The CP 64S is a versatile commercial preamplifier designed for use in restaurants, bars, health clubs and offices. The CP 64S is capable of serving two independent Zones. Two gated Paging inputs and four Program inputs are provided. Ports are provided for expansion of Page, Program or Zone signals. Four levels of priority are supported:
The versatility of the CP 64S allows a wide variety of system configurations while providing simple and intuitive controls.
Two gated Paging Inputs capable of receiving mic or line level input are provided. Each features independent Mic/Line Pad, Gain Trim, detector Threshold, Zone Assign and Zone Level controls. Internally selectable phantom power is provided for each input. Each Paging input may be summed Pre- or Post- Zone Level control to allow setting Paging Level independent of Zone Level. An internal Paging Priority switch allows a “master” pager to override non-priority paging in its assigned zones, while allowing true dual zone independent paging. If no Paging Priority is selected, the Paging inputs mix together for applications like karaoke.
Four stereo Program inputs are provided with independent Input Level controls. Any one of the four Program inputs may be independently assigned in each Zone. One of the Program inputs is a gated Priority Program input. When signal is detected at its input, it overrides any non-priority Program selection in the assigned Zones. The Priority detector features internal, adjustable Threshold and Release-Time controls.
The CP 64S has two Zone outputs: Zone 1 is stereo: Zone 2 is mono. Each Zone features independent:
Versatile wired remote control interface ports are provided for Paging assignment, Zone Level and Zone Program source selection. Paging Zone and Source/Volume remote controls are available as accessories.
Many options allow the installer to determine exactly which controls are employee accessible.The SCP 2S is an optional security cover for the CP 64S’s front panel EQ section. Any or all other front panel knobs can be removed and replaced with hole plugs -- six are included with the SCP 2S. Front panel Ducker Depth controls are screw driver adjust. The remote controls allow blank Decora™ plates to be remote control security covers. The remote knobs can also be individually replaced with hole plugs. For complete security, Rane carries the SC 17 single rack space security cover, only allowing the client access to the remote controls.
