Useless output levels (1/10th of normal eurorack levels)
I bought this for use in my modular synth. On the surface it is a great oscillator for a bargain price. However, there is a caveat: The main waveform output levels are next to useless.
Raeson: The 4 main oscillators output levels are only -4dBu (0.48V rms). That is roughly equal to consumer level audio output (only 1/10th of normal eurorack levels). The aux output has a variable level and can output up to +/- 5V or rougly +16 dBu which is fine.
The low output level for the main waveforms means that you need to amplify these outputs by 20db to use them in your eurorack where 5V is the standard.
In practice what happens is that when using this module together with other oscillators and modules that output +/- 5V - the signal from the 921 is completely drowned out (unless they are amplified first - which is downright silly). Hence the only part of the oscillator you can really use is the aux output.
Ultimately I found this unacceptable and a waste of precious rack space and have returned the module. I am very sorry about that, because I loved the concept. Behringer: please fix this stupid design flaw.
