Peavey CPX 1 Professional Power Amplifier
Robust Class‑AB amplifier — reliable power for touring, live sound, installations and PA use.
The Peavey CPX 1 is a versatile, high‑performance power amplifier from the Crest Audio CPX series — built to be the backbone of mobile sound systems, studios, live‑sound rigs or fixed installations. With support for low‑impedance speaker loads down to 2 Ω per channel (or 4 Ω bridged) and generous power delivery across impedance ranges, CPX 1 ensures clean, dependable output even under demanding conditions. Built‑in crossover, low‑cut filter, signal limiting, and flexible connectivity make this amp suitable for full‑range speakers, subwoofers, or mixed PA systems — a great all‑purpose amp for DJs, venues, musicians and installation setups.
Key Features
-
Flexible power output: 300 W @ 2 Ω per channel, 480 W @ 4 Ω per channel, 290 W @ 8 Ω per channel; bridged mono delivers up to 960 W @ 8 Ω / 600 W @ 4 Ω.
-
Supports low-impedance loads: Minimum 2 Ω stereo — ideal for demanding speaker loads or multiple‑cabinets per channel.
-
Integrated crossover & filters: Fixed 150 Hz Linkwitz‑Riley low-pass crossover (–24 dB/octave) and 40 Hz low‑cut filter — useful for subwoofer setups and preventing rumble.
-
Built‑in protection & GCL limiting: Automatic Gain Comparator Limiting monitors input/output gain and reduces signal to protect speakers from transients or current overloads (switch‑offable via rear panel).
-
Comprehensive connectivity: Inputs via barrier‑strip, XLR / ¼″ combo TRS; outputs via binding posts and 4‑pin twist‑lock — supports stereo and bridged‑mono modes.
-
Dual‑speed DC cooling fan & dual-voltage operation: 115 V / 230 V compatibility and thermal‑safe cooling make it suitable for touring, installations or indoor rigs worldwide.
-
Rack‑mountable 2U chassis: Fits standard 19″ racks (483 mm width), making it easy to integrate into pro audio racks or live‑sound racks.
