Protection Modes
The AMP-1640 provides three protection modes. Note that the AMP-1640 does not shut down
in a protection mode; only the faulty zone/channel is disabled.
•
Central potential protection mode (LED indication)
The central potential protection mode is the only mode, which activates the Protection
LEDs on the front panel. This mode is more commonly known as the
DC potential
protection mode
and is designed to protect the connected speakers from any DC voltage
that is output from the AMP-1640. When the central potential protection mode is activated,
the LED for that respective channel will be turned on (
Red
). When a channel is in the
central potential protection mode other active channels will remain operational unless they
are in a protection mode. After the fault is fixed, the AMP-1640 will automatically restart the
disabled zone/channel.
•
Speaker short protection mode (no LED indication)
This mode will disable a zone/channel until the fault is fixed. After the fault is fixed, the
AMP-1640 will automatically restart the disabled zone/channel.
•
Overload protection mode (no LED indication)
This mode will disable a zone/channel until the fault is fixed. After the fault is fixed, the
AMP-1640 will automatically restart the disabled zone/channel.
Protection LEDs
The eight zone LEDS indicate the status of each zone, or pair of channels when in the central
potential protection mode. A
Red
LED indicates that the central potential protection mode has
been enabled to protect a zone/channel (see above for description).
Rear Panel
Turn-on Mode Switch
The rear panel turn-on mode switch determines when and how the amplifier will turn on.
This switch provides two options for turning the AMP-1640 on and off.
•
Constant (manual turn-on via the front panel master Power button)
•
3-24 AC/DC Voltage Trigger (External)
Constant
– In this mode the front panel master Power button is in the On position. The
amplifier is always on. The front panel master Power button operates the amplifier.
3 – 24V AC/DC Voltage Trigger
– This mode provides for the following:
•
The master Power button on the front panel must be in the
On
position.
•
The amplifier is off when there is not a 3 - 24V AC or DC voltage applied to the voltage
trigger input.
•
Once the sensing circuitry detects a voltage, all adjacent pairs of amplifier channels that
are receiving an audio signal turn on.
•
Once the voltage stops, the sensing circuit instantly turns the amplifier off.
•
Voltage triggers can be supplied by Savant control platforms, some video projectors, or
some surround sound processors.

Caution
: Do not use a DC wall adapter. The long discharge time of the DC
adapter’s
filter capacitor will delay the turn-off of the amplifier.
Note
: The 3-24 AC/DC Voltage Trigger mode allows you to configure the amplifier to
turn on automatically.
12V Trigger Control Output
This terminal provides a 12V DC signal suitable for triggering an additional Savant AMP-1640
amplifier. This voltage is present only when the amplifier is active or on. When the amplifier
turns off, the 12V signal is off.
Gain
The output level of each channel can be fined tuned using the gain control for each channel on
the rear panel.
120/230 VAC Voltage Selector
The 120/230 VAC Voltage Selector consists of two switches to power the AMP-1640.
Depending on the voltage required,
both
switches must be set to either 120 VAC or 230 VAC.
Important
: The voltage selector is factory set to either 120 VAC or 230 VAC and
secured in position with both locking plates.
DC Voltage Signal Protection
In the event a damaging DC signal becomes present on any of the speaker terminals, the DC
protection circuit shuts down the entire amplifier and the associated red LED under
Protection
illuminates. To reset the amplifier you must set the front panel master Power switch to
Off
and
then
On
.
Cleaning and Maintenance
The internal parts of the AMP-1640 are electronic and require no maintenance. Once a year it
is appropriate to twist the RCA connectors on each input to remove any oxidation and improve
conductivity. You can clean only with dry cloth. Do not use any spray-type, abrasive cleaners
on the amplifier.
