The GN 8000 Series Multi-
Purpose Amplifier

works on

most phone systems with a
modular handset connector. 
It features a built-in headset
stand with an on-line indica-
tor option that signals when
the headset is in use.

Our In-line Amplifiers 

provide a cost-effective
option for standard carbon
applications. Incredibly 
compact, and available with
or without a mute button,
they feature a rotary wheel
for a broad range of volume
adjustments.

The 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 GN 7100 Headset Telephone, a professional-quality telephone 
with an integrated headset—ideal for PBX and CTI applications.
