DOLBY PRO LOGIC* (NON-DIGITAL)

–

LINE LEVEL

Use this installation method for Dolby Pro Logic applications (not Dolby Digital, DTS or other digital processing), where the receiver/processor is equipped with a subwoofer output, or a volumecontrolled preamp (line-) level output:

Use RCA-type interconnects to connect the line-level subwoofer outputs on your receiver or amplifier to the line-level inputs on the subwoofer. IMPORTANT: Do not use the LFE input on the subwoofer with Dolby Pro Logic processors.

NOTE: If your receiver or amplifier only has one subwoofer output jack, then you will need to use a Y-connector (not included). Plug the male end of the Y-connector into your receiver or amplifier’s subwoofer output jack, and connect each of the two female ends to separate RCA-type interconnects. Finally, plug the RCA-type interconnects into the linelevel inputs on the subwoofer.

Connect each speaker to the corresponding speaker terminals on your receiver or amplifier.

Make sure your receiver or processor is correctly configured to indicate that the subwoofer is “On.”

Note for advanced users: If your receiver/processor has a built-in low-pass crossover filter for the subwoofer output, you may use the LFE input to bypass the subwoofer’s internal crossover.

Use this installation method for Dolby Digital, DTS or other digital surround processors:

Use the line-level input jack marked “LFE” for the LowFrequency Effects channel.

Connect this jack to the LFE output or subwoofer output on your receiver or amplifier. Connect each speaker to the corresponding speaker terminals on your receiver or amplifier.

Make sure that you have configured your surround sound processor for “Subwoofer On.” Also configure your receiver for 5.1-, 6.1- or

7.1-channel operation as appropriate. The front left, front right, center and rear speakers should all be set to “Small.” If your receiver allows you to set the crossover frequency between the subwoofer and the main speakers, select

120Hz or the setting that is the closest frequency below it.

DOLBY PRO LOGIC (NON-DIGITAL) –SPEAKER LEVEL

Use this installation method for Dolby Pro Logic applications (not Dolby Digital, DTS or other digital processing), where the receiver/processor does not have a subwoofer output, or a volume-controlled preamp (line-) level output:

Connect your receiver or amplifier’s front left and right speaker terminals to the left and right terminals on the subwoofer that are marked “Speaker Level In.” Connect the left and right terminals on the subwoofer that are marked “Speaker Level Out” to the corresponding terminals on the back of your front left and right speakers.

Connect your receiver or amplifier’s center, surround and surround back speaker terminals to the corresponding terminals on the back of your center and surround speakers.

If there is no sound from any of the speakers:

• Check that receiver/amplifier is on and a source is playing.

• Check that the powered subwoofer is plugged in, and its

Power switch å is

switched on (“•” position).

• Check all wires and connections between receiver/ amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured, or touching each other.

• Review proper operation of your receiver/amplifier.

If there is no sound coming from one speaker:

• Check the “Balance” control on your receiver/amplifier.

• Check all wires and connections between receiver/ amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured, or touching each other.

• In Dolby Digital or DTS modes, make sure that the receiver/processor is configured so that the speaker in question is enabled.

• Turn off all electronics and switch the speaker in question with one of the other speakers that is working correctly. Turn everything back on, and determine whether the problem has followed the speaker, or has remained in the same channel. If the problem is in the same channel, the source of the problem is most likely with your receiver or amplifier, and you should consult the

owner’s manual for that product for further information. If the problem has followed the speaker, consult your dealer for further assistance or, if that is not possible, visit www.jbl.com.

If there is no sound from the center speaker:

• Check all wires and connections between receiver/ amplifier and speaker. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured, or touching each other.

• If your receiver/processor is set in Dolby Pro Logic mode, make sure the center speaker is not in phantom mode.

• If your receiver/processor is set in one of the Dolby Digital or DTS

modes, make

sure the receiver/

processor is configured so that the center speaker is enabled.

If the system plays at low volumes but shuts off as volume is increased:

• Check all wires and connections between receiver/ amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured, or touching each other.

• If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier.

If there is low (or no) bass output:

• Make sure the connections to the left and right “Speaker Inputs” have the correct polarity (+ and –).

• Make sure the subwoofer is plugged into an active

electrical outlet

, and is turned on (Power switch å in the “•” position).

• In Dolby Digital or DTS modes, make sure your receiver/processor is configured so that the subwoofer and LFE output are enabled.

If there is no sound from the surround speakers:

• Check all wires and connections between receiver/ amplifier and speakers. Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut or punctured, or touching each other.

• Review proper operation of your receiver/amplifier and its surround sound features.

• Make sure the movie or TV show you are watching is recorded in a surround sound mode. If it is not, check to see whether your receiver/amplifier has other surround modes you may use.

•

In Dolby Digital or DTS modes, make sure your receiver/processor is configured so that the surround speakers are enabled. When five satellites are in use, remember to configure your receiver or processor for

6.1-channel operation, and when all six satellites are in use, configure your receiver or processor for 7.1 channels.

• Review the operation of your DVD player and the jacket of your DVD to make sure that the DVD features the desired Dolby Digital or DTS mode, and that you have properly selected that mode using both the DVD player’s menu and the DVD disc’s menu.

SUB200 Test Set Up and Procedure

Equipment needed:

• Function/signal generator/sweep generator

• Integrated Amplifier

• Multimeter

• Speaker cables

General Unit Function (UUT = Unit Under Test)

1) From the signal generator, connect one line level (RCA) cable to the Subwoofer Line Level Input jacks L/R on the UUT. Use a Y-cable from a mono source if necessary to connect to both inputs. Do not connect to the single LFE input.

2) Turn the LEVEL control on the UUT to completely counterclockwise (MIN).

3) Turn on generator; adjust to 100mV, 50 Hz.

4) Plug in UUT; turn the power switch ON. LED should switch from Red to Green. Turn LEVEL control full clockwise (MAX)

5) LED should Green; immediate and vigorous bass response should be heard and felt from port tube opening.

6) Turn off generator, turn LEVEL control full counterclockwise (MIN), and disconnect RCA cable.

7) Connect one pair

of speaker cables to Speaker Level input terminal (IN) on UUT. Cables should be

connected to an integrated amplifier fed by the signal generator.

8) Turn on generator and adjust so that speaker level input at the amplifier is 2.0V, 50 Hz. Turn LEVEL control full clockwise (MAX).

9) Green LED should light; immediate and vigorous bass response should be heard and felt from the port tube opening.

Sweep Function

1) Follow steps 6-8 above, using a sweep generator as a signal source.

2) Sweep generator from 20Hz to 300Hz. Listen to the cabinet and drivers for any rattles, clicks, buzzes or any other noises. If any unusual noises are heard, remove woofers and test.

Driver Function

1) Remove woofer from cabinet (instructions on exploded view drawing); detach + and - wire clips.

2) Check DC resistance of woofer; it should be 3.4 ohms ±10%

3) Connect a pair of speaker cables to driver terminals. Cables should be connected to an integrated amplifier fed by a signal generator. Turn on generator and adjust so that speaker level output is 5.0V.

4) Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises.
