CR77 GENERAL DESCRIPTION
The CR77 is a true diversity UHF receiver that can be
used freestanding or mounted in any standard 19-inch
rack, making it easy to integrate into any traveling or
fixed installation audio system. It includes a pair of
tuned antennas and the synthesized PLL frequency
control circuitry keeps the signal locked and true
while LEDs monitor the true diversity operation.
The CR77 features a front panel display with large
six-segment audio level and RF level LED meters
along with a large rotary volume knob that allows
easy adjustment of audio output. The unit also houses
a line/mic output level switch and squelch controls.
The rear panel features balanced XLR and unbalanced
1/4-inch outputs allowing flexible connection options.
Two CR77 receivers can even be rackmounted together
in a single-space rack adapter (RK55) available as an
added accessory.
AX1 GENERAL DESCRIPTION
The compact AX1 Handheld UHF Transmitter allows a
user to convert any dynamic microphone into a wireless
mic. It’s as simple as plugging the standard female XLR
connector of the AX1 into any standard wired dynamic
microphone, making it easier than ever to go wireless.
And because it’s so small and lightweight, the AX1 feels
like a natural part of the microphone.
Despite it’s small size, the AX1 features a power switch,
microphone input level control and a power/battery LED
that conveniently indicates when there is less than two
hours of battery life remaining. The AX1 also operates
for up to 14 hours on a single AAA battery. Plus, as
a UHF transmitter, it operates on clearer frequencies
with less interference.
