R-100 VHF System
The COBALT R100 VHF systems operate in the
frequency band between 174.100 and 185.350
MHz (channels 7-8 in the TV band). With the
R100 Series, having EV wireless freedom has nev-
er been more affordable, cost-effective or practi-
cal. The R100’s rock-solid RF performance is the
result of superior design and state-of-the-art man-
ufacturing. The R100 receiver can also be rack-
mounted with the optional RMR accessory kit.
RTM-1000 Remote Test System
Reduce the hassle and improve the results of your
pre-concert soundchecks with the RTM-1000
Remote Test Wireless System. This system provides
a wireless link between your calibrated measure-
ment microphone and audio analyzer. That
means you can quickly test multiple locations
from the front row to the nosebleed seats in
the time it would take to haul long mic cables to just
one spot.
• Wireless link between test microphone and audio
analyzer allows faster, easier measurement of
large performance spaces
• Works with most measurement microphones
• Non-companded transmission does not affect au-
dio quality
The key feature of the RTM-1000 is the compander
on/off switches on both the receiver and bodypack
transmitter. Wireless mic systems normally use com-
panding (compressing/expanding) to stuff more
dynamic range through narrow wireless channels.
But companding can also add coloration or distor-
tion to the signal. The RTM-1000 lets you defeat
the compander circuit, leaving the signal from mic
to analyzer unchanged.
