OWNER’S MANUAL
12 MODE SWITCH
Mode
Stereo Bridged
Figure 8. Mode Select 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!
15 & 16 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.

19 LIGHT BAR DISPLAY
Light Bar Display
On Off
Figure 9. Light Bar Display Control
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.

Speaker B
Figure 10. Speaker Terminals
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.
17 & 18 | 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.
