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 continuously adjustable volume 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 available as an added accessory.
AL1 GENERAL DESCRIPTION
The AL1 is an all-in-one miniaturized UHF wireless presentation transmitter with a built-in microphone.
Despite its ultra small size, the AL1 has power and mute switches, an input level control and a twofunction LED that indicates when the transmitter is on and transmitting signal and when the battery needs to be changed.
The AL1 transmitter has a built-in unidirectional electret condenser mic, which features a metal windscreen and provides clear, crisp reproduction of speech. For enhanced versatility, it also allows a user to plug a lavalier mic into the standard 2.5mm mini-jack. The AL1 even provides
2.7 volts of phantom power so condenser mics can be used if desired.
An alligator clip allows the AL1 to be mounted on a lapel, pocket or belt. Or it can be worn around a presenter’s neck using the convenient lanyard. Featuring the ability to operate on one AAA battery, the AL1 will provide exceptional wireless reception for up to 14 hours on that single battery. And since it’s a UHF transmitter, the system is operating on a clearer frequency band with less interference.
QL5 GENERAL DESCRIPTION
As a professional, miniature clip-on condenser microphone, the QL5 lavalier is an ideal choice for close body miking in presentation and video applications. Manufactured with extreme care and the highest quality components, the QL5 delivers exceptionally clear and articulate vocal reproduction thanks to its electret condenser element. Easily attached to a necktie or jacket lapel, a maximum amount of gainbefore-feedback can be achieved as a result of the QL5’s tight cardioid pickup pattern which also reduces background noise. Additionally, its high SPL capability and lightweight, low profile design make this lavalier mic an excellent choice for a wide variety of vocal miking applications.
