User manual RANE CP 31

[. . . ] PROGRAM INPUTS: Connect line level program sources to the RCA PROGRAM INPUT jacks and engage the MONO switch if desired. EXPAND OUTPUT: Wire the EXPAND Output Euroblock as required to a mono feed delivering PAGE-only or PROGRAM-only signal, depending on the rear panel switch setting. This Output uses a line driver that may be used balanced or unbalanced. Adjust the EXPAND LEVEL trim as desired. [. . . ] PAGING OL (Overload) indicator lights when the Page Input preamplifier comes within 4 dB of clipping. ACTIVE indicator lights when the Page signal level reaches the Paging Detect Threshold. Note that a Page is always Active when the PAGING DETECT THRESHOLD is set to minimum (ccw). PAGING ASSIGN switch selects whether the Page signal is sent to Zone A, Zone B, BOTH Zones, or OFF (no Zones). PAGING LEVEL controls adjust the Paging Level in each of the two (A & B) Zones. PROGRAM INPUT LEVEL controls allow independent level adjustment for the stereo or dual mono Program Input(s). ZONE DUCKER DEPTH control sets the Ducker Depth (the amount of Program attenuation during a Page) from 50 dB (ccw) to 6 dB (cw). The Ducker release is ramped and not user-adjustable. ZONE DUCKER OFF/ON switches independently turn each Ducker ON or OFF. ZONE Output Meter displays PEAK signal levels at -10 dBu, +4 dBu, and +16 dBu. ZONE LEVEL controls adjust the overall Level for each Zone Output. This concentric pot allows independent adjustment of Output Levels, or "stereo/master" level control by holding both the inner and outer knobs together. PWR indicator lights when the CP 31 is connected to a powered RS 1 power supply. Manual-2 CP 31 - REAR PANEL Chassis Ground Screw provides a convenient earth (technical) ground connection point. The CP 31 does not ground the chassis through the power cord. It is important that the unit be grounded (required by law in most installations). POWER jack accepts the mod plug from a Rane RS 1 remote power supply (included) or an optional Rane RAP 10 power supply. Use of a supply not approved by Rane may damage the unit and void the warranty. ZONE OUTPUT Port features a balanced line driver with a Euroblock connector. These Left and Right Outputs may be wired balanced or unbalanced. EXPAND OUTPUT Port features a balanced line driver with a Euroblock connector. This mono Output may be wired balanced or unbalanced. EXPAND OUTPUT switch assigns PAGE-only or PROGRAM-only as the source for the Expand Output. [. . . ] Speak into the Paging mic in a normal voice and adjust the Paging DETECT THRESHOLD so the ACTIVE indicator lights only during speech. If the Paging DETECT THRESHOLD is set too low, the Pager may gate on due to background sound. With a Program source playing, speak into the Paging mic. Adjust the Paging LEVEL control to provide the correct Page-toProgram mix. [. . . ]
