Frequently Asked Questions - SA-W55X SONY

How do I connect the SA-W55X to my receiver?

Use an RCA cable from the subwoofer output of your receiver to the LINE INPUT on the subwoofer. Alternatively, connect speaker level wires from the receiver's speaker terminals to the SPEAKER INPUT terminals on the subwoofer.

What is the crossover frequency setting?

The crossover frequency knob adjusts the upper limit of the subwoofer's output. Set it to match your main speakers' low-frequency capability (typically 80-120 Hz for home theater).

Why does my subwoofer have no sound?

Check that the subwoofer is powered on, the volume is turned up, and the input cables are securely connected. Also verify that the receiver's subwoofer output is enabled.

What does the phase switch do?

The phase switch (0° or 180°) inverts the polarity of the subwoofer signal. Choose the setting that gives the most bass at your listening position, typically 0° for subwoofers placed near the front speakers.

Can I use the SA-W55X with a stereo system?

Yes, it can be used with any audio system that has a subwoofer output or speaker level outputs. For stereo use, connect via speaker level inputs.

What is the auto standby feature?

The subwoofer automatically enters standby mode after a period of no audio signal to save power. It reactivates when a signal is detected.

How should I position the subwoofer?

Place the subwoofer on a solid, level floor, preferably in a corner or near a wall for enhanced bass. Avoid blocking the bass reflex port on the front or rear.

Does the SA-W55X have a built-in amplifier?

Yes, it is an active subwoofer with a built-in amplifier, so no external amplifier is needed.

What is the power consumption in standby?

Standby power consumption is typically less than 0.5 W, complying with energy-saving standards.

How do I clean the subwoofer?

Unplug the subwoofer and wipe the cabinet with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.

Connections

Notes on Connection

• The power cord should be connected last of all, after making sure that the POWER switch is turned off.
• The cable connectors should be fully inserted into the jacks. Loose connection may cause hum and noise.

- The + and - cords of the connection adaptor should be correctly connected to the + and - terminals of the amplifier respectively to avoid damaging to each units.

When Connecting the Amplifier Having a Super Woofer Output Terminal with the Audio Cord

When Connecting to the Speaker Terminals of the Amplifier with the Connection Adaptor

Location and Function of Controls

1 POWER button and indicator

When the button is pressed, the indicator lights up, and the unit is set in power stand-by mode – the internal power amplifier is automatically turned on when receiving any input signals. When not receiving input signal during a few minutes, the amplifier is automatically turned off. Depress the POWER button again when the unit is not used.

② TURNOVER frequency selector

Select the turnover frequency among 60 Hz, 90 Hz, and 120 Hz so that the highest frequency of the unit may smoothly contact with the lowest frequency of the front speaker system.

When the front speaker system has a large size woofer, set the selector to 60 Hz. When the front speaker system has a medium size woofer, set the selector to 90 Hz. When the front speaker system has a small size woofer, set the selector to 120 Hz.

③ PHASE selector

Set the phase to NORMAL or REVERSE according to the phase of the front speakers.

4 BOOST button

To boost the bass sound, depress the button.

5 VOLUME control

Adjust the control to balance the volume of this unit with that of the front speaker system.

To increase the volume, turn the control clockwise. To decrease the volume, turn the control counterclockwise.

To prevent possible damage caused by the magnets

Keep personal credit cards, watches, recorded tapes away from the unit.

In case color irregularity is observed on nearby TV screen

With the anti-magnetism design of the unit, the speakers can be installed near a TV set. However, color irregularity may still be observed on the TV screen depending on the type of your TV set.

If color irregularity is observed...

Turn off the TV set once, then turn it on after 15 to 30 minutes.

If color irregularity is observed again...

Place the unit more apart from the TV set.
