EQ1-S Features

All Tube,  Two channel Stereo, Hi-End Analogue design, from Input to Output

Fully Transformer balanced, switchable for unbalanced use

10 continuously variable (+/- 6db) wide EQ bands per channel, with stereo -tracking  controls, covering the whole audio spectrum and an overall frequency response of 5hz to 60Khz


The Heart of the EQ:

Supreme Flexibility – Its 10 continuously variable (+/- 6db) wide EQ bands and split channel format allows far greater control and variation of tonal structures, without losing vital audio information at surrounding frequencies of other instruments and control.The filter section uses precision inductors in a split signal path active tube circuit topology – two separate, full bandwidth EQ paths per channel.



Additional Stereo, continuously variable Contour controls for LF, MF/HF with two switchable centre frequencies with Left and Right output level trim controls.



An external, high voltage, high -headroom power supply provides ultra -dynamic transient delivery and a big wide soundstage, with each channel having its own HT and DC heater supply, for maximum stereo separation.

The DC Power Supply is connected via an umbilical cable using precision Swiss-made connectors, as shown here:


The EQ1-S uses only the highest quality matched vacuum tubes, 6 x 12AT7 and 4 x 6SN7.
Audiophile quality components throughout:
