Polarity
It is important to observe correct polarity when using in stereo
mode.One side of the speaker lead will have some sort of mark,
either printing, a raised ridge on the insulation or different
color of conductor. This permits you to know which wire you
had connected to the + and which to the - speaker terminals so
you can repeat these connections at the power
amplifier terminals.
Multiple Speaker Hookup
The Sonamp
®
2120T is stable into low impedances. If you are in
doubt about your specific impedance load, consult your dealer or
Sonance Technical Service.
To connect more than one pair of speakers to the Sonamp 2120T,
you will need to connect the speaker wires from each speaker in
parallel. The safest and most efficient way to do this is to use
dual-banana plug connectors which are plugged into each other,
end-to-end. If you are connecting bare wires from each pair of
speakers together, we recommend you make this junction at a
point that is not immediately at the speaker terminals. This is
because each joined bundle of wires will be too thick to fit into its
speaker terminals and you run a risk of a short circuit between +
and - terminals. You may use a Sonance SS6 or SS4
speaker selector.
Use good wire
For best results, and minimum power loss, you should never
use thin gauge speaker wire - it will constrict the sound 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
Sonamp 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 Sonamp 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 2120T
The Sonamp 2120T 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 Sonamp's 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 Sonamp. Here are a few
installation possibilities:
• Local room system coupled with a multi-CD changer
• Surround sound front,side, or rear channels
• Multi-room, multi-source control systems
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 Sonamp power
switch will function conventionally and the Sonamp will turn
on and off from a switched AC outlet on your preamp or other
source component.
Level Controls
Front panel level controls are recessed for adjustment by
screwdriver only. This prevents accidental tampering with
levels. Use level controls to adjust the left-right channel balance
to match the listening area to speaker placement in the zone
powered by the Sonamp. You may also adjust levels to limit
maximum safe gain to protect the speaker or to optimize the
signal to noise ratios between the source components and
amplifier. Many volume controls, on source components, are
overly sensitive near their minimum positions; by reducing the
Sonamp input level control settings, you “compel” the source
component volume control to operate up higher, in its more
uniform adjustment range.
The Sonamp level controls can also determine the maximum
level in a speaker volume control system (such as the VC60's
and 30's) to prevent transformer saturation, distortion
or burn-out.
If using the Sonamp 2120T with THX
®
calibrated 5.1
processors, set the level controls to maximum clockwise
rotation in order to to take full advantage of correct SPL setting
of the processor.
