CP 64S Commercial Processor

General Description

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:

• Priority Page
• Non-Priority Page
• Priority Program
• Non-Priority Program

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:

• Level
• Program Select
• Ducker On/Off
• Ducker Depth
• Servo-Locked-Limiter™
• 7 Band EQ (±12 dB)

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.

The CP 64S improves upon the CP 64 with a universal voltage internal power supply. All other features are identical. See the CP 52S if you only need one page input and one main zone. See the DA 26S if you need up to 6 zones.

PR 2 and ZR 1 Remote Accessories

Two optional wired remote control units are available. The PR 2 allows remote control of Page 1 and Page 2 Zone Assign selection. The ZR 1 allows remote control of Zone Level and Zone Program selection. One PR 2 and two ZR 1 remotes may be used with each CP 64S. The PR 2 and ZR 1 may be installed in standard electrical boxes (minimum depth 2.25"). The remotes connect to the CP 64S through 5-pin Euroblock connectors.

The PR 2 is a 5-wire remote with 2 bits to select Page 1 Assign, one wire for shield/ground and 2 bits for Page 2 Assign. Selector logic is active low BCD with pull-up provided in the CP 64S. Control may be a simple switch closure to ground or 5 volt TTL. Page 1 and Page 2 bits may be paralleled so that one switch controls both Page Assigns. Remote control is initiated by setting the front panel Paging Zone Assign selector to RMT.

The ZR 1 is a 5-wire remote with 2 bits for Zone Program selection (active low Gray Code), a common shield/ground and two wires for ratiometric DC control of Zone Level. Zone 1 and Zone 2 ZR 1 remote ports may be paralleled so that a single remote controls both Zones. Selector logic is active low Gray Code with pull-up provided in the CP 64S. Control may be a simple switch closure to ground or 5 volt TTL. Remote control for each zone is initiated by engaging the RMT switch (located on the front panel) for that Zone.

SCP 2S Equalizer-Only Security Cover Accessory

Just the equalizer section may be protected from the fingers of young audiophiles. Available separately.

Another alternative is the RPM series of Drag Net products. Their paging functions include a Priority Auto Mixer/Ducker, Ambient Noise Compensator, Automatic Gain Control, Equalization, Feedback Suppression and additional signal processing in up to 8 in / 8 out configurations (depending on the RPM unit).
