User Guide
Reverb, Equaliser and Sonic Enhancer
Thank you for purchasing the AJH Synth FINALISER REQ module, which like all AJH Synth
Modules, has been designed and handbuilt in the UK from the very highest quality components.
We hope that it will help and inspire you towards creating some great music and soundscapes!
Designed to be the last link in the Eurorack signal chain, a module that can apply parametric
equalisation, maximiser / exciter and reverb to add that " nishing touch" to your Eurorack patch.
It is primarily a Mono in, Mono out or Mono In, Stereo out device that can apply Stereo reverb to
Mono Source signals. It will also work as a Stereo IN / Stereo out module too, however in this case
the Equaliser and Enhancer can only be applied to the Left audio channel.
The fully analogue four band Equaliser includes three paramentric equalisers for Low, Low Mid
and High Mid ranges, and the High EQ has switchable shelving of either 2kHz or 5kHz.. The Low
EQ also includes a useful shelving mode.
The Maximiser is a fully analogue circuit too, with low and high treatment bands which change
the phase and amplitude relationships of the sound to add punch and harmonics and really bring
the sound to life in the mix.
The Reverb engine is based on 20 year old DSP technology, harking back to the reverb units
which were used extensively on many synth and EDM tracks a couple of decades ago. It includes
eight di erent e ects and includes full control of reverb wet / dry mix, either manually or under
CV control.
Module width is 18 HP of Eurorack space and it is compatible with standard Eurorack cases. The
height of the panel is 128.5mm and depth is 24mm . There are four mounting holes at the
corners of the module and we provide 4 of M3 rack xing screws along with a Eurorack
compatible power cable. Current consumption is 105mA from the +12V supply rail and 55mA
from the -12V supply rail.
All AJHSynth modules are covered by a two year guarantee against manufacturing defects.
Note:
It is very important that the power supply ribbon cable is connected correctly, see the "adjustment and
calibration" section for an illustration of the correct orientation.

- Page 2 Overview The Finaliser REQ has been designed to be the last module in the signal chain and add some professional “polish” to your patch, and comprises three separate sub modules: 1 - A fully analogue, four channel equaliser: Three of the channels (Low, Low Mid, High Mid) have parametric equalisation, i.e. it is possible to select the centre frequency of the equaliser, and then add up to 24dB of variable Q boost or cut around the selected frequency.

- Page 4 Sets the response for the LOW parametric equaliser, with the SHELF switch up the EQ is in 8 SHELF : standard “peak” mode, with the SHELF switch down the Shelf Low frequency mode is active. 9 L/MONO IN : Left Audio INPUT. Signals fed into this input can be routed to the Equaliser and Enhancer sections, which are mono only.
- Page 5 FINALISER R-EQ - PATCHING EXAMPLES Two voices patched in Stereo in / Stereo out Mode In this patch we are using the Finaliser R-EQ in Stereo In / Stereo out mode. We have two independent synth voices, both voices are patched into the Gemini 2412 Dual VCF, however it is being used as two independent VCF’s here.
- Page 6 FINALISER R-EQ - PATCHING EXAMPLES 3 VCO Plus dualSubBass patch - Mono in / Stereo out Mode Here we are using the Finaliser in Mono in / Mono Out Mode, with the Equaliser and Enhancer engaged. The Finaliser is used to add some reverb and a little EQ and enhancement to what is a very fat sounding patch, there are three VCO’s fed into the Ring SM Module, which is used as a mixer (Inputs 1, 2 and 3) but we have also patched in the Ramp wave from VCO to the Ring SM “X”...
- Page 7 FINALISER REQ - Speci cation Description: Analogue four channel Equaliser, two channel analogue Sonic Enhancer and Stereo Reverb Eurorack signal processing module. Dimensions: 18HP x 3U Eurorack, 91.3mm x 128.5mm Power usage: +12V, -12V 10 pin Eurorack power header. Reverse polarity protection is built in.
- Page 8 Adjustment and Calibration Important note: The Gemini 2412 module is calibrated after manufacture and under normal circumstances should not require any user adjustment. Trimmers not documented are for manufacturer’s use only and have tamper paint over the adjuster. We will not accept any modules returned for repair under warranty because the module has been incorrectly adjusted by users, to correct this and bring the unit back to full working order full calibration will be required, this is a fairly lengthy process and in this case will be a chargeable service.
