PLACEMENT:

Keep your Sonamp®Cinema 260 out of direct sunlight and away
from windows where rain may enter. It should be placed away
from heat sources such as hot air ducts or radiators; do not
place the unit directly on a pile carpet that could interfere with
air flow into its bottom vent opening. If you stack your
components, it is better to place the Sonamp above or alongside
your other components; when driven hard, the unit itself may
create a little heat and disturb components stacked on top of it.
If it is inside a cabinet, allow ample ventilation.Very sensitive
low level sources might pick up some hum radiating from its
enormous power supply.

CONNECTING THE SONAMP CINEMA 260

The Sonamp Cinema 260 is specially designed to drive
subwoofers. Connect the subwoofer output interconnect to the
left channel input jack on the rear of the Sonamp Cinema 260.
If the source preamplifier has no dedicated subwoofer output,
use a pair of interconnect cables from the preamp out to the left
and right input jacks of the Sonamp Cinema 260.

If no line level output is available to drive the subwoofer, use a
Sonance OP-3 to convert high level speaker output to the
appropriate level for input to the Sonamp Cinema 260.Connect
subwoofer speaker wires to the right and left speaker terminals
on the back of the amplifier.

NOTES: Polarity of speaker wires is critical. All positive leads
(+) must be attached to red connectors throughout the system.

Since the Sonamp Cinema 260 subwoofer amplifier sends a
monaural signal to both speakers,either speaker (right or left)
may be driven by either amplifier channel.

The Sonamp Cinema 260 subwoofer amplifier is designed to
drive one speaker per pair of binding posts. Connecting
additional speakers in parallel may cause damage to the
speakers and amplifier.

Do not tie amplifier output (+) terminals together and run a
single 2 conductor to the two subwoofers. Each amplifier
channel requires separate positive (+) and negative (-)
conductors, 4 total for each amplifier and two subwoofer
modules.(See diagram 2)

AMPLIFIER SETTINGS

Some experimentation will be necessary to achieve the best
possible integration of the Cinema SUBs with the other speakers
in the system. Start with the following settings on the Sonamp
Cinema 260:

• FREQUENCY: fully clockwise, highest crossover frequency

• PHASE: down, 0,normal phase setting

• LEVEL: 12:00

The 12:00 level setting is correct for most Dolby

®

AC-3 and

THX

®

processors.

FRONT PANEL CONTROLS

To achieve smooth transition between the subwoofers and
other drivers,it may be useful to employ test tones available on
compact disc and a sound pressure level meter. Inexpensive
SPL meters are available from Radio Shack stores. Some
receivers/processors can produce a pink noise signal for speaker
calibration. Other test DVDs are available. Note: Sine wave test
tones can damage your Cinema speakers and should only be used
at low volume levels for short periods.
