Designed for applications requiring a large number of stereo
inputs, the XR-24 is a member of the XR Series of profession-
al rack mount mixers. XR-24 meets the various needs of broad-
casters, production and post-production houses, project stu-
dios, houses of worship, portable and permanent sound rein-
forcement 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 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 -
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 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.
