STEREO MODE

If you will be connecting one or two pair of speakers to the amplifier, place the switch in the “Stereo” position. NOTE: For playing 2 pairs of speakers (A plus B), make sure each speaker has an impedance of 8 ohms or greater.

BRIDGED MODE
When set to “Bridged” mode, the amplifier is a single channel mono amplifier.

BRIDGED MODE- MONO APPLICATION

For bridged mode, playing Right and Left together as mono output, use a Y cable adapter to connect Right and Left RCA signal to the Right (Red) input at MAIN IN. Set the MODE switch to BRIDGED and follow the instructions for bridged speaker connection in the SPEAKER TERMINALS section of this manual.

• NOTE: The AMP210VS supplies 250W in bridged mode, Please verify that your speakers are capable of handling such power to avoid possible damage!

Power Mode
Sets the power on option of the AMP210VS. Set it to Normal for manual power on/off. Set to Auto-On for signal sensing power up. Set to Trigger if the 12V Trigger input is used.

Speaker Zone A Output
Speaker output terminals for zone A. Minimum impedance: 8 ohm bridged or 4 ohm stereo.

Speaker Zone B Output
Speaker output terminals for zone B. Minimum impedance: 8 ohm bridged or 4 ohm stereo.

SPEAKER TERMINALS – STEREO MODE

For stereo output connect the speaker’s positive (red) terminal to the amplifier’s positive (red) terminal, and the speaker’s negative (black) terminal to the amplifier’s negative (black) terminal for each Right and Left speaker.

SPEAKER TERMINALS – BRIDGED MODE

Place the “MODE” switch in the “BRIDGED” position and use both red terminals to connect to the speaker. Connect the speaker’s positive (red) terminal to the amplifier’s red (+) terminal noted next to the bridging mark, and the speaker’s negative (black) terminal to the amplifier’s unmarked positive (red) terminal

• NOTE: Only one zone (A or B) can be bridged. Do not attempt to bridge both A and B speaker terminals! This may result in a lower impedance than the amplifier is designed for and may damage your amplifier. The minimum impedance for the total load connected in bridged mode is 8 ohms.
• NOTE: Use Class 2 wiring for speaker connections. To wire the output connector: 1. Strip the insulation off each speaker wire to expose 3/8″ (10 mm) of bare conductor. 2. Unscrew the output terminal binding post several twists, insert each wire into the correct terminal.

Mains Power : Inlet & Fuse Holder Accepts IEC type line cord. A fuse located in the integrated holder provides safety protection from fault conditions: replace fuse with one of same type and rating only

Mains Voltage Selector: Voltage selection switch is preset to 115V (USA). For use in areas which require 230V contact your dealer. Fuse must be of type and rating marked on amplifier for use at local mains voltage.

APPLICATIONS

STEREO SETUP

In this configuration, the mode switch is set to “Stereo”. Connect the line out jacks from a stereo pre-amplifier or source to the MAIN input jacks of your AMP210VS. Next connect your speakers to the terminals marked “Speaker A” observing proper polarity. Select the “A” speakers using the front panel zone selection buttons. Connect a second (optional) pair of speakers to the terminals marked “Speaker B”. If you are connecting 4 speakers to the AMP210VS they must be8 ohm speakers only. Press A and B together to use both zones.

SETUP FOR MULTIPLE SOURCE

In the multiple sources set up, a distributed audio system is connected to the AMP210VS as a local zone amplifier via the MAIN inputs. Normally the distributed audio system will be the audio source for the AMP210VS. The distributed audio is then passed on to be used by additional zones or sub zones in the distributed system via the MAIN outputs.

The audio output of a local source, such as an MP3 Player, CD, television, computer, etc., is connected to the AMP210VS via the INTERRUTING inputs, and whenever the local source is active its signal will take priority over the distributed audio signal present at MAIN input. However, the distributed audio signal will still be present at the MAIN input. In this circumstance the audio output of the local source will be heard via the AMP210VS. Once the local source is turned off or muted, the AMP210VS will automatically switch back to the distributed audio system as an audio source, assuming the local source remains inactive. There is a delay of up to 6 seconds when switching from INTERRUPTING input back to MAIN inputs.

FAQ’S

• What is the purpose of an amplifier?
  An electrical device called an amplifier boosts a signal’s voltage, current, or power. Wireless communications, broadcasting, and all types of audio equipment employ amplifiers. Either weak-signal amplifiers or power amplifiers can be used to describe them.

• What does ‘amplifier’ mean?
  one that is stronger

• How does an amplifier operate?
  Before it is supplied to the speakers, an amplifier makes a bigger duplicate of the input signal from a source, such as a laptop, turntable, or CD player. Your mains electricity, which is routed straight to the amplifier’s power source, provides the energy needed to do this.

• Is a speaker an amplifier?
  Both speakers and amplifiers produce sound.

• What equipment use amplifiers?
  To raise a signal’s amplitude, amplifiers are used in computers, audio equipment, music equipment, and electrical devices like television and radio receivers.

• How do amplifier circuits work?
  It is a two-port electrical circuit that amplifies signals delivered to its input terminals using electricity from a power source to create signals with correspondingly increased amplitude at the output.

• What is an amplifier of current?
  An electrical component used to multiply the amount of an input signal’s current by a set signal is known as a current amplifier. The following circuit or the device receives this current.

• An amplifier for speakers is what?
  Your source equipment’s low voltage signals are transformed by an amplifier into a signal with sufficient strength to drive a pair of speakers.

• Which amplifier class is the best?
  Class “A” amplifiers are regarded as the best class of amplifier design because, when constructed properly, they have great linearity, high gain, and minimal levels of signal distortion.

• An AC or DC speaker?
  The obvious response to this query is that all speakers use AC to generate audio. The amplifier supplies this AC power. While the amplifier itself is powered by a DC source, the speakers are not directly connected to it. As a result, speakers are considered AC equipment.
