Your subwoofer is a high value product using the latest materials, technology, and equipment by DCM, a vertically integrated company.

Thank you for selecting DCM in making your audio equipment purchase.

INTRODUCTION

Your new subwoofer has many features which help to deliver great bass performance and make it a remarkable value.

* High efficiency amplifier:

The DCM1010, DCM1212 (class A/B) and DCM1515 (class D) represent the latest amplifier technology with active compression circuits for higher SPL without breakup during high amplitude peaks.

* Versatile hook-up and operation:

Your new subwoofer has a variety of input and output connections that make it easy to set-up and use in almost any stereo or home theatre system.

* Low distortion woofers:

Each woofer uses an overhung voice coil and large excursion suspension to produce higher sound pressure levels with lower distortion.

* Optimal enclosures:

Each enclosure is designed to match the parameters of its woofer to maximize performance. Passive radiators are used for less distortion at the bottom of the frequency range.

SET-UP AND ADJUSTMENT

After you have selected an initial location for your subwoofer and have connected it into your system, have a seat in your normal listening position and have someone help you with the following adjustments:

A)If you are using the line level inputs and your main speakers are receiving a full range signal, set the subwoofer crossover frequency control to its full counterclockwise position.

B)Set the polarity switch to the “normal” position and the level control to the full counterclockwise position at “minimum”.

C)Turn off the loudness control and set the bass tone control on your main amplifier to the flat position.

D)Use familiar program material that has substantial bass content and play your main system at a moderate volume level.

E)Slowly rotate the subwoofer level control clockwise until a good balance is achieved between the low frequency output of your subwoofer and the mid bass and upper frequencies from your main speakers.

F)Slowly rotate the subwoofer crossover frequency control clockwise to attain the best blend between the level of the subwoofer and the main speakers in the midbass crossover region. Advancing the control too far will cause a “boominess” in the overall sound and will add an unnatural “chesty” quality to male voices.

G)Change the polarity switch from “normal” to “reverse” to determine which position results in the most overall bass output. Leave the switch in the position that gives the highest output level.
