PLANNING YOUR SYSTEM
Choosing Proper Placement and Setup
The Beta ES250 surround speaker can be used in side or rear
channel applications.Please refer to the placement and setup
method for your application. The first step is to determine the
application for which your Beta ES250 surround speaker will
be used.
If you are using the Beta ES250 for surround channels in a
5-channel home theater system or for side channels in a 6or 7-channel home theater system (Application 1),please
follow the directions below.
If you are using the Beta ES250 as a rear speaker in a 6- or 7channel home theater system (Application 2),please follow the
directions on page 3.
The Beta ES250 also possesses the unique capacity to behave as
two distinct loudspeakers from one enclosure.This allows you to
use a single ES250 for both the left and right rear speakers in a
7-channel system.If you are using the Beta ES250 this way,
please follow the instructions on page 3 (Application 3).
Placement (Application 1)
When using the Beta ES250 for the surround channels in a
5-channel home theater system or for side channels in a 6or 7-channel home theater system,refer to Figures 1 and 2.
The speakers should be placed perpendicular to or slightly
behind the primary listening location,as shown.
Setting the Surround Configuration Selector
It is generally recommended that the selectable surround mode
configuration be set to Bipole.This will provide a large ambient
surround sound field while allowing for precise localization of
sound effects that the filmmaker has placed in the surround
tracks.
If the side walls on which the speaker will be mounted are more
than about 14' (4.3m) from the listening position,setting the
Surround Mode Configuration Switch to Monopole may offer
improved performance.It is also recommended that the Monopole
position be selected if the speakers will be mounted close to a
corner,as shown in Figure 2.
If you are using a receiver/processor with a THX
®
surround mode
and have selected the THX surround mode,it may be beneficial to
use the Dipole setting. This is a matter of personal preference
and may change depending on the individual film soundtrack.It
is also recommended that the Dipole setting be used with older
recordings that are only recorded with a Dolby* Pro Logic* (not
the newer Dolby Digital) soundtrack.

IMPORTANT NOTE:The set of drivers closer to the monopole
setting indicator in Figure 3 should be installed toward the front
of the room.It does not matter whether the tweeter is positioned
above or below the woofer.This will ensure proper operation
and performance should the Monopole or Dipole position on
the surround mode configuration switch be selected.

Placement (Application 2)
When using the Beta ES250 as a rear speaker(s) in a 6- or
7-channel home theater system,refer to Figures 4 and 5.
The speaker(s) should be mounted on the rear wall facing the
listening area,between the side channel speakers.If you are
using one rear speaker,it should be mounted as close as
possible to the center of the listening area.When using two
rear speakers,they should be spaced evenly within the width
of the listening area.
Setting the Surround Configuration Selector
When used as a rear channel speaker in a 6- or 7-channel
system,it is recommended that the Surround Mode Configuration
Switch be set to Bipole,as shown in Figure 6.
Placement (Application 3)
The Beta ES250 also possesses the unique capacity to behave
as two distinct loudspeakers from one enclosure.This allows you
to use a single ES250 for both the left and right rear speakers
in a 7-channel system.
To utilize the ES250 in this application, follow these simple steps:
1.Decide where you want to mount the speaker.Ideally,it should
be mounted in the center of the rear wall,similar to how it would
be mounted in a 6-channel system (Fig.4).
2.Loosen the terminals and remove the strapping bars that
connect the two sets of terminals (Fig.9).
3. To ensure proper left/right connections,make sure that the
speaker is in the “upright”position.The label on the back of
the speaker should be readable,not upside down.
4.Connect the speaker wire for the RIGHT REAR speaker to
the top set of terminals (Fig.10).
5.Connect the speaker wire for the LEFT REAR speaker to
the bottom set of terminals (Fig.10).
6.Set the mode configuration switch to the Bipole position (Fig.6).
