MODE SWITCH

To the right of the Master Level controls is a switch labeled “Mode” with

“Stereo” and “Bridged” as options. If you will be connecting one or two pair

of speakers to the ampliﬁer, place the switch in the “Stereo” position.

NOTE: If you are using the AMP210/310 in stereo mode, with 2 sets of

speakers (A and B), make sure each speaker has an impedance of 8 ohms

or greater.

When used in “Bridged” mode, the ampliﬁer is a single channel Mono

ampliﬁer.

If you will be using a pair of channels to power a single mono speaker, place

the switch in the “Bridged” position, and be sure to read the section titled

“Speaker Terminals” below.

While the ampliﬁer operates in bridged mode you are required to have

the Left input connected to the ampliﬁer only. The ampliﬁer will use

this signal to create your Mono source.

NOTE: The AMP210 supplies 250W in bridged mode, while the AMP310

supplies 450W in bridged mode. Please verify that your speakers are capable

of handling such power to avoid possible damage!

SPEAKER TERMINALS

Terminals are provided for “A” and “B” pairs of speakers for each channel. If

you will be using the ampliﬁer as a stereo ampliﬁer (i.e. not a bridged ampliﬁer),

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 (immediately beside the positive terminal).

NOTE: Use the appropriate gauge speaker wire when connecting speakers

to the AMP210/310.

If using one pair of channels bridged, place the “Mode” switch in the “Bridged”

position and use both RED terminals to connect to the speaker.

When in “Bridged” mode make sure to connect the speaker’s negative

(black) terminal to the ampliﬁer’s positive (red) terminal of the left channel and

the speaker’s positive (red) terminal to the ampliﬁer’s positive (red) terminal of

the right channel.

NOTE: Only one pair of channels can be bridged together. Do not attempt to

bridge both A & B speaker terminals, as this may result in a lower impedance

than the ampliﬁer is designed to accommodate and may damage your

ampliﬁer. The minimum impedance for the total load connected to a pair of

channels in the bridged mode is 8 ohms.

MAINS POWER INLET/FUSE/

VOLTAGE SELECTOR

Power inlet accepts the IEC type line cord supplied with the ampliﬁer. A fuse

in the integrated holder provides safety protection from fault conditions:

replace fuse with one of same type and rating only.

This ampliﬁer is conﬁgured for operation at 115V. (North America)

The AMP210/310 can be conﬁgured for operation from either 115V ~60Hz

or 230V ~50Hz AC mains. Installed mains fuse must be of type and rating

marked on ampliﬁer corresponding to conﬁgured AC mains voltage.

Should you wish to conﬁgure the AMP210/310 for use at 230V ~50Hz

please contact your dealer or distributor.

LIGHT BAR DISPLAY

Light Bar Display

This switch controls the lighted bars on the front of the amplifier. These bars

light red when the amplifier is in operation. If the amplifier is visible, and a low

light setting is desired, use this switch to turn off the light bars. The other LED

indicators on the front panel as well as the power button lighted ring are not

affected by this control.
