Dolby® Digital or DTS® (or Other Digital Surround Mode) Connection Use this installation method for dolby digital, dts or other digital surround processors:

Use the line-level input jack marked SUB (6) for the low-frequency effects channel.
Connect this jack to the subwoofer output or LFE output on your receiver or amplifier.
Connect each speaker to the corresponding speaker terminals on your receiver or amplifier.

Make sure you’ve configured your surround sound processor for “Subwoofer On.” The front left, front right, center and surround speakers should all be set to “Small.”
When all connections have been made, plug the AC power cord on the subwoofer into an AC outlet.

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 volume controlled preamp (line-) level output:
Use the supplied RCA-type interconnect cable to connect the line-level subwoofer output on your receiver or amplifier to either the left or right Line-Level Full-Range Input (7) on the SUB-TS11 subwoofer.
Use both the left and right inputs on the subwoofer if your receiver or processor has both left and right line-level outputs. In that case, you will need to supply a second interconnect cable.
If your receiver is equipped with line-level outputs but does not have a separate subwoofer output, use a Y-adapter (not supplied) to bridge the receiver’s preamp output to the main amp input for that channel, and connect the long end of the adapter to the corresponding line-level input on the SUB-TS11.
IMPORTANT: Do not use the SUB Input (6) on the subwoofer with Dolby Pro Logic processors.
If your receiver/processor has a built-in lowpass-crossover filter for the subwoofer output, you may use the SUB Input (6) to bypass the subwoofer’s internal crossover.
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.” The front left, front right, center and surround speakers should all be set to “Small.”
When all connections have been made, plug the AC power cord on the subwoofer into an AC outlet.

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 volumecontrolled preamp (line-) level output:
Connect your receiver or amplifier’s front left and right speaker terminals to the left and right Speaker-Level Input (9) terminals on the SUB-TS11 subwoofer that are marked “High Level In.” Connect the left and right Speaker-Level Output (8) terminals on the SUB-TS11 subwoofer that are marked “High Level Out” to the corresponding terminals on the back of your front left and right speakers.
Connect your receiver or amplifier’s center, and surround left and right speaker terminals to the corresponding terminals on the back of your center, and surround left and right speakers.
When all connections have been made, plug the AC power cord on the subwoofer into an AC outlet.

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, purple SUB input.
2) Turn on generator; adjust to 60mV, 50 Hz.
3) Plug in UUT; turn the power switch ON. Turn LEVEL control full clockwise (MAX)
4) LED should turn from Amber to Blue (on top of UUT); immediate and vigorous bass response should be heard and felt from port tube opening.
5) Turn off generator, turn LEVEL control full counterclockwise (MIN), and disconnect RCA cable.
6) 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.
7) Turn on generator and adjust so that speaker level input at the amplifier is 1.2V, 50 Hz. Turn LEVEL control full clockwise.
8) LED should turn from Amber to Blue; 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; detach + and - wire clips.
2) Check DC resistance of woofer; it should be 2.8 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.
