Look
inside a JS•2
or JS•3
and you will find the build quality and components to be of
the highest professional standards. Radial's proven construction
methods and materials ensure highest performance and years of
trouble-free service. The JS•2
and JS•3
feature Jensen transformers – the best
audio transformers in the industry – to achieve the highest
possible signal integrity and phase coherence while eliminating
hum and buzz caused by ground loops.

1. |
Isolated
XLR connectors to eliminate chassis ground potential. |
| |
2. |
Jensen
audio transformer on input provide 100% isolation to
eliminate hum and noise causing ground loops. |
| |
3. |
Military
spec PC board with full surface ground plane to reduce
susceptibility to RF noise. |
| |
4. |
High
grade switches - long life, high cycle for reliable
performance. |
| |
5. |
14-gauge
steel welded I-beam construction makes it virtually
impossible to torque the PC board. |

7. |
INPUT
Microphone 600 Ohm - balanced input,
female XLR connector, AES standard with Pin-1 ground and Pin-2
hot. |
| |
8. |
THRU
Direct 600 Ohm - direct output male
XLR connector, AES standard with Pin-1 ground and Pin-2 hot. |
| |
9. |
Book-end
design creates a protective zone around the switches
& connectors – indestructible 14-gauge steel construction.
|
| |
10. |
Full
no-slip rubber bottom pad provides mechanical isolation,
electrical insulation and prevents unit from sliding around. |

Construction
The JS•2
and JS•3
are designed to withstand the rigors of high- use professional environments!
Radial's innovative 'book cover' design provides a protective zone
around the switches and connectors that keeps these components safe.
Stress
on circuitboards causes broken and intermittent solder joints, a
common cause of failure in commercial rental and other high-use
environments. Radial's 14-gauge welded I-beam inner chassis and
14-gauge outer shell greatly reduce the possibility of torque stresses
being applied to the PC board.
A full-bottom
no-slip rubber pad works double duty by (a) providing protection
from electrical shock and (b)
assuring that these splitters won’t slip and slide around. |
