Supra Headset— a monaural headset with an adjustable headband. It
offers a soft ear, comfortable cushion that reduces surrounding noise,
making it easier to understand the caller.
Supra NC Headset— a binaural headset with adjustable headband and
ear cushion for working in noisy environments. Its noise-canceling
soft
microphone and voice expansion technology reduces up to 75% of the
surrounding noise.
Each headset is light, comfortable and uses a transparent voice tube to
eliminate the cumbersome large microphone. Each model comes with a 10-foot
(305-cm) coiled cord and a Quick Disconnect latch.
These headsets work with any telephone connected to the communications
system when combined with one of the amplifiers described in the following
section.
See Figures 2-18 and 2-19.
The following amplifiers work with the supported headsets:
Modular Amplifier— connects the StarSet, Mirage, Supra, and Supra NC
headsets to virtually any telephone equipped with a modular handset. It
is installed without special tools. You can adjust the incoming volume,
switch between the headset and handset as needed, and temporarily
mute the line.
Plug Prong Amplifier (for non-MLX telephones)—connects the StarSet,
Mirage, Supra, and Supra NC headsets to operator consoles, telephones
equipped with a headset adapter, and many automatic call distributors.
It provides switch-hook control for answering calls by pressing a button,
You can also adjust the incoming volume.
Both amplifiers provide safety and comfort features that protect you from
unexpected loud signals and provide clear sound. The amplifier stays with the
telephone and works interchangeably with individual headsets.
