OBERHEIM GM 1000
Digital Signal Processor
- 115 -
Manual parameter. Range: 0 - 100
Determines the point where operation of the filter starts. The operating mode is different
for automatic and pedal wah.
Peak parameter. Range: 1 - 10
The parameter influences the form of the wah filter, accentuating or reducing its
resonance.
Sensitivity parameter. Range: 0 - 100
Regulates the sensitivity of the wah filter to variations in the control. With sensitivity zero
no effect is obtained, while with sensitivity at the maximum setting the filter open/closing
range is the maximum possible.
Level parameter. Range: 0 - 100
Regulates the level of the output signal in the context of the effects chain.
COMB FILTER
This is a comb filter with two lines, which provide two resonance frequency patterns. It is
the equivalent of a flanger with its modulation locked on one setting. Since the parameters
in the 2 lines are identical, they will be described together.
Frequency 1 and Frequency 2 parameters. Range 0 - 100
They set the resonance frequency for each line.
Feedback 1 and Feedback 2 parameters. Range: -100 - +100
They regulate the entity of the resonances by varying the feedback values of the two lines.
Hi Damp 1 and Hi Damp 2 parameters. Range: 1K, 2K, 4K, 5K05, 6K35, 8K, 9K, 10K,
11K5, 12K5, 14K5, 16K, 17K, 18K, 19K, 20K, None.
These settings attenuate the high frequencies by means of two separate filters for each
line, establishing their cut-off frequency.
Mix 1 and Mix 2 parameters. Range: -100 - +100
