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, hous-
es 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 cre-
ate 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 excel-
lent rejection of RF interference and ground-related noise. X-
Rack mixers exhibit less than +/- 30 degrees of input - to out-
put 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, mak-
ing it easy to interface with most professional audio gear.
As with all of Crest audio's mixing consoles, top quality com-
ponents and advanced manufacturing techniques are used
throughout. This gives us the confidence to include a five-year
warranty, guaranteeing years of trouble-free service.
