Connections

Checking Your Amplifier
Before connecting this unit to your amplifier (or receiver), check what types of connecting terminals your amplifier has. Follow the instructions below to find a proper connection method for your equipment. Illustrations of jacks and terminals in this manual may be different from the ones actually used for your amplifier. The illustrations are of the most used type. First check whether your amplifier has a subwoofer output jack. It is usually named and printed as the SUBWOOFER OUT or SUBWOOFER. Before connecting this unit to the amplifier (or receiver), observe the following carefully. Before connecting this unit to an amplifier, turn off the amplifier first. Make all connections before plugging in this unit. DO NOT use the INPUT 1 (LOW-LEVEL) and INPUT 2 (HIGH-LEVEL) terminals on the rear of this unit at the same time; otherwise, noise will be heard and may damage the unit. DO NOT connect this unit to the REC OUT jacks of your amplifier.

SUBWOOFER OUT

Connecting to the Amplifier
When connecting to your amplifier (or receiver), refer also the manual supplied for your equipment.

Connecting Method

Connect an amplifier having a subwoofer output jack to the LEFT/MONO jack of the INPUT 1 (LOW-LEVEL) terminal. If you find it on your amplifier, follow Connecting Method. Preparation: Use the supplied monaural audio cord.

If you cannot find any

Next check whether your amplifier has line output jacks. They are usually named and printed as LINE OUT or LINE OUTPUT.

How to connect the speaker cords: 1 Press and hold the clamp of the speaker terminal. 2 Insert the end of the speaker cord into the terminal as illustrated below. Match the polarity of the speaker terminals: to and to. 3 Release the finger from the clamp.
If your amplifier has only a monaural line output (MONO) jack, connect it to the LEFT/MONO jack of the INPUT 1 (LOW-LEVEL) terminal (see Connecting Method ).
Connect an amplifier without a subwoofer output jack and line output jacks to the INPUT 2 (HIGH-LEVEL) terminal. When this method is used, connect your main (front) speakers to the TO MAIN SPEAKERS terminal on the rear of this unit. Preparation: Purchase speaker cords at an audio shop or electric shop.
When you connect main (front) speakers to the TO MAIN SPEAKERS terminal, use the speakers within the impedance range indicated by the amplifier connected to the INPUT 2 (HIGH-LEVEL) terminal. If not, the amplifier connected to the INPUT 2 (HIGH-LEVEL) terminal may malfunction and be damaged. DO NOT connect more than one speaker to one speaker terminal.

Operations

Turning On the PowerPOWER

Front view

Power lamp
Press the ON [ ] portion of the POWER switch. The main power turns on and the power lamp in the front panel lights in green. The power lamp lights in red when the AUTO POWER ON/ STANDBY places the unit into standby mode (see page 7).

Press in the CUT OFF FILTER button to set it to the _ FIX position.

VARIABLE FIX

The FREQUENCY knob is deactivated. When your amplifier is equipped with crossover frequency setting, set it within the range of 100 Hz to 150 Hz. When your amplifier is equipped with speaker size setting, select small.
NORMAL : Normally select this. REVERSE : Select this when you feel the bass sound is better with this mode rather than with NORMAL.
Operating the Unit Automatically According to the Incoming SignalsAUTO POWER ON/STANDBY
By using this function, this unit automatically enters standby mode even though the POWER switch is turned ON [ ].
If your amplifier is not provided with a crossover frequency setting:

1 Press out the CUT OFF FILTER button to set it to the
VARIABLE position. Now the FREQUENCY knob is activated and you can adjust the crossover frequency on this unit.
Press the AUTO POWER ON/STANDBY button to the ON position.

AUTO POWER ON / STANDBY

2 Turn the FREQUENCY knob to obtain the best matching
crossover frequency with your main speakers. Adjust the frequency (50 Hz to 200 Hz) while listening to playback sound coming out of both the main speakers and this unit.
If no sound comes in for about 10 minutes, the unit automatically enters standby mode. The power lamp lights in red. Then if the unit detects incoming signals, this unit starts operating automatically (the power lamp now lights in green). If Auto Power On/Standby does not work correctly (see MEMO below), press out the AUTO POWER ON/STANDBY button to set it to the _ CANCEL position. Auto Power On/ Standby is canceled.
If your main speakers can reproduce the bass sound well, adjust the frequency at a lower level. If you feel bass sounds are not sufficient, adjust the frequency at a higher level.
When the volume level of the amplifier is so low or the incoming signals are so weak that this unit cannot detect sounds, Auto Power On/Standby may not work correctly. This unit may enter standby mode even though signals are coming in. This unit may not start operating after entering standby mode, even though signals start coming in.

Additional Information

Speaker layout
To obtain the best possible sound from your unit: Place a subwoofer wherever you like since bass sound is nondirectional. Normally place it in front of you. Place all the main speakers at the same distance from the listening position.
