The Radial JS•2 and JS•3 are Jensen transformer-equipped mic splitters that allow a balanced
source to drive multiple destinations via standard XLR connectors. These passive devices feature
a premium nickel laminated core transformer for exceptionally low harmonic distortion without the
usual phase shift caused by lesser steel core transformers.

The JS•2 and JS•3 offer the undisputed benefi t of 100% transformer isolation with better than

-90dB common-mode noise rejection (CMR), thus eliminating troublesome hum & buzz caused
by stray voltage and ground loops. These ‘problem-solvers’ offer a simple yet highly effective
interface for microphones or direct boxes, and with the addition of the -30dB pad, consumer and
line-level devices may be employed without distortion or fear of overload due to saturation.

The Radial JS•2 and JS•3 mic splitters feature a rugged 14 gauge steel construction for maximum
durability. Up to 8 units may be rackmounted in 2RU using the Radial J-Rak. The Radial JS•2 and
JS•3 mic splitters are easy to use, fl exible and sound great!

2-Way Microphone Splitting

Isolated

INPUT PAD Reduces input by 30dB
to allow +4dB line-level devices to
be connected.

MIC INPUT Standard 600Ω main
input.

DIRECT THRU-1 600Ω Connects to
main PA with phantom-power return
path to microphone.

FULL BOTTOM PAD Improves elec­trical isolation and keeps the unit in
one place.

DIRECT THRU-2 600Ω Second
direct out can connect to recording
or monitor systems. On the JS•3 this
output is transformer-isolated.

ISOLATED OUTPUT 600Ω Con-
nects to a recording or broadcast
system without noise.

GROUND LIFT On outputs can
eliminate hum and buzz caused by
ground loops.

JENSEN audio transformers provide
100% isolation to eliminate noise
caused by ground loops, and they
sound great!

HEAVY-DUTY WELDED I-BEAM
enclosure of 14 gauge steel makes
it impossible to torque the PC board.
Eliminates cold solder joints.

RUGGED XLR connectors are glass
fi lled nylon and eliminate chassis
ground potential for 100% electrical
isolation.

MU-METAL SHIELD for protection
against radio frequency and electro­magnet interference.

MILITARY-GRADE PC board inside
with full ground plane to reduce
susceptibility to RF noise.
