Atlas Sound CP700 Dual-Channel, 700-Watt Commercial Power Amplifier

Product Overview

The Atlas Sound CP700 is a dual-channel 700-watt commercial power amplifier engineered for contractor-grade 70V distributed audio installations and high-SPL sound reinforcement. Its professional Class A/B design pairs a toroidal power supply with toroidal output transformers, delivering true transformer output isolation that was traditionally cost-prohibitive when sourced as external hardware. Each channel produces 350 watts at 70.7V, with 400 watts per channel at 4 ohms and 700 watts in bridged mono, covering everything from constant-voltage paging zones to direct-coupled loudspeaker systems. For integrators specifying amplification for commercial paging system installation, the CP700 combines high power with isolation, protection, and serviceable design details.

Product Description

The CP700 was specifically designed for demanding contractor applications where reliability over years of continuous duty matters more than spec-sheet novelty. The esoteric-grade toroidal power supply and output transformers were chosen for outstanding reliability and extended frequency response, with the transformer-coupled output holding -3 dB from 30 Hz to 16 kHz. Transformer isolation gives system designers the safety margin required by worldwide safety agencies and protects downstream 25V, 70.7V, and 100V constant-voltage speaker lines — a meaningful advantage in distributed audio system integration across large facilities.

Two fully independent channels maximize channel separation and keep distortion low, so paging and background music zones never interact. Output connections for 25V, 70.7V, 100V, and direct-coupled 2-, 4-, and 8-ohm loads terminate on barrier strips with safety covers, while balanced inputs accept both barrier strip and XLR terminations. A loop-through male XLR per channel input simplifies daisy-chaining multiple amplifiers in larger racks. Rear-mounted stepped attenuators keep level settings secure from casual adjustment, power-up muting prevents turn-on thumps through the loudspeaker system, and dual-speed high-efficiency fan cooling keeps the 3RU chassis stable under load. The CP700 is UL listed to UL60065 for commercial installation compliance. Match it with 70V loudspeakers and accessories from our AtlasIED collection to complete the system.

Key Features

• Toroidal Output Transformers — Full electrical isolation on every output meets worldwide safety agency requirements and protects long constant-voltage speaker runs.
• Flexible Output Options — 25V, 70.7V, 100V, and direct-coupled 2-, 4-, and 8-ohm outputs on covered barrier strips serve distributed and low-impedance systems alike.
• High Power Density — 350W per channel at 70.7V, 400W per channel at 4 ohms, and 700W bridged mono at 140V/200V cover large zones from one chassis.
• Independent Dual Channels — Separate channel architecture maximizes separation and keeps distortion low across paging and music zones.
• Balanced XLR and Barrier Inputs — Both connector types plus per-channel XLR loop-through simplify multi-amplifier rack integration.
• Power-Up Muting — Turn-on transients are muted so amplifier power sequencing never sends thumps through the loudspeaker system.
• Rear-Mounted Stepped Attenuators — Level controls on the rear panel stay secure from tampering in shared equipment rooms.
• Dual-Speed Fan Cooling — High-efficiency variable cooling maintains safe operating temperature during continuous commercial duty.
• UL Listed (UL60065) — Agency listing supports specification in commercial and government projects.

Typical Applications

• Houses of worship
• Auditoriums
• Government spaces and public buildings

• Training rooms

Technical Specifications

Frequently Asked Questions

What speaker systems can the CP700 drive?

It supports 25V, 70.7V, and 100V constant-voltage distributed speaker lines plus direct-coupled 2-, 4-, and 8-ohm loudspeakers, and can bridge to 700W mono for a single large zone.

Why does transformer output isolation matter?

Transformer isolation electrically separates the amplifier from long speaker runs, meeting worldwide safety agency requirements and protecting the system from line faults — normally an added cost when done with external transformers.

Can I chain multiple CP700 amplifiers from one source?

Yes. Each channel input includes a male XLR loop-through, so a single source can feed several amplifiers in a rack without external distribution hardware.

How is it protected against turn-on noise?

Power-up muting suppresses turn-on transients, so power sequencing in larger AV racks will not send thumps through connected loudspeakers.

How much rack space does it occupy?

The CP700 is a 3RU chassis (5-3/16" tall) for standard 19" equipment racks, with dual-speed fan cooling for densely packed installations.

What warranty applies and who supports it?

AtlasIED warrants the CP700 for 36 months from date of purchase, and Creation Networks assists with both system design questions and warranty service.
