Congratulations!

With the purchase at THE BEAM BOX by BIC you have taken an
important step towards realtztng the lull lidelity and quality oi sound
which your FM receiver or tuner can deliver. THE BEAM BOX is

a truly unique product designed to replace inetlective Indoor FM
antennas such as twinalead dipole wires often supplied with FM
sets Cumbersome rabbit-ears" antennas, ineffective and danger.
ous wall-outlet antennas and, in many cases, outdoor antennas

that are either ineffective for FM reception or cannot be readily
oriented tor best FM reception

THE BEAM BOX IS a high fidelity component Once properly
installed, it can be electronically oriented to pick up signals from
stations located anywhere in your listening area Since it is highly
directional, it picks up desired Signals while rejecting undesrred
signal rellections that cause multipatn distortion increase in back-
ground norse and even less ol good stereo channel separation
In addition to its electronic orientation capabitrty, THE BEAM BOX
incorporates a completely electronic tuning crrcun which covers
the entire FM trequenc, band from 88 ivle to 108 MHz. By en»
abling you to tune preeise y to toe Signals oi your choice, THE
BEAM BOX helps to retest unwanted interlering Signals oi other
FM frequencies which might adversely altect the sound quality of
the stations you actualgr wan: to hear THE BEAM BOX is much
more than a precrsren indoor FM antenna It is the only product
available that actually improves many of the perlormarice char-
acteristics ot your tuner or TCCElVET regardless ol its cost. Since
THE BEAM BOX is a preCiSion e!ectronic product. we urge you to
read the entire contents oi this manual betore attempting to con
nect or use it. You Will find that installation and operanon are
quite Simple Heres to better FM lidelity

Installation

THE BEAM BOX will work virtually at any location in your high
fidelity system. For optimum performance. follow these guidelines:
a. THE BEAM BOX should not be placed next to a large metal ob-
ject, such as a radiator. metal cabinet, etc.

b. THE BEAM BOX should not be placed on top of a receiver or
tuner that contains vent holes on top. This will not affect the antenna.
but could restrict the venting of the receiver or tuner.

0. Since you will want to observe the tuning meter on your receiver
or tuner when using THE BEAM BOX; tor convenience sake. it
should be as close to the receiver or tuner as possible,

Wiring
We supply a length at 300 Ohm twin lead with spade connectors at
each end. Attach one end of the twin lead to the two screw terminals
labelled 300 Ohms at the rear of THE BEAM BOX. Attach the other
end oi the twin lead to the 300 Ohm connection at the rear of your
receiver or tuner. (See Diagram ol Normal installation)

It the connections at the rear of your receiver or tuner are press-in
type (not screws), cut oil the spade lugs, strip back the wire and
insert the wire in the press~in connector.

Alternate Installation

It you are in a very high interlerence area. where. for example,
automotive ignition norse may be a problem, it may be necessary
to use shielded cable (either 75 Ohm or 300 Ohm)

The FMt 0 contains an "F" connector for 75 Ohm trans~
missmn line. (See Diagram oi Alternate Installation-FMiO)

The Diagram (Alternate installation-FMS) shows the various
connections tor use of these type cables on the Model FMS. When
75 Ohm cable is used a matching translormer Will be necessary.

Contact your local electronics dealer lor "F" connectors. 75
Ohm and 300 Ohm cable necessary tor these hook-ups

~=VAILI m m

A. TUNING CONTROL. This control is used to tine-tune THE BEAM
BOX so that it is most sensitive to those lrequencies that you want
to receive. The control covers the entire FM frequency range lrom
88 Megahertz to 108 Megahertz.

B. BANDWIDTH CONTROL. This two-position switch selects either
broad (2) or sharp (linite) tuning (1). as indicated by the two dia-
grams located directly above the control knob,

C DIRECTIONAL CONTROL. This control is used to electronically
orient the antenna elements contained in THE BEAM BOX. The
arrows appearing in the blocks (boxes 3 thru 6). just above the con-
trol knob. indicate the directions from which signals will be most
favorably received as you face the front panel
of THE BEAM BOX. Thus, when the control

is switched so that its pointer lines up as in
the diagram, best signal reception will occur
for signals arriving from directly in front of you
or from directly behind you. The tour avail-
able electronically orientatable positions of
this control cover a complete 360 degree
circle, insuring best reception of all FM signals, regardless of
where the station transmitters in your area are located.

Initial Control Settings

Alter you have installed THE BEAM BOX and wired it to the antenna
terminals of your FM tuner or receiver. start by setting THE BEAM
BOX controls as follows:

1. Set the TUNING CONTROL (A), to approximately its mid-point of
rotation, half way between the 88 MHz and 108 MHz calibration
notations.

2. Set the BANDWIDTH CONTROL (B), to the broad position (2), as
indicated by the diagram.

3. Set the DIRECTIONAL CONTROL arbitrarily.
tor any of the tour available electronic orien-
tation directions (boxes 3 thru 6).

Turn on your receiver or tuner, adjusting
controls of your system tor normal listening
levels, Tune your receiver or tuner to the ire-
quency at a station you wish to receive. It your
tuner or receiver is equipped with a center-ol-channel tuning meter
or any other center-tuning indicator. make sure that you have tuned
the receiver ortuner to the exact center ol channel, as indicated by
