HANDHELD MICROPHONE SYSTEM CR77 WITH AX1

SERIES CATEGORY

AIRLINE 77 WIRELESS

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.
