Part 2 – The JDI Feature Set
(1)
15dB PAD
switch - a -15dB pad can be introduced to
reduce the input voltage and ensure a clean, distortion-
free signal.
(2)
MERGE
switch - left-right merge function turns the
input and thru-put connectors into a pair of left-right inputs
with a mono output at the XLR.
(3)
INPUT
- 1/4" jack, 130kOhm instrument input.
(4)
THRU
- 1/4" jack, thru-put to send instrument signal
through to the instrument amplifier.
(5)
Protective bookend cover
overhangs the chassis
providing protection for switches and connectors.
(6)
Welded I-beam construction
for maximum strength
and durability and a baked enamel finish offer years of
trouble free performance.
(7)
Full bottom no-slip pad -
reduces slipping in use and
provides mechanical and electrical isolation.
(8)
Double sided PC board -
military grade circuit board
features a full ground plane for maximum protection
against stray magnetic fields and RF noise.
(9)
XLR
output
connector - wired to the AES standard
with pin-1 ground and pin-2 hot, provides a balanced
150-Ohm mic level signal.
(10)
POLARITY
switch - 180º polarity reverse toggles the
XLR pin-2 and pin-3 to interface with older equipment.
Also used when combining two sources such as a mic
and a DI.
(11)
GROUND
switch - lifts the XLR pin-1 ground at the
output to eliminate hum and noise caused by ground
loops.
(12)
SPEAKER
switch - a pad circuit that allows you to tap
the signal from a speaker cabinet. Features a band-pass
filter to emulate a 12" driver.
Note
: Only use in parallel
with a speaker cabinet or load box.
