When gain staging in the OPUS architecture, the signal level at the input is a key factor to consider - especially when mitigating the impact of noise on your audio signal. The VU meters on OPUS’ OLED display indicate both the input and output levels of the device; to ensure optimal performance, the top bar graph (input level) should peak as high as possible without clipping. For output levelling, ensure all DSP-powered processing results in the output VU metering matching (or sitting slightly under) the input VU meter.
OPUS features a global INPUT PAD located within the GLOBAL menu - this setting is set to Off by default. This setting is a global parameter and as such impacts each and every preset; furthermore, it has been engineered to reduce the input level of the source audio before reaching OPUS’ audio DSP. The INPUT PAD is a technical corrective tool and not a creative tool. Before instantiating the INPUT PAD, it is important to first set the 3-way IN LEVEL switch to match the nature of the input source:
If after setting the 3-way IN LEVEL switch - correctly in accordance with your signal requirements - OPUS displays a clipping signal , please then use the INPUT PAD to further attenuate your source signal.
When a dry/unprocessed signal passes into the OPUS, there are a number of points in the processing signal chain where levels can be raised:
