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, 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 KB-701 speaker station is a powerful, yet user-friendly unit that can serve
as a versatile intercom station. We recommend that you read through this
manual completely to better understand the functions of the KB-701. 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 KB-701 speaker station is designed for use in theatres, live
performances, industrial environments, and small television facilities. It
features speech intelligibility, even at high-noise levels, and can be
customized through its programmable options.

Local or remotely controlled talking or listening is selectable and allows
either hands-on or hands-free operation. The talk button operates in
momentary mode. The integral microphone and speaker offer half-duplex
communication. The KB-701 offers both visual and audible call signaling to
attract the attention of operators.

A balanced program input allows the monitoring of external audio through the
speaker. This program input can also be used as a paging function.

The integral speaker’s volume level can be adjusted using a front-panel knob.
An internal control allows setting a minimum speaker level. An automatic
speaker switching circuit will quiet the speaker when the talk button is
activated.

The KB-701 receives power from the Clear-Com intercom line. The unit
mounts either in a standard four-gang electrical outlet box or in an optional
Clear-Com V-Box. The extra-thick front panel and compact surface-mount
circuitry maintains Clear-Com ruggedness. The intercom channel connects to
a plug-on-screw terminal strip. Male and female three-pin XLR connectors
are provided on the optional V-Box to offer a through connection to the
intercom channel.

function on a TW line, the unit’s operation will remain single channel. Also,
the EB7-4W four-wire daughter board module is available to allow
long-distance connections using separate pairs of wires for send audio and
receive audio.

The KB-701 is compatible with all Clear-Com party-line intercoms.

OPERATION

Normal operation of the KB-701 speaker station only requires access to 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.

FRONT PANEL

The controls and indicators on the KB-701 front panel are shown in Figure
1-1 and are described by the following text.

Figure 1-1: Front Panel

1. Talk Button: The talk button activates the microphone feed to the
intercom channel. The button activates when pressed and deactivates
when released.

The talk button lights amber when the microphone feed to the intercom
channel is on, whether activated locally by pressing the button, or acti­vated remotely from another station using the call signal.

The talk button lights blue to indicate that the microphone feed to the

1-2

intercom line is off, but the station is receiving power.

KB-701 SPEAKER STATION

2. Call Button: Pressing the call button sends a call signal on the intercom
line and causes all the call lights on other stations on the intercom channel
to light.

The call button lights red when a call signal is sent or received on the
intercom line.

3. Speaker: The audio output for the KB-701 device.

4. Volume Control: Turn this control to set the speaker’s required listen
level. This control does not affect the tone alert level or the program input
level.

5. Program Level Control: Adjust the program level control to set the
program audio level heard in the panel speaker.

Note: Forcing the trimpots past their stop points will damage them.

6. Integral Microphone: The microphone for the KB-701 is built into the
front panel.

INTERNAL ADJUSTMENTS AND CONNEC­TIONS

The controls and connectors inside the KB-701 are shown in the following
figure and described by the following text. The controls can be accessed
without completely removing the panel from its wall box or V-Box enclosure
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 to make the controls
accessible as shown in the lower view of Figure 1-2.

7. Call Alert Tone Level Control: This internal control adjusts the volume
of the call alert tone sound. This is normally adjusted when the system is
set up and shouldn’t need to be adjusted during normal operation. This
feature can be disabled by turning the control fully counterclockwise.
An audible tone alert can sound when a call signal is received on the
intercom channel. This can be useful when the operator's attention has
been drawn away from the KB-701 indicator panel. The tone alert will not
sound if a call signal is originated at the KB-701 station.

Note: This feature is automatically turned off if the operating mode of

the KB-701 is set to any setting other than normal.

8. Minimum Volume Control: This control adjusts the minimum setting of
the intercom level control on the front panel. Setting this control can
prevent people from inadvertently turning the intercom level all the way
down. This is normally adjusted when the system is set up and shouldn’t
need to be adjusted during normal operation. This feature can be disabled
by turning the control fully counterclockwise.

9. Option Switches: Three option switches are provided. They should be
configured when the system is set up, but are not changed in normal
operation.

Note: The “on” position of each switch is toward the circuit board and

the “off” position is toward the front panel. A description of the
function of these switches follows.

• Internal Microphone Gain (S-1)— This switch determines the

microphone’s sensitivity. When the switch is in the on position,
talking should be done within 2 ft. (0.61 m) of the front panel. If it is
necessary to talk from a greater distance, the switch should be turned
off. The default position of this switch is in the on position.

• Operating Mode (S-2 and S-3)—These switches work together to

define the operating mode of the KB-701. In modes other than
normal, the call signal from other stations on the same channel
activates the KB-701. Refer to the following table:

KB-701 SPEAKER STATION

• The default position of these switches is in the off position for normal

A

mode, which is the only mode in which the call alert tone functions
operate. In other modes, the call alert tone is automatically disabled to
avoid interference with operation.

Note: Only normal mode may be used when the EB7-4W four-wire option

module is installed.

10. Intercom Line Connection: The KB-701 contains a five-terminal,
plug-on connector for intercom line connection. This connector is
intended to be unplugged from the circuit board when connecting the
intercom line, and then plugged back on when the wiring is completed.
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 --- (NC)

Pin #3 --- Channel A Audio

Pin #4 --- Power

Pin #5 --- Ground (Shield)

11. Program Input: A three-terminal, plug-on connector provides the
program input to the station. Program is fed to the speaker. This level is
controlled by the program level control. If this input is connected to the
stage announce (SA) output of a main station it can be used as a paging
input. Since the level of this input is independently adjustable from the
intercom audio volume, it can be used to override the intercom audio in
all modes except remote listen-page. The program input is also
independent of the mode setting. The pinout of the program input
connector is as follows:

Pin #1 --- Ground (Shield)

Pin #2 --- + Signal

Pin #3 --- - Signal

12. Option Board Jumpers: The two jumper plugs P1 and P3 must be
installed when optional modules are not used. When the optional
EB7-4W or EB7-TW modules are used, both P1 and P3 must be
removed. Save these jumper plugs for possible future use.

Note: The KB-701 will not operate without either the jumper plugs or the

optional modules installed. The orientation of P1 in J1 and P3 in J3
does not matter.
