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 two-
function 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 gain-
before-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.
