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.
