Jensen JHT525 owner manual Connecting the Subwoofer, Option 2 Connection with an audio cable

Power Cord – Plug the power cord into an AC wall outlet or other AC outlet capable of supplying at least 200 Watts.

Level Control/Power Switch – Turns the AC supply completely OFF or balances the loudness of the Subwoofer relative to the Front speakers and compensates for room effects on the Subwoofer’s output.

Power indicator LED – This LED is unlit when the AC power switch is OFF. It glows green when the Subwoofer is on.

FUSE 250V 1A – This fuse protects against internal and external faults. If the POWER switch is ON and the power indicator LED is unlit, unplug the power cord from the AC outlet and check the fuse by unscrewing the center piece from the holder.

IMPORTANT – If the fuse is blown, replace it only with a fuse of the same type and current rating.

L, R SPEAKER-IN and OUT Terminals – See Connection Option 1. These terminals are for making connections using speaker wire. If you use this option, do not use Option 2.

LINE In Jack – See Connection Option 2. This jack is for input connection using audio cables. If you use this option, do not use Option 1.

CONNECTING THE SUBWOOFER

IMPORTANT – When you make connections, make sure that the power switches of all components, including the Subwoofer, are OFF.

Speaker wire Typical speaker wire has a pair of separate conductors with insulating jackets that are molded together. We recommend that you use 16-gauge speaker wire for hooking your Receiver to your Front speak- ers. To make connections to the Subwoofer in parallel with the Front speakers easier, the speaker wire con- necting the Receiver to the Subwoofer can be smaller (high- er gauge number), since the Subwoofer does not draw large amounts of power through these wires.

Polarity All speakers in a system must be connected with the same polarity. Speaker wire is marked for polarity so that you can identify which wire in the pair is which. Polarity is shown by a color stripe on the insulation, by ridges molded into the insulation, or by the colors of the wires – one copper and one silver. Strip the insulation from speaker wire ends to reveal the bare conductors before connecting to Receiver, Subwoofer or Speaker terminals.

IMPORTANT – Always connect the red (+) terminal on the Receiver to the red (+) terminal on the Subwoofer, and the black (-) terminal on the Receiver to the black (-) terminal on the Subwoofer. The same is true for hooking the Receiver outputs to the Front speakers: red (+) to red (+), and black (-) to black (-).

IMPORTANT: Use Option 1 or Option 2 (not both).

Connect speaker wires from the Receiver’s front left and right speaker outputs to the Subwoofer’s Speaker Level-In connections. Connect left channel to left input and right channel to right input. You have the option of connecting your main speakers to the speaker B outputs on your Receiver, if it is so equipped. You also have the option of con- necting your main speakers using the connections on the Subwoofer. This will pass the audio signal to your main speakers, except the low bass which will be produced by your Subwoofer. To use this connection option, connect your main speakers to the right and left outputs on the Subwoofer (see illustration for Option 1). Be sure you take care to maintain proper signal polarity, red to red and black to black.

Option 2 – Connection with an audio cable

RECEIVER

Subwoofer

Output

Line In

SUBWOOFER

This connection uses a low level sub signal. This is usually found on Receivers equipped with Dolby Digital™ decoding. Locate the Subwoofer output on the back of your receiver. Using a standard RCA cable connect the Subwoofer output on the back of your Receiver to the Line-In on the back of the Subwoofer.
