Headset Microphone Model HY1/HY2
GENERAL DESCRIPTION
The TOA HY 1 and HY 2 are headset type microphones
designed for professional level applications in recording, live
sound reinforcement, and broadcast environments. Unlike
the typical handheld or stand mounted mic, the "hands-free"
configuration allows the user to concentrate on the perfor-
mance rather than the microphone. The HY's feature a uni-
que design which provides superb performance and number
of functions never before available. They are ergonomically
designed to ensure comfort and stability for sustained
periods of time, without fatigue. The HY 1 and HY 2 are iden-
tical in design and function with the exception of the head-
band. The HY 1 headband is designed for extended wear, and
the HY 2 headband is designed to be hidden in the user's
hair.
The fixed-charge condenser mic element employs a back-
electret type design with a gold-vaporized, extremely thin
membrane (4µm) to provide superior performance and high
stability. Frequency response is tailored to roll off the low
end, producing a well balanced low frequency characteristic
and eliminating problems associated with "proximity effect."
(Proximity effect causes the mic to accentuate the low fre-
quencies, and in extreme cases may cause the vocal to
sound boomy and muffled.) A cardioid pickup pattern ensures
that surrounding noise is rejected, allowing the vocal to be
clear, clean and distinctive.
The HY headsets are equipped with an interchangeable mic
capsule which is voiced for male vocal response (HMV),
however, optional capsules are available. The HFV is voiced
for female or tenor male vocals, and the HCM for limited
bandwidth intercommunications. All mic capsules feature a
red LED to give a visual indication of "mic live" status. A
cough button is also provided on the headset to allow the
user to turn the mic element off when necessary (the LED
goes out).
The HY headsets are equipped with a sturdy beltpack which
provides operating power, mixing, and stereo monitoring
functions. The monitoring system is designed to allow the
user to independently control monitor (foldback) sends and
personal vocal level through the integral stereo headphone
system, directly from the beltpack. An optional 15 foot exten-
sion cable (C15-HY) allows the beltpack to be isolated from
the headset. The HY systems may be operated from two 1.5
volt "AA" batteries, or from an external phantom power
supply.
