PROFESSIONAL SOUND SYSTEM  
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 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.  
FEATURES  
1. Ergonomic "hands-free" design provides secure attach-  
ment to user's head, and allows comfortable wear  
without fatigue.  
2. Smooth, extended "vocal" frequency response, and ex-  
cellent transient response.  
3. High quality, fixed-charge condenser microphone element  
with cardioid pick-up pattern. Interchangeable mic cap-  
sules allow precision response tailoring for optimum  
vocal performance.  
4. Standard version is fitted with mic capsule designed for  
male vocal response (HMV). Optional capsules are  
available for female vocal, or male tenor vocal (HFV), and  
limited bandwidth intercommunications (HCM).  
5. Integral stereo headphone monitoring system for "per-  
sonalized" foldback and cueing functions.  
6. Red LED lights to indicate "mic live" status.  
7. Cough button.  
8. Headset may be worn from either right or left side.  
9. System may be powered from two 1.5 volt "AA" bat teries.  
or an external phantom power supply.  
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).  
10. Sturdy beltpack provides operating power, mixing and  
monitoring functions.

6. Turn the beltpack power switch to "OFF," and  
1. Assemble the HY headset according to the  
assembly diagram.  
(A) Attach the head pad marked "L" to the left side of  
the headset, and the head pad marked "R" to the  
right side, by pressing firmly until they "snap" into  
rotate the monitor level volume control to "MIN"  
and the monitor balance control to its center pos-  
tion. Connect an XLR cable between the MIC  
OUTPUT of the beltpack, and a low-Z input of a  
mixer or sound system. If the integral monitoring  
system is to be used, insert a stereo or mono 1/4"  
phone plug into the LINE INPUT JACK, and slide  
the line mode selector switch to the appropriate  
setting.  
place.  
(B) Connect the interconnecting cable to the headset  
and the beltpack, ensuring that the locking ring of  
each connector is fully engaged.  
(C) If the internal monitoring system is to be used,  
connect the stereo mini plug of the PH 5 head-  
phone to the headphone jack of the headset.  
(Note: Other stereo headphones with an im-  
pedance of 16 ohms or greater may be used if  
desired.)  
7. Place the beltpack power switch in the "ON" posi-  
tion. Set the COUGH BUTTON to the "ON" posi-  
tion, and the red LED will light to indicate "mic  
live"status. Rotate the MONITOR LEVEL VOLUME  
CONTROL to obtain a desirable level in the head-  
phones, and adjust the MONITOR BALANCE CON-  
TROL to obtain the proper "mix" between the direct  
vocal and the line input monitor signal.  
2. Insert the "L" and "R" units of the headphone into  
the respective left and right ears as illustrated.  
8. For right-side operation, reverse the positions of the  
"L"and "R" head pads. The MIC ARM should be  
reversed by carefully pulling the CANTILEVER out  
away from the headset (just enough for clearance)  
and swinging it to the other side; then gently lower  
the arm to the surface of the headset. Orient the  
red LED of the mic capsule toward the face, by  
first loosening the MIC ADJUSTMENT KNOB, turn-  
ing the shaft, and then retightening the knob.  
3. Set the cough button to the "mic off" position.

4. Position the headset so the "L" and "R" head pads  
rest immediately above the respective "L" and "R"  
ears, and adjust the headband for a comfortable fit.  
5. Loosen the mic adjustment knob, and position the  
mic capsule approximately 10-25mm (1/2-1 inches)  
from the corner of the mouth. Ensure that the can-  
tilever is positioned fully downward, and carefully  
tighten the mic adjustment knob to hold the mic  
arm in the desired location. You should experiment  
with the positioning of the mic capsule, in relation  
to the mouth, to determine the location that pro-  
vides the best reproduction of your individual vocal  
tonality and performing style.

Stereo Headphone Monitoring System  
The stereo headphone monitoring system was designed to monitor the vocal, direct from the  
mic capsule, and mix it with an external line level input signal, such as a monitor (foldback)  
signal from a mixing console. The combined signals are sent to the stereo headset after being  
amplified by the beltpack's stereo amplifier. This allows the user to adjust his own mixing  
balance and master sound level independently of other performers. Disconnecting the head-  
phone makes it possible to use the headset only as a microphone.  
The monitoring system is powered by two 1.5 volt "AA" dry cell batteries, which are housed in  
the beltpack. To operate the unit, turn the battery power switch to the "ON" position. Please  
note that even though the HY headset is designed to operate from an external "Phantom"  
power supply, the monitoring system, because of its relatively high power requirements, still  
requires power from the batteries in the beltpack.

Battery Power Switch and Phantom power supplies:  
This switch turns the beltpack battery power supply  
on or off. Setting the switch to ON supplies battery  
power to the mic capsule as well as to the head-  
phone monitoring system. If phantom power is sup-  
plied from an external source to the beltpack, the  
mic capsule is automatically switched to the exter-  
nal source for its operation, regardless of the posi-  
tion of the BATTERY POWER SWITCH.  
Line Mode Selector Switch:  
The switch setting should be determined by the  
type of 1/4" plug (stereo or mono) which is inserted  
into the LINE INPUT jack. Place the switch in the  
STEREO position when a stereo plug is inserted,  
and to MONO when a mono plug is inserted. Set-  
ting the switch to the MONO position when a  
stereo signal is inserted will cause the "R" signal to  
be disconnected from the circuitry, and only the  
"L" signal will be heard through the headphones.  
Please see the block diagram for a full understan-  
ding of the signal flow path.  
NOTE:  
The headphone monitoring system always requires  
battery power from the beltpack, due to the  
relatively high power requirements common to this  
type of system.  
Monitor Balance Control:  
This control adjusts the balance or "mix" heard  
through the stereo headphone system, between the  
direct vocal from the headset mic, and the line in-  
put signal. The volume of the direct vocal in-  
creases in relation to the level of the line input  
signal as the control is rotated toward "MIC," and  
decreases as the control is rotated toward "LINE."  
Line Input Jack:  
This jack accepts any line level input signal, and is  
rated +4dB 10K-ohms. The jack would typically be  
connected to either a stereo or mono send from a  
mixing console. It also serves very well as an input  
for a tape deck or other pre-recorded music  
source, except a magnetic turntable. Set the LINE  
MODE SELECTOR SWITCH to STEREO or MONO  
according to the type of 1/4" phone plug which is  
inserted into this jack.  
Monitor Level Volume Control:  
This control adjusts the volume level heard through  
the stereo headphone system. It does not in any  
way effect the output of the mic signal through the  
MIC OUTPUT connector.  
Mic Output Connector:  
The vocal signal from the headset microphone is  
routed to this XLR connector. The signal available  
at this output is not affected by the settings of  
either the MONITOR BALANCE CONTROL or the  
MONITOR LEVEL VOLUME CONTROL. The output  
impedance is 250 ohms balanced, and would  
typically be connected to a low impedance XLR  
connector of a mixing console or powered sound  
system.
