Designed for applications requiring a large number of stereo inputs, the XR-24 is a member of the XR Series of professional rack mount mixers. XR-24 meets the various needs of broadcasters, production and post-production houses, project studios, houses of worship, portable and permanent sound reinforcement and, of course, musicians. All XR Series mixers are designed to be highly flexible in fulfilling varying requirements.

Crest Audio's console engineering group has drawn from decades of large and medium-format console design to create a compact, feature-filled rack mount mixer that meets or exceeds what all other rack mount mixers offer in terms of quality, reliability and flexibility, regardless of price. AES-sug- gested grounding procedures are followed, resulting in excellent rejection of RF interference and ground-related noise. X- Rack mixers exhibit less than +/- 30 degrees of input - to - output phase shift, which is significantly better than most other consoles. XLR connectors are used on all primary inputs and outputs, while 1/4" TRS connectors are used for inserts, making it easy to interface with most professional audio gear.

As with all of Crest Audio's mixing consoles, top quality components and advanced manufacturing techniques are used throughout. This gives us the confidence to include a five-year warranty, guaranteeing years of trouble-free service.
