Designed
and developed by Robert Bradshaw, well known for
his world class Guitar Switching Systems. The 4x4
is the first in a series of high-quality audio
switching modules for Custom Audio Electronics that
can be used whenever ultra low noise, sonically
transparent signal routing is required. Consisting
of four discrete audio loops and four relay contact
closures, the 4x4 is activated by MIDI controller
data and may be configured for a wide variety of
uses.
Features:
•
Sonically transparent, passive audio switching
elements.
• Ultra low noise, wide bandwidth and dynamic
range.
• Silent, click-free switching... even in high
gain applications.
• Separate in, out, send and return jacks for
each of the four audio loops.
• Different audio switching elements can be
installed for critical applications (consult
factory).
• Super low noise buffer circuit for high to
low impedance matching (bypassable).
• Four relay contact closures (C1-C4) for
devices utilizing switch to ground functions.
• Stereo jacks for C1-C4 allow normally open
or normally closed relay operation.
• MIDI controlled - simple to operate. Can be
activated by a wide variety of MIDI controllers
including the CAE RS-10 and RS-10 MKII.
• Powered by a 9 volt AC or DC remote power
supply for lowest noise.
• Front panel LED display indicates status of
each loop and control function.
Uses/Benefits:
•
Loops 1 through 4 can be used at instrument level
before amps for switching pedal effects, or at line
level for high quality signal processing between
preamps and power amps.
• Transparent; when used in line between
instruments and amps, the 4x4 loops cause no
audible signal degradation or added noise.
• Loops can be configured as in-line bypass,
audio muting and A/B select circuits with silent
switching.
• Relay control C1-C4 functions are completely
isolated, preventing ground loops and can be used
to channel switch amps or wherever a latching
footswitch function is used.
• High quality, low noise buffer circuit
prevents unnecessary loading of high impedance
instruments, thus allowing multiple amp
combinations and long series chains of effects with
unsurpassed clarity. Buffer can be bypassed for a
completely passive switching system or factory
adjusted for optimum use.
• Modular. More than one 4x4 may be used in a
system with individual access to each loop or
control function via MIDI controller data. Systems
using more than one 4x4 can expand as your needs
grow.
• Can be used to expand and improve
performance of existing systems such as the
Rocktron/Bradshaw RSB18R (consult factory for
details).
