Demeter

The sound of classic studio optical compression of the 60's and 70's at your feet! The first compressor pedal not to suck the life out of your tone.

Operation
Operation is fairly straightforward. There are two inputs on the front side of the unit: a 1/4" input jack on the right and a 1/4" output jack on the left with a battery-ground switch on the input jack.

Controls
There are two controls on the unit: Compress and Volume, plus a foot switch to bypass the effect, and an LED to indicate effect operation. On the side there is a trim pot to set the overall gain of the unit.

Compress affects the amount of Gain reduction (compression) of the input signal. Turning this clockwise will give you up to 30dB of gain reduction (depending on input gain). Please note that the Compulator's max gain is 26dB (SEE Trim Pot) so in some circumstances if your instrument is very hot you could achieve less than unity gain if you turn up the compress knob too much.

Volume increases and decreases the output volume of the Compulator. Use this for level matching between the affected and unaffected signal.

Trim Pot sets the gain of the compressor's pre-amplifier. If distortion occurs turn this down until the signal is clean. The unit is set at the factory at 20dB of gain which is perfect for most instruments. If you have weaker pickups or want to push the envelope turn it up to its max gain of 26dB.

Power Supply is 9 volts DC. Either internal using a 9 volt battery (remove the four screws on the sides of the unit and pull apart), or external using a mini plug, Tip positive. External supplies should be regulated. 

A hybrid of vintage sound and state-of-the-art quality, the Demeter Tremulator is designed for years of trouble-free operation.

Designed to emulate the classic Fender tremolo effect (or vibrato as it is often referred to), the Tremulator features "lopsided" amplitude modulation with a rounded off triangular modulant waveform. Suffice it to say, the Tremulator sounds like the classic effect found on many vintage amps, but with less noise and hum and a greater range of speeds and depths.

Operation
Operation is fairly straightforward. There are two inputs on the front side of the unit: a 1/4" input jack on the right and a 1/4" output jack on the left with a battery-ground switch on the input jack.

Controls
There are two controls on the unit: Depth and Speed, plus a footswitch to bypass the effect, and an LED to indicate effect operation.

Depth affects the amount of amplitude modulation on the signal or the amount of effect. The tremulator design incorporates a small amount of gain (approx. 1dB) to allow for proper "tremulation." Also, by turning the DEPTH all the way off, the TRM-1 will function as a low noise volume boost. Its low-impedance output allows it to act as a line-drive, eliminating signal loss on long cable runs.

Speed increases and decreases the frequency of the low-frequency oscillator, enabling you to time the effect as desired.
