Oakley sound systems stereo ensemble – se330 pcb issue 2 user manual v2.0.3 tony allgood oakley sound systems carlisle united kingdom.
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. For the builder's guide, which contains a basic ...
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 osc...
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...
Sine rate controls the rate of the sine wave lfos. A sine wave is similar to the triangle wave but the rises and falls in output voltage are more gentle. The waveform is more akin to natural resonances slowing down before it changes direction. Sine depth controls the depth of the sine wave modulatio...
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 th...
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 se33...
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. All voltages should be measured with respect...
Off1, off2, off3 & off4 these adjust the bias point of the respective bbd line's input signal. If this voltage offset is set too high or too low then the output signal of that bbd will distort too easily. Input a triangle wave or smooth sounding tone into the se330. You can use a keyboard and hold d...
T_lvl this sets the maximum output level of both triangle wave lfos. Without a 'scope this is difficult to set exactly but it doesn't really matter that much. Simply adjust the trimmer to its middle position and you should find that the depth pot goes from nothing to all out freaky vibrato. If you d...
Final comments i hope you enjoy using the oakley sound se330. If you have any problems with the module, an excellent source of support is the oakley sound forum at muffwiggler.Com. If you have a comment about this user manual, or have a found a mistake in it, then please do let me know either via e-...
