Specifications
Specification - Classic
VCO Panel
12 x Analogue VCOs. The pitch range is very high and these can be used as LFOs also.
Four waveforms, Pulse Width, Osc Sync, Sub Osc.
Precision control using high quality multi-turn vernier dials.
Sample and Hold Generator.
Random Voltage Generator.
2x White/Pink Noise Generators.
Multiple.
Scope Panel
Oscilloscope. Type may vary from pictures.
2x LFO (in addition to the VCOs).
4x VCA (in addition to the VCF VCAs).
4x A(D)SR Envelopes.
Multiple.
Note!
VCOs can be used as LFOs. So Colossus has in fact a potential total of 14 LFOs!
Each of the eight VCFs have VCAs hard wired inline, so these plus the individual VCAs means there are in fact a total of 12 VCAs!
Filter Panel
4x Multimode filters - Low, Band and High pass 12dB filters.
Each with serial VCAs.
The circuit was originally based on the Oberheim SEM - though we have done some heavy modifications. But ‘Oberheim SEM’ gives you an idea of the type of sound.
4x Low Pass filter - 24dB transistor ladder filters.
These filters have a ‘Moog’ style sound.
Each VCF has a serial VCA.
(8 VCF/VCA combinations in total.)
2x Analogue mechanical Spring Reverbs. Each one features a triple spring tank.
2x Ring Modulators.
2 Voltage Slew Generators.
4x ADSRs with repeat and hold-repeat feature.
Sequencer Panel
4x large 10V signal level meters that are backlit.
64 step / 2x 32 step Analogue CV/Gate sequencer.
With clock generator, glide, jump, reset, CV, gate and other control features.
10 input stereo Mixer
2 fixed level sub mixers
2x Joystick Controllers.
Matrices
2x Broadcast quality CV and Audio Pin Matrix panels.
Jack Socket Patch Panels
4x minijack patch panels - providing I/O from all circuits.
Rear Panel
Mixer output jacks; Left and Right.
IEC power socket.
Neon lit power switch.
Fuse holder.

Physical Specification
Size:
Classic : 1585mm width, 700mm depth, 655mm high.
Slim : 1585mm width, 330cm depth, 750mm high.
Note, if Classic is tilted 45 degrees the synth’s effective width reduces to 620mm which may help with unusually narrow doors. There are other tips for narrow doors in the text earlier in this manual.
Weight:
Classic : 55Kg. Slim : 40Kg.
Packing Crate is approximately 90Kg (excluding Colossus).
Power:
Switchable 115/230V (ask how if necessary!)
Note: If you have a CRT Oscilloscope, then this is NOT switchable.
You would need to convert the voltage. Disconnect power to the scope if you need to change the power voltage.
Note2: Some more recent CRTs are switchable - check the back panel of the scope to check.
For LCD scopes there is no problem.
IEC power socket with Neon mains switch.
Jack Sockets:
Use 3.5mm mono ‘mini jack’ cables.
There are two main out jack sockets that are mono/un-balanced 6.35mm ‘big’ jack. These are also copied to the rear panel.
Pins
These are not compatible with either Vostok or EMS matrices. Suggestion is to order direct from Analogue Solutions.
Two types are available -
Black 0 Ohm (best price)
Red 10K Ohm (expensive!)
Accessories
Comes with a selection of pins and cables.
IEC mains cable.
Additional parts are available to order, including (subject to stock) spare CRT oscilloscopes if you require a spare, cables, additional pins, LED CV cables, and more.
