OPERATION

INTRODUCTION

Congratulations on choosing this Clear-Com product. Clear-Com was
established in 1968 and remains the market leader in providing intercoms for
entertainment, educational, broadcast and industrial applications. The
ruggedness and high build-quality of Clear-Com products defines the industry
standard. In fact, many of our original beltpacks and main stations are still in
daily use around the world.

The HB-702 two-channel and HB-704 four-channel headset stations are
powerful, yet user-friendly units that can serve as versatile intercom stations.
Please read this manual completely to better understand the functions of these
products. If you encounter a situation or have a question that this manual does
not address, contact your dealer or call Clear-Com directly at the factory. Our
applications support and service people are standing by to assist you. (Refer to
Chapter 5: “Warranty” for contact information.) Thank you for selecting
Clear-Com for your communications needs.

DESCRIPTION

The Clear-Com HB-702 and HB-704 headset stations are ideal for use in
theatres, live performances, industrial environments, and small television
facilities. They feature speech intelligibility in all noise levels and can be
customized through their programmable options.

Selectable, multi-channel talking and/or listening allows the operator to
communicate on one of two (HB-702) or four (HB-704) intercom channels.
The dual-action talk button operates in electronic momentary or latching
mode. The HB-702 and HB-704 offer visual call signaling to attract the
attention of operators. The remote mic kill (RMK) feature on main stations
will turn off any open microphones on these headset stations.

The HB-702 and HB-704 stations accept dynamic headsets, such as the
Clear-Com or the HS-6 telephone headset series. A sidetone control allows
the operator to vary the level of his voice as heard in the headset.

The HB-702 and HB-704 receive power from the Clear-Com intercom line.
They mount in a standard two-gang electrical outlet box.

The extra-thick front panel and compact, surface-mount circuitry results in a
smaller-sized and lighter-weight package that maintains Clear-Com
ruggedness. The intercom channels connect to a plug-on screw-terminal strip.

The optional EB7-TW daughter board module can be installed to provide an
interface to two intercom channels on a single microphone cable. Also, the
EB7-4W four-wire daughter board module is available to allow long-distance
connections using separate pairs of wire for send audio and receive audio. The

The HB-702 and HB-704 are compatible with all Clear-Com party-line
intercoms.

OPERATION

Normal operation of the HB-702 or HB-704 headset station requires only the
front-panel controls. The controls located elsewhere on the unit are intended
to be set-and-forget in nature. For intercom operation, set the volume control
to the desired level and press the talk button when talking. Set the sidetone
control for the desired amount of sidetone in the earphone.

FRONT PANEL

The controls, indicators, and connectors found on the HB-704 front panel are
shown in Figure 1-1 and are described by the following text. The HB-702
front panel is identical except the channel switch has two positions.

Figure 1-1 HB-704 Front Panel

1. Talk button and light: The talk button activates the microphone feed to
the selected intercom channel. The talk button has a dual action
(momentary or latching) depending upon how the button is pressed. If
desired, the latching function can be defeated using an internal switch.
The following describes the various functions of this button.

• MOMENTARY: Press and hold the talk button while speaking.

Release it when finished.

1-2

HB-702/HB-704 TWO- AND FOUR-CHANNEL HEADSET

• LATCHING: Press and release the button quickly to latch the talk

function. Press and release the button again to turn off the talk
function.

• TALK INDICATION: The talk button lights amber when the talk

function is active. When the talk function is not active, but the station
is receiving electrical power, the button lights blue.

2. Call button and light: Pressing the call button will send a call signal on
the selected channel. All the call lights on that channel will then flash.
Call signals can also be sent while talking if required. The call light will
light red while the call button is pressed, or whenever a call signal is
present on the selected channel.

3. Volume control: Turn this control to set the volume required on the
headset.

4. Sidetone control: Sidetone is the level of the operator’s voice that is
heard while talking on the intercom. Setting a comfortable level of
sidetone will ensure that the intercom line sounds alive and also helps
modulate the operator’s voice relative to other voices on the line. Use the
following procedure to correctly set the sidetone level control.

1. Set the volume control to a comfortable level by having someone talk

to the operator from another station.

2. Press the talk button and speak into the microphone while turning the

sidetone control slowly back and forth until you hear your voice at a

comfortable level in the headset.

Note: Do not force the trimpot past its stop points. This will damage it.

5. Channel switch: This switch selects the intercom channel (A, B, C, or D)
on which the headset station is active.

6. Headset connector: The headset connector is located on the front panel.
All Clear-Com headsets are recommended for use with the HB-702 or
HB-704. The Clear-Com PT-7 push-to-talk microphone or the HS-6
telephone handset will also plug into the headset connector. The
following is a description of the characteristics of a suitable headset:

Mic Type --- Dynamic; see technical specifications for details

Headphone --- Dynamic; see technical specifications for details. The wir­ing of the headset is to be as follows:

Pin 1 --- microphone ground (shield)

Pin 2 --- microphone hot

Pin 3 --- headphone ground

Pin 4 --- headphone hot

The microphone and headphone wiring in the headset cord must be indi­vidually shielded. Do not connect pins #1 and #3 together. Headset
extension cords or headset “Y” cables are not recommended because they
may increase crosstalk between channels.

INTERNAL ADJUSTMENTS AND CONNEC­TIONS

The controls and connectors found inside the HB-702 and HB-704 are shown
in the following figure and described by the following text. The jumpers can
be accessed without completely removing the panel from its wall box by
removing the top two screws and loosening the bottom two screws a few
turns. The panel can then be leaned out from the wall. The jumpers will be
accessible as shown in the lower view of Figure 1-2.

mode, the talk button must be held in continuously while the operator
is talking.

• Switch 2—Long Line. If a long cable run is unavoidable and

approaches 1,000 ft. (305 m) or more, set the long line option jumper
to the on position. The ability to set a sidetone null depends upon
properly setting this switch.

8. Intercom Line Connection: The HB-702 and HB-704 contain a
seven-terminal, plug-on connector for intercom line connection. This
connector is intended to be unplugged from the circuit board when
connecting the intercom line(s), then plugged back on when the wiring is
completed. If less than the maximum number of intercom lines are to be
connected to the intercom connector, link unused intercom inputs to a
connected input with jumper wires. The connections for each pin are
visible on the circuit board when the connector is unplugged. The pinout
of this connector is as follows:

Pin 1--- (NC)

Pin 2 --- Channel A audio

Pin 3 --- Channel B audio

Pin 4 --- Power

Pin 5 --- Ground (shield)

Pin 6 --- Channel C audio (HB-704 only)

Pin 7 --- Channel D audio (HB-704 only)
