Description

Designed for today’s demanding applications, the XR-20 is the first in a line of professional Crest Audio X-Series rack mount mixers, which address a wide range of applications. The XR-20 meets the varying needs of project studios, houses of worship, broadcasters, musicians and all facets of live sound reinforcement where it can be used as the primary mixer or as a highly flexible submixer.

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.
