Sonance CINEMA 260 - Manual (Page 3)

Always take SPL readings from ear level at the
listening position.
Receivers/processors provide a special facility to calibrate
subwoofers.When installing the Cinema SUB System with such
a receiver/processor, follow the receiver/processor’s instruc-
tions for calibrating subwoofer output.
When used in conjunction with some components, the bass
response of the Cinema SUBs will be greater with the phase
switch in the down position. Listen to music with
significant bass content with the switch in each position to
determine the correct setting for your system. Sitting in the
normal listening position, listen while a friend changes the
phase switch position. The audibly louder setting is correct.
Alternately, use an SPL meter to determine which setting
produces greater output in the 75-125 Hz range.
If you experience buzzing or rattling during strong bass
passages, it may be necessary to relocate or remove items in the
listening room which become excited by the high energy levels
reproduced by your Cinema SUBs.
MAKING CONNECTIONS:
Before making any signal or speaker connection, make sure
your power amplifier is turned off and unplugged. When
making connections, make sure there is no strain or tension on
input leads or speaker wires that could cause them to pull loose
in the future.
Looping Jacks
Your Sonamp Cinema 260 provides a pair of RCA output jacks
which duplicate the input signal. These facilitate connection of
additional subwoofer systems from a single source component.
With only a single input cable you can link or “loop” amplifiers
without messy Y-cord adapters. Two input cables are required
when using Left and Right Inputs.
Use good wire
For best bass response, and minimum power loss, you should
never use less than 14AWG speaker wire - or it will constrict the
dynamics and deteriorate bass response. We recommend use
of premium Sonance speaker cable. You may also wish
to experiment with audiophile-grade speaker wire and
interconnects, but be sure to check local codes governing wire
that may be installed in walls or ceilings. Each brand of wire will
have a different characteristic sound and some may be more
compatible with the sonic “signature” of your various
components.Your Cinema 260 is stable with any reputable brand
of wire.
AC Line cord
You can plug this into a wall socket or an AC outlet on your
preamplifier. Make sure your preamp outlet rating is equal to or
greater than the Sonamp's power consumption rating. If you do
not plan to use the automatic turn on/off feature, you will
probably want to use a switched AC outlet that is turned on and
off by your preamp's power button. If you choose to use the
Auto Turn on/off feature, you must leave the Sonamp plugged
into an unswitched AC outlet that is always "live" even when the
preamp is turned off.
If you are installing the Cinema 260 in a remote zone, you may
plug it into the closest AC wall socket that is always “live”.
Caution: To prevent electric shock, match wide blade of plug to
wide slot, fully insert.
Attention: Pour evitar les chocs electriques, introduire la lame
la plus large de la fiche dans la borne correspondante de la prise
et pousser jusqu'au fond.
Use only a heavy-duty extension cord, if required, to avoid
starving the amplifier of all current necessary for full
power operation.
OPERATING THE SONAMP CINEMA 260
The Sonamp Cinema 260 has an ingenious and very sophisticated
Auto-On turn on/off circuit. Please read these instructions
carefully to facilitate correct operating procedures.
Power Switch
Press the power switch once to the “in” position to turn on.
Press again to the "out" position to turn it off. Leave the button
in its inner position when using the Auto-On turn on/off
feature. The amplifier will switch its power on automatically
when there is a musical signal present at its input jacks.
Auto-On
Any audio signal arriving at the “left” input jack will trigger
automatic turn on circuitry to activate the unit for
operation. A green LED on the front panel marked “Active”
indicates that the amplifier is operational.
The amplifier will remain on after the audio signal has ceased
for approximately 3 minutes. This provides ample time to
prevent erratic operation from pauses between musical
passages or while changing sources. With this feature there is
no limit to where you can place the Cinema 260.
Auto-On Defeat (located on rear panel)
If the Auto-On turn on/off feature is not required, it can be
defeated by moving the rear panel switch to its “off ” position.
Use a small flat-bladed screwdriver to move the recessed
switch. Do not apply excessive force. Now the Cinema 260
power switch will function conventionally and the amplifier
will turn on and off from a switched AC outlet on your preamp
or other source component.
Power LED (red)
This LED indicates that the AC power line cord is plugged into
a live AC outlet. If the main AC line fuse ever opens, this LED
will go out. To use the Auto-On feature, this LED must remain
