Orator-G headsets feature a noise-canceling microphone to eliminate background
noise and a click-stop adjustable headband for on-the-job comfort. The OG-II
single-
wire binaural
adds a second pivoting speaker to help keep the wearer focused.
The MPA-II Multi-Purpose
Amplifier
works on most
phone systems with a modu-
lar handset connector. The
easiest amplifier to set up
and use, it features a sliding
volume control, headset/
handset switch, mute switch
and a built-in headset stand.
An optional on-line indicator
signals when the headset is
in use.
Our 0686 In-line Amplifiers
provide a cost-effective option
for standard carbon applica-
tions. Incredibly compact, they
feature a rotary wheel for a
broad range of volume adjust-
ments. Also available with a
mute button,
0686M.
The 0452 Two-Prong
Amplifier
is designed for
telephones equipped with a
two-prong headset port. Its
3-position volume control
locks your volume preference
in place.
Also available: The 0911 Two-Prong 6-Wire Amplifier, for push-to-talk dispatch/911 environments;
and the HT One Headset Telephone (HT-1), the first professional-quality telephone with an inte-
grated headset—ideal for PBX and CTI applications.
There’s a GN Netcom amplifier for every need and every application. Like our headsets,
all GN Netcom amplifiers feature a two-year warranty.
