JL Audio J2360.2 When bridged, the amplifier, Do not do this, Servicing your Amplifier

! IMPORTANT

When bridged, the amplifier

will deliver 360W x 1 into a 4 ohm load or 220W x 1 into an 8 ohm load. Operating a pair of bridged channels into a load lower than 4 ohms is not recommended.

Because a bridged pair of channels requires that both channels receive input, you need to connect both left and right inputs to the source unit. Connection of only one input will result in reduced power output, increased distortion and can cause the amplifier to overheat.

Do not do this!

When the J2-360.2 is operating in bridged mode, the output will be in mono (only one channel). This mono channel can contain right channel only information, left channel only information or the sum of the information from both the right and left channels. In order to achieve one of these options, configure the inputs to that pair of channels in one of these two ways:

1)Left Channel Only or Right Channel Only Information: If you wish to send a left-only or right-only signal to the J2-360.2, use a

“Y-Adaptor” to split the single channel signal into both left and right RCA inputs. This option is useful when using the J2-360.2 to drive left channel speakers only and another

J2-360.2 to drive right channel speakers only.

2)Left + Right Channel Information: When bridged and fed by a stereo input, the J2-360.2 will automatically combine the left and right input channels into a summed mono

(left + right) channel. This option is useful when using a the J2-360.2 to drive a subwoofer system or a summed mono center channel.

AMPLIFIER Status Indicator Lights & Protection Circuitry

There are two status indicator lights on the control panel of the amplifier.

Power

Protect

￿ +9dB ass Boost

1)Power(Green): lights to indicate that the amplifier is turned on and operating normally. Located at the far left of the control panel.

2)Protect(Red): Indicates that the amplifier protection circuitry has been activated

to prevent product failure due to thermal overload, short-circuit or a dangerously low impedance connected to the amplifier outputs. Connecting the speaker outputs to an impedance lower than 2 ohms stereo (4 ohms bridged) will cause this protection mode to activate. When this protection mode is activated, the amplifier will shut down to protect its circuitry. When the problem is corrected, the amplifier will return to normal operation and the “Protect” LED will shut off.

Servicing your Amplifier

If your amplifier fails or malfunctions, please return it to your authorized JL Audio dealer so that it may be sent in to JL Audio for service. There are no user serviceable parts or fuses inside the amplifier. The unique nature of the circuitry in the JL Audio amplifiers requires specifically trained service personnel. Do not attempt

to service the amplifier yourself or through unauthorized repair facilities. This will not only void the warranty, but may result in the creation of more problems within the amplifier.

If you have any questions about the installation or setup of the amplifier not covered in this manual, please contact your dealer or technical support.
