- Page 2 Introduction This is the User Manual for the Stereo Ensemble SE330 module from Oakley Sound. This document contains an overview of the unit and goes into some detail regarding the operation of the module. It also contains the calibration instructions.
- Page 3 The Oakley Sound SE330 The Oakley SE330 is a 'mono in, stereo out' ensemble unit designed to mimic the behaviour of the multichannel chorus and ensemble units of late 1970s and early 1980s. The SE330 uses four channels of bucket brigade delay (BBD) lines and four voltage controlled low frequency oscillators (VC-LFO) to achieve a sound reminiscent of the Japanese string machines, guitar chorus pedals and studio rack effects of yesteryear.

Page 4: Input Level
Operating Instructions INPUT LEVEL The input level should be set so that the peak LED never lights continuously. The brighter the LED shines the more you are overdriving the unit and this is generally to be avoided. Ideally, the peak LED should never come on in normal operation. Once the input level is set to the correct point then the output level control can be adjusted to suit. -

SE330 does. It has three positions; dimension, stereo and quad. There are four bucket brigade delay lines in the SE330. Each side of the stereo signal has two dedicated BBDs and each BBD has its own driver circuitry which controls the delay imparted by the BBD. -

When listened to dry the overall effect is like an odd form of panning and vibrato at the same time. But when the balance pot is turned to around 50% a subtle chorus sound is heard. Stereo Ensemble Mode This mode is similar to the dimension mode but features four LFOs and not just two. Instead of the right hand BBD being modulated by the inverse of the same LFOs that control the left hand side, this time the right hand BBD gets its own pair of triangle and sinewave LFOs. -
Page 7: Input And Output Connections
Input and Output Connections The SE330 has both balanced input and output connections. It is expected that the unit will be fitted with three pole TRS (tip-ring-sleeve) sockets. Both input and output are compatible with unbalanced signals and mono jack plugs can be used without detriment to the SE330 It should work fine with signal levels direct from a mixer, line level synthesisers and modular synthesisers. - Page 8 Calibration There are sixteen trimmers on the SE330. It will be useful to have access to an oscilloscope and a frequency counter for the calibration routine, however, it is not necessary as most adjustments can be done with just your ears and a voltmeter.
- Page 9 Turn down both modulation depth pots and set the balance pot to wet. Select dimension mode. Listen to the left output of the SE330 only and adjust OFF2 so that the sound is not distorting. There will be a point at which the sound is not distorting noticeably while either side of it sounds thinner and grubbier.
- Page 10 S_FRQ This sets the frequency range of the sine wave LFOs. Insert an audio input into the SE330. The A440 note is a good one to use again. Set the sine rate and sine depth pot to their middle settings. Set the triangle wave depth pots to their minimum. Select the dimension mode and turn the balance control to wet.
