fully counter clockwise. IN LEVEL: set to 12:00 o’clock. ST-LINK: off. BYPASS: IN. Connect DVM between chassis ground and test point C-IN-A located on left of main board. Turn trimmers P1 and P2 located on S.C. pcb of channel A to get minimum readings TYPICAL READING -0.8V.
