Frequently Asked Questions - Signature Elite Subwoofer ES8 DENON

How to connect the subwoofer to an AV receiver?

For an AV receiver with LFE output, use an RCA cable from the receiver's LFE output to the subwoofer's LFE input. The subwoofer automatically detects the LFE connection and bypasses the low-pass filter. If your receiver does not have an LFE output, use the left and right line inputs with a standard RCA cable.

Where to place the subwoofer for best performance?

Place the subwoofer on the same side as the front speakers in the room. Placing it near a wall or in a corner increases sound level. Avoid placing it near an open door. Try different locations to find the best sound quality.

How to adjust the volume and low-pass filter?

Use the +/- buttons on the rear panel. Start with volume at 50% and low-pass at 80 Hz. Adjust by ear to achieve deep bass without a 'boomy' effect. If using an AV receiver, let room correction (Audyssey, Dirac) optimize the settings.

What do the LED indicators on the rear panel mean?

The orange light indicates that the subwoofer is in standby. The green light indicates it is on and ready. The lights on the light bar indicate volume, low-pass frequency, and phase adjustment.

How to clean the subwoofer?

Dust regularly with a dry cloth. Never use abrasive or solvent-based cleaners, or harsh detergents.

The subwoofer does not turn on, what should I do?

Check that the power cable is properly connected to the subwoofer and to the wall outlet. Make sure the main power switch is in the ON position. If the subwoofer is in auto mode, wait for an audio signal to be present.

What is the warranty on the subwoofer?

Limited warranty of 3 years for electronics and amplifier, and 5 years for subwoofer and speaker, in North America. For more details, see the manual.

Can I connect the subwoofer to a stereo system without LFE output?

Yes, use the left and right line inputs (RCA). Connect them to the left and right pre-outs of your amplifier. Then adjust the volume, low-pass, and phase on the subwoofer.

How to adjust the phase on the subwoofer?

Use the +/- buttons next to the phase control. The default setting is 0 degrees. If using a single subwoofer, leave at 0°; otherwise, adjust in 45° increments for better integration with the speakers.

Where to find replacement parts or technical support?

For any assistance or replacement parts, contact an authorized dealer or visit support.polkaudio.com.

Position the subwoofer

Your subwoofer offers many placement options: in an entertainment center, behind furniture, or next to a sofa or chair.

You may place your subwoofer anywhere in the room, but you'll enjoy the best performance when it's on the same side of the room as your system's front speakers. See the image to the right for potential placement options.

Placing your subwoofer near a wall or in a corner will increase its loudness. When placing your subwoofer in the room, always place your subwoofer on its base feet side down. If you can at all avoid it, do not place your subwoofer next to an open door.

We recommend placing your subwoofer in different locations within your room to learn what produces the best sound quality for your listening environment.

Connect the subwoofer to your AV receiver or amplifier

LFE setup

LFE (low-frequency effects) is recommended for AV receivers with a dedicated LFE channel or subwoofer pre-out.

1. Turn off the power on your amplifier/receiver.
2. Connect the LFE cable from your receiver to the dedicated LFE input.
3. The subwoofer detects when an LFE cable has been connected and automatically sets to LFE mode and bypasses the low-pass filter.
4. Follow the bass management instructions on your AV receiver to integrate the subwoofer into the rest of your audio system.

Line in setup

This method is recommended for systems with no LFE/subwoofer output jack, such as 2-channel systems.

1. Turn off the power of the device (such as a pre-amplifier) you intend to connect to the subwoofer.

2. Connect standard RCA cables from the left and right inputs of the subwoofer to the appropriate output of the device, usually a left and right post-volume pre-out.

NOTE: Do not use a tape-out or record-out as these will not track the volume control.

1. Adjust the volume, lowpass, and phase controls on the subwoofer as needed. You can start at 80Hz and 0 degrees and adjust from there.

4 Plug in the power cable and turn on the subwoofer

1. Plug the power cable into the subwoofer, then into a power outlet.

2. Turn on the subwoofer by switching the Main On/Off Switch. See the next page for more information.

Subwoofer features

Subwoofer back-panel controls

1 Volume control	When you set up your subwoofer for the first time, you may have to make adjustments several times before you hear what you personally like. Start with the volume at 50%. Adjust by ear using a wide variety of CDs and video sources. Adjust for deep, powerful bass without "boominess."We recommend that you use your AV receiver to run room correction features (like Audyssey or Dirac) and allow the receiver to optimize your speakers and subwoofer(s).
2 LED power indicator	Amber: The subwoofer is connected to power and in standby mode.Green: The subwoofer is on and ready to use.
3 Phase control	Tap the +/- buttons next to Phase to adjust the phase setting. If you're using a single subwoofer, you can generally leave the phase at 0 degrees. However, you may need to change the phase depending on your speaker arrangement.
4 Auto on / Always on switch	Auto On: Subwoofer wakes up as soon as it receives an audio signal and goes into standby ~20 minutes after the audio signal is stopped.Always On: Subwoofer never enters Standby. Use this mode if you have a means of controlling the main AC power to the subwoofer.
5 Low-pass control	If your AV equipment doesn't have its own low-pass filter, you can adjust the low-pass filter higher or lower as preferred. If you connect an LFE cable from your AV receiver to the subwoofer, the subwoofer automatically switches to LFE mode. With the subwoofer in LFE mode, configure crossover settings in you AV receiver.
6 LFE Input	LFE (low-frequency effects) is recommended for AV receivers with a dedicated LFE channel or subwoofer pre-out. See the previous page for connection instructions.
7 Line Inputs	This method is recommended for systems with no LFE/subwoofer output jack, such as 2-channel systems. See the previous page for connection instructions.
8 Main On/Off Switch	Use to completely cut the power to the subwoofer. Similar to removing the power cord.
9 AC power inlet	Used to provide power to the subwoofer with the included power cable.

Subwoofer adjustments & status lights

The Signature Elite Subwoofers include LED status lights to indicate the volume level, low-pass frequency, and phase setting. You can control these levels by pressing the corresponding + or - button on the back panel.

NOTE: The default subwoofer volume is 20, the default low-pass frequency is 80Hz, and the default phase setting is 0 degrees.

Volume levels

The subwoofer volume can be set between 1 and 40. Each LED light can shine at four different brightness levels to indicate the volume. See below for an example of some of the volume levels.

Low-pass frequency

The low-pass frequency levels are labeled above the LED light strip. When one LED is dim, you're half way to the next frequency level. In the example below, the dim LED means 85Hz, half way between 80Hz and 90Hz.

Phase setting

A single LED will light up to show where the phase is set. The phase levels are labeled on the back panel of the subwoofer, below the LED light strip. In the example below, phase is set to 0 degrees and 45 degrees.
