Frequently Asked Questions - SUB8 Kanto

How do I connect the SUB8 to my receiver?

Use the LINE IN (LFE) RCA input for a subwoofer pre-out, or connect speaker wire to the SPEAKER LEVEL inputs via 5-way binding posts.

What crossover setting should I use?

Set the low-pass filter dial to match your main speakers' lower limit (typically 80 Hz) or use the receiver's bass management.

Why is the subwoofer not turning on?

Check the power cord connection, ensure the power switch is on, and the audio signal is present. The auto-on feature activates after a few seconds.

Can I place the subwoofer in a cabinet?

Avoid enclosed spaces to prevent overheating and muffled sound. Leave at least 4 inches (10 cm) clearance around the port.

What is the difference between 0° and 180° phase?

Phase control aligns the subwoofer's output with your main speakers. 0° is typical; switch to 180° if bass sounds weak or boomy.

How do I clean the subwoofer?

Use a soft, dry cloth to dust the enclosure. Do not use liquids or abrasive cleaners.

Does the SUB8 have a subsonic filter?

No dedicated subsonic filter; the low-pass filter covers the operating range. Avoid very low signals near port tuning frequency.

What is the warranty period?

Kanto offers a 2-year warranty from the date of purchase. Register online for extended coverage.

Can I connect two SUB8 subwoofers?

Yes, if your receiver has dual subwoofer outputs. Use a Y-splitter if needed.

The LED indicator is not lighting up. What's wrong?

Ensure the subwoofer is receiving power and an audio signal. If still off, check the fuse (internal) or contact support.

Introduction

Thank you for choosing the sub8 powered subwoofer. sub8 was designed to augment the bass performance of your speakers in a stereo setup or in a home theater installation.

Adding a subwoofer to your system extends the bass response produced by your existing speakers and improves their midrange clarity. In a home theater application, the subwoofer takes care of reproducing signals from the low frequency effects channel. In a stereo system, the subwoofer helps reduce the low-frequency demands on the main speakers.

We recommend you read all instructions carefully before using the sub8 and keep them for future reference. Kanto cannot be liable for damage or injury caused by incorrect setup or use of this product.

This powered subwoofer was carefully tested and inspected during production, and before packaging and shipping. After unpacking, please check for any damage. It is rare that a unit is damaged during shipping, but if this happens contact your retailer immediately. You can also contact Kanto directly:

Setting up and Connecting your Subwoofer

Ensure that the ON/OFF Switch is in the OFF position before connecting any component.

To some degree, positioning the subwoofer is less critical because it produces only non-directional low-frequency sounds. However, best results are obtained if the subwoofer is placed either between the left and right speakers or in the vicinity of either the left channel or right channel speaker.

As with all speakers, moving the sub8 very close to room boundaries will enhance the bass frequencies but will tend to muddy the sound. Room characteristics and positioning have a profound effect on the performance of the subwoofer, so time and effort devoted to achieving the optimum operating position will be rewarded.

In a typical full range application using one subwoofer like the sub8 thru a single wire connection, you can connect to either the Left or Right Line Level Input. Connect your stereo component such as powered speakers with subwoofer output (e.g. YU2, YU4, YU6), power or integrated amplifiers with preamplifier output, or multi-channel home theater receivers with subwoofer output. If your components are equipped with both L/R subwoofer outputs or L/R preamplifier outputs, we recommend connecting the component to the sub8 by using both Left and Right Line Level Input channels.

The Low-Pass Filter Control is used to set the upper limit of the frequencies that sub8 will reproduce, typically within the range of 40Hz-120Hz. Refer to your manufacturer's information for the cut-off frequency of your main speakers.

The Phase Switch is normally set to 0^ . If the sub8 is positioned significantly farther from the main speakers or if the subwoofer is used in a stereo setup where the amplifier driving the main speakers inverts the phase signal, the 180^ setting may be desirable. Listen with the switch in both positions and select the setting that gives the fullest sound. If in doubt, or if there is little difference, leave the switch set to 0^ .

Follow the instructions on the following page to connect your components to sub8. The examples are not meant to be exhaustive - just examples.

ATTENTION

When connecting audio cables the ON/OFF Switch must be turned OFF. After connecting all cables, the unit can be turned ON.
