INPUT PANEL
1. Ground lift (inputs) Lifts
the ground pin-1 on both
XLR input connectors.
2. Input-1 & 2 For low
impedance 600 ohms,
balanced line-level signals.
3. Bookend design 14
gauge steel outer shell
creates protective zone
around connectors and
switches.
OUTPUT PANEL
4. Output-1 & 2 600 ohm
line-level transformer-
isolated.
5. Polarity reverse 180°
Polarity reverse phase
reverse switch for
outputs-1 & 2.
6. Full-bottom no-slip pad
This provides electrical
isolation and plenty of
"stay-put" friction to keep
the Twin-Iso in one place.
CONSTRUCTION
7. Ultra rigid steel I-beam
enclosure eliminates
stress that could torque
the PC board and cause
solder joint failure.
8. Radial Eclipse
transformers offer
outstanding audio
performance.
9. Military-grade double-
sided PCB with plated
through-holes is bolted to
welded steel standoffs.
10. Sturdy high-cycle PCB
mounted switches are
rated for long life.
