The AJH Synth Finaliser R-EQ comprises three separate sub modules that are perfect for adding that final touch to a modular synth patch.The REVERB section is an "old school" DSP reverb with seven reverb types, along with a fixed time delay function. The EQUALIZER section is fully analog with three parametric EQs, Bass Shelving and two ranges of high frequency shelving. The ENHANCER section is an analog, two band Maximizer/Enhancer circuit which alters the time and amplitude of signals to add punch, depth and brightness to a mix.

Analog Equalizer section

The Equalizer section is fully analog, based on inductor gyrator type circuitry. It features three parametric Equalizers with a massive ±24 dB range, with variable Q - which increases with frequency gain/attenuation. The parametric EQ bands cover the following ranges: LOW Band 25 Hz to 110 Hz, LO-MID Band 110 Hz to 700 Hz, and HI-MID Band 500 Hz to 2 kHz. The LOW Band also has a switch to select between peak and shelving EQ profiles. There is a fourth HIGH band, which again gives ±24 dB of gain, and this has switchable 2kHz or 5 kHz Shelving. The EQ section can be bypassed with the EQ-On switch, so it is quick and easy to hear the effect of the EQ profile compared to the untreated signal. The equalizer section is a Mono effect and works on the L/MONO Input only

Enhancer Section

The Enhancer/Maximizer section is a fully analog circuit which adjusts the phase/time shifting and amplitude on the treated signal to change the levels of fundamental and harmonics. The Enhancer/Maximizer was originally designed to correct phase and amplitude distortion in speaker systems, so that the resultant sound would more accurately recreate the source sound and correct for the time distortions introduced by speaker systems. However, they can and do go beyond the original brief and are often used as a creative effect to deliberately add punch, bite and extra clarity to source sounds. The ENH-Lo covers the lower band and the ENH-HI the higher bands, they are different from regular tone controls and EQ because, rather than just boost or attenuate particular frequency bands they are a very useful "finalizing" tool. The ENH-ON toggle switch is a bypass switch, so again it is very easy to have an a/b comparison against the untreated source sound. The Enhancer / Maximizer section of the Finaliser R-EQ is downstream of the equalizer section, so if the EQ and Enhancer are selected then the eq treated signal is fed to the Enhancer/Maximizer input.


Keep it simple was the philosophy AJH adopted with the reverb, no hunting through sub menus and tweaking hundreds of parameters, just seven switchable reverb types that can be selected using a rotary switch. Choose from Spring, Ambience, Room, Large Hall, Small Concert Hall, Large Concert Hall and Reverse profiles, along with a fixed time Delay setting. Very easy control of the wet/dry mix too - either manually with the reverb control knob, or by using a CV voltage patched into the REV-CV Input, in which case the Reverb control becomes an attenuator for this control voltage, so that it can accommodate a wider range of control voltages. With the reverb control fully clockwise a 0 to +5 V control voltage range will give full wet/dry control. The Reverb is the final module in the chain, so if the EQ and Enhancer/Maximizer are both switched in the signal flow on the L/Mono channel is EQ - ENH - Reverb.

The reverb can also be used as a Stereo IN/Stereo out effect by using the L/MONO and Right inputs. The EQ and Enhancer can still be used here, however they will only affect the L/Mono channel, the RIGHT channel will be reverb only.
