The AMP-1640-20/1640I-20 Quick Reference Guide provides all the steps necessary to get
the Savant AMP-1640 Multi-channel amplifier up and running. Note that this guide supports
the following AMP-1640 units:
• AMP-1640-20 (North America)
• AMP-1640I-20 (International)
The AMP-1640 is an ultra-efficient Class D power amplifier delivering 16 channels (8 zones) of
reliable, affordable, feature-rich amplification rated at 40 watts per channel (WPC) at 8 ohms
and 50 WPC at 4 ohms. The AMP-1640 is housed in a 3U rack-space metal enclosure.
The AMP-1640 is an ideal eight-zone multi-room music system, as shown below, when paired
with a Savant multi-room audio solution. A multi-room distributed audio solution is defined by
how many listening zones it has. Within a listening zone you can only listen to one audio
source (Internet Radio, CD, Music Server, etc.) at a time.
An audio zone can consist of a single room or a group of rooms. When designing your
distributed audio system, take into account who will use the system and when they will use it.
For instance, you may wire your den for background music and your living room for surround
sound.
A multi-zone system allows different sources to be heard in each of the zones, simultaneously.
The diagram below shows four audio sources connected to the Savant SmartAudio platform
with 4 stereo preamps and 8 stereo outputs connected to the AMP-1640 for a 4 x 8 audio
distribution solution.

Installation
The AMP-1640 should be placed on a solid flat surface like a table or shelf or in an audio/video
equipment rack. It should be placed upright so that its weight rests on the unit’s four feet
(removable).
Ventilation
The AMP-1640 must be provided with adequate ventilation for proper cooling. When installing
the AMP-1640 in a cabinet, be sure that the rear of the cabinet is open to adequate air to
provide proper cooling. Be sure to leave a minimum of 3 inches clearance above and behind
the amplifier and at least 2 inches on each side. If installed in a rack, active thermal
management (such as rack fans) is recommended.
Caution: Do not block the ventilation holes on the sides and bottom of the AMP-1640.
Speaker Connectivity
When designing your system specify four to eight ohm speakers.
Cable and Wire
The AMP-1640 has multiple connections on the back panel. Savant recommends that you
clearly label all the input cables and speaker wires. Label the cables and wires with their
destination or source, rather than which terminal of the AMP-1640 they are connected to; it will
be easier to reconfigure your system in the future.
The AMP-1640 connects to your Savant multi-room audio solution via shielded line level audio
cables with RCA phono plugs. Use high quality RCA cables to connect the multi-room audio to
the amplifier inputs.
The AMP-1640 connects to your speakers using 2-conductor speaker wire. For most
applications, Savant recommends using 16 or 18 gauge wire. For wiring runs longer than 80
feet Savant recommends using 14-gauge wire. Each channel features a removable screw
terminal speaker connection for easy installation in tight spaces. The terminal connector can
accommodate up to 14-gauge stranded speaker wire.
Speaker Wire Connections
Caution: All speaker wire connections must be made with the amplifier off.
Bare Speaker Wire – Split the speaker wire insulation so that at least two inches of each
conductor are separated. Strip 1/4 inch of insulation from the end of each conductor of the
speaker wire. Twist the strands of speaker wire together and insert them into the appropriate
screw terminal speaker connection.
Caution: Do not allow a single strand of wire to touch the amplifier chassis or another
connector.
Line Level Source Inputs
Caution: The amplifier must be off whenever you make changes to the input
connections.
Savant recommends labeling all of the interconnecting cables to the sources they connect to
(for example, CD players). Use quality audio patch cables with RCA phono plugs attached to
the ends. Connect the sources by inserting the RCA plug into the amplifier’s RCA jacks.
Connect the outputs from your sources to the inputs on the amplifier.
Caution: Remember never connect a source or preamplifier’s input to the inputs of the
AMP-1640 directly.
AC Power Plug Connection
The last connection made should be the AC power using a standard IEC 3-pole detachable
power cord. Plug the attached power plug into a correctly grounded 120V 60 Hz (AMP-1640-
20) or 230V 50 Hz (AMP-1640I-20) wall outlet.
Front Panel
Power LED
The Power LED indicates that the AC power cord is plugged into a working AC power surge
protected receptacle. When the Power LED is Red, the amplifier is in Standby mode, and
when the Power LED is Green the amplifier is On.
Power Button (Master)
The Power button is the master power switch. No matter which turn-on mode you have
selected, the Power button will turn off all circuitry—including the sensing circuitry. If you will
be away and/or would like to reduce power consumption while you are away, set the Power
button to Off (button is out). When you want to return to normal operation, set the Power
button to On (button is in).
