SW4 Quad Input Switcher™

The Radial SW4 is a unique multi-channel switcher for balanced audio signals that enables four input pairs to be switched individually or be linked together to

create stereo, tri-channel or quadraphonic switching should the need arise.

Radial’s President Peter Janis explains: “Over the past several years, we have increased our focus on providing various types of switchers for microphones,

preamps, guitars, amplifiers and backing tracks. Today, the majority of artists employ wireless microphones in their live shows along with in-ear monitors. More

recently, guitarists have been replacing their stage amplifiers with digitally generated devices such as Fractal’s AxeFX. Considering most electronic devices employ

internal computers to do the work, backup systems are now becoming essential for professional touring. Computers are certainly more stable than they were in days

gone by but on stages where high voltage lighting is abundant, power spikes can pose problems. Another concern is brownouts due to fluctuating power generators

that can cause havoc with digital systems. The Radial SW4 is an advanced switcher that can be configured to back up wireless mic systems, wireless guitars, stereo

backing tracks or even be used to switch or combine mixing consoles in a festival environment.”

The design begins with four dual-input channels equipped with two balanced XLR-F inputs and an XLR output on the rear panel. Each output is Eclipse

transformer isolated, to prevent hum and buzz caused by ground loops, and is capable of handling up to +20dB at 20Hz without distortion for the most demanding

pro-audio applications. This is supplemented with top-mounted ground lift switches on each channel. Looking at the front panel, each of the four channels is

equipped with a channel-on switch, A/B select with LED indicators, signal presence LEDs and individual trim controls to match the signals. The SW4 is also

equipped with a stereo bus that lets the user combine the active outputs to a single mix point and exit the box via two dedicated balanced XLRs. The same bus

drives two unbalanced guitar outputs should the SW4 be used with wireless guitar systems. A top-mounted level control enables the tech to adjust the guitar amp

output to suit.

Finally, each of the four channels may be linked so that they all switch together. You could, for instance, have channels 1 and 2 linked for stereo use and then

use 3 and 4 independently. When linked, channels 1 and 3 show up on the left stereo bus while channels 2 and 4 show up on the right. A master mono sum switch

on the top cover brings all the active channels on the bus to both outputs. A dedicated mono-summed tuner out on the front panel can be used for monitoring or for

tuning guitars. Switching can be performed via the front panel or with the JR-2 remote. This dual function switch is available in a choice of footswitch or desk-top

models to control A/B select and master mute.

Construction follows Radial’s legendary road-worthy construction with 14 gauge steel throughout, baked enamel finish, steel encased switches and steel shafted

potentiometers. As with all Radial products, the SW4 is made in Canada and covered by a 3-year transferable warranty.

The Radial JX62 is a six input guitar switcher with two amplifier outputs for live touring.

According to Radial’s Central Regional Territory Manager, David ‘Shuu’ Guidish: “Before joining Radial, I

spent over 17 years on the road as a guitar tech. During this time, it became abundantly clear that a guitar

switching system must be easy to use, quiet, dependable and bullet proof to handle the rigors of professional

touring. When designing the JX62, the Radial R&D team discussed the feature set with me, along with a

number of other touring pros, before putting the pieces together. The combination of a guitar switcher with

built-in DI boxes for acoustics and bass, along with an amp switcher and tuner out, truly makes the JX62 a

unique and essential piece of gear.”

The Radial JX62 begins with six guitar input channels, each of which is outfitted with ¼” input and a thru connection to feed its own amp or dedicated direct box. A

simple ON switch activates the channel and a recessed ‘set & forget’ TRIM control enables the guitar technician to set all of the levels uniformly should the output from

the guitars or wireless systems need adjustment. All channels may be used at once. The trim control on inputs 1 & 2 plays double-duty whereby it can be turned into a

DRAG control – to instead adjust the load when using a wired connection to a magnetic pickup. This follows the same award winning class-A circuit topology as used

on the Radial JD7 which is used by guitarists such as Carlos Santana, Neil Schon, Steve Vai and John Petrucci. Made from 14 gauge steel with a baked enamel finish,

the Radial JX62 is able to withstand the rigors of professional touring. As with all Radial products, the JX62 is made in Canada and covered by a 3-year transferable

warranty.
