AM8009 SH05 LFO's, S&H, NOISE

£150.00 inc. tax

This is module is a replica of the two LFO's, Noise, and Sample & Hold circuits in the Roland SH-5 monophonic synthesizer introduced in 1976. They provide the versatile modulation capabilities that this synthesizer is famous for, and form the left hand section of the main panel.

The AMSynths circuit is similar to the original and based around the same JFET's and UJT transistors, with 741 and 1458 IC's. LFO-1 is a basic affair with just a sawtooth and offset inverted sawtooth waveform. LFO-2 has a wider range of waveforms; triangle, square and sine (which can be delayed).

The Sample and Hold circuit is driven by its own internal clock (rate set by sample time) and it can sample either LFO-1 sawtooth, LFO-2 triangle or the Noise output. This approach enables the traditional random step waveforms as well as more predictable patterns.

There are LED indicators for the LFO rates;

LFO-1 red
LFO-2 red
S&H green

There are eight 3.5 mm jack sockets on the base of the front panel:

LFO-1 output
LFO-2 triangle
LFO-2 square
LFO-2 inverted square
LFO-2 sine with delay up to 4 seconds
White or Pink Noise
Trigger Output - LFO-2 or S&H Clock
Sample and Hold Output

NOTE 1: The panel has a label error. The Trigger Output is from LFO-2 not LFO-1.

NOTE 2: Please read the User Manual before purchasing so you are familar with the voltage levels the AM8009 generates, some have positive offsets.
