Detail 01
Power amplifier, not a mixer
No preamps, EQ, or channel strips. It takes line-level signal from a mixer and drives passive speakers.

CrownCDi1000 Power Amp
1/3
Independent shopping perspective
The Korena take
Two-channel installed-sound power amp for fixed PA systems. For integrators and venues wiring permanent speaker systems, not for players plugging in an instrument.
Strong match
Who this is for
- Powering ceiling or wall speakers in a permanent venue install
- Rack-mounted front-of-house systems in clubs and houses of worship
- Replacing a failed amp in an existing Crown-based rack
Consider the trade-offs
When to look elsewhere
- Guitarists or bassists — this is not an instrument amplifier
- Anyone with powered speakers that already have amps built in
- Mobile DJs wanting an all-in-one powered mixer
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
CDi series, installed sound
Built for racks that run unattended for years, with protection circuits and consistent thermal behavior.
Detail 03
Two channels
Drives a stereo pair, or bridges to one higher-power channel for a subwoofer, depending on configuration.
Detail 04
Rack format
Needs a rack with ventilation clearance. Fan noise makes it unsuitable for a quiet room.
Detail 05
$1,803
Priced at the installation tier, above portable amps. The cost is reliability and serviceability over years, not more volume.
Final check
Know before you order
- 01Match the amp's power rating to your speakers' impedance and wattage before wiring
- 02Speaker cable, rack, and input cabling are not included
- 03Confirm whether your speakers need 70V/100V distributed lines or low-impedance
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I use this with my guitar?
No. This has no instrument preamp or gain stage. It takes line-level signal from a mixer and powers passive PA speakers.
02Do I need a mixer with this?
Yes. A power amp only amplifies an incoming line-level signal. You need a mixer or processor ahead of it to set levels and shape sound.
03Will this work with powered speakers?
No, and it would damage them. Powered speakers already contain their own amplifier and expect line-level input, not speaker-level output.
04How much rack space does it need?
Confirm the rack unit height against your rack before ordering, and leave ventilation clearance above and below since installed amps generate heat under sustained load.
