The Input Gain control (ref. #10) provides from about +7 dB to +56 dB of gain for the preamplifier input stage.

Also remember, the energy and excitement generated during a perfor- mance guarantees that it will always be louder than the rehearsal, so after determining the gain during the sound-check it is a good idea to set the Input Gain control one or two clicks lower for the performance to allow yet a little more margin for headroom.
- Page 10 the general signal level. It is suggested to start with the Output Gain control in the one o’clock position for a setting near unity gain. Note, however, that if you subse- quently apply HF boost, you may need to reduce the Output Gain control correspondingly to avoid system overload.
- Page 11 Using the HF CurveShaper The RPQ500 features a unique CurveShaper circuit that enables you to add a little extra “presence” or “air” to the pickup to compensate for high-frequency losses that are inherent to most ribbon microphones, the result of distant mic placement, or an overly “dry” acoustical environ- ment.
