GC Audio Analog Riser User Manual
Thank you for purchasing the GC Audio Analgo Riser.
We hope you enjoy using it as much as we enjoyed designing it!
The GC Audio Analog Riser is a high-end dynamics and harmonics processor, which allows you to
obtain sharp and unique dynamics and harmonics processing. It offers a unique sound signature
for demanding engineers, right up to the mastering stage.
Several years of research and development have been necessary to create this analog processor
so that it can be used in all areas of the audio business.
An uncompromising electronic design has been made to obtain an irreproachable sound quality.
The GC Audio Analog Riser will allow you to process sound with confidence and pleasure for
recording, mixing and mastering.
The Analog Riser is a fully analog design built around 5 tubes, 4 VCAs, 4 Lundhal transformers, a
hundred low noise operational amplifiers, Grayhill switches, IP knobs, etc. Its powerful
combinations of harmonic processing / make up and MS mode make it a unique machine.
No signal goes through the front panel switches. About 40 relays ensure a routing as close as
possible to the motherboard.

Summary of Contents for GC audio Analog Riser

  • Page 1 The GC Audio Analog Riser will allow you to process sound with confidence and pleasure for recording, mixing and mastering. The Analog Riser is a fully analog design built around 5 tubes, 4 VCAs, 4 Lundhal transformers, a hundred low noise operational amplifiers, Grayhill switches, IP knobs, etc. Its powerful combinations of harmonic processing / make up and MS mode make it a unique machine.
  • Page 2 The Analog Riser offers 5 processing stages in one machine: 1) A 3-band full parametric equalizer with Low Cut and High Cut: Although the primary function of this EQ is to define a multiband contour for the compressor detection threshold, it can also be used as a stand-alone EQ.
  • Page 3 12AY7 lamps. The Analog Riser allows two types of make up: The discrete make up of the compressor stage which will have a very transparent rendering and the lamp make up which allows to color the signal, or even give it a saturation.
  • Page 4 The Analog Riser has 3 operating modes: 1) Mode Dual Mono Configuration A: All stages are active This is the default mode when you power on the. An analog processor with two completely independent channels. In this mode, you can simultaneously process two tracks independently.
  • Page 5: Stereo Mode

    To activate this mode, after powering up the machine, simply press the "M/S" button. This mode dedicated to mastering is a very powerful tool that allows a different dynamic treatment between what is mixed in the center (Mid) and what is mixed on the sides (Side).

  • Page 6 Confugration B : When all stages are active but the Compressor stage : The M/S function of the Analog Riser is very powerful. It allows new settings where it will be possible for example to make-up the tube gain on the sides and a discreet make-up on the middle.
  • Page 7: Technical Overview

    TECHNICAL OVERVIEW The Analog Riser has 3 operation modes 1) Dual Mono Mode: This is the default mode when you turn on the machine. It is a completely independent two channel analog processor. It is possible in this mode to simultaneously process two separate tracks in a mix.
  • Page 8 The M/S encoder and decoder of the Analog Riser is built around dedicated differential amplifiers with a laser engraved calibration which allows a very precise processing of the signal.
  • Page 9: Rack Mounting

    European wiring convention: Pin 1 = Ground, Pin 2 = Hot (+) Pin 3 = Cold. Power The GC Audio Analog Riser can be powered from either a 230V or 115V source via a switch on the rear panel. Please refer to the safety instructions.
