Installation Manual

Output Conguration

1. Mono: This allows you to sum any stereo pair down to mono. This

feature, in combination with the Input View polarity controls, are

very useful for checking input polarity and time alignment by

applying the knowledge that two signals time-aligned and of in-

verse polarity, will cancel each other out when summed to mono.

2. 180 Deg: Invert the polarity of the output selected. Blue is 180

deg, black is 0 deg. Changing this control is much easier than

getting back in the trunk and rewiring the amplier outputs.

3. Link: This control is intended to speed up the tuning of multi-way

systems by linking two outputs so that their SUMMING, EQ, Delay

and Level are adjusted in tandem. The crossover Low-Pass setting

of the lower numbered output pair is linked with the High-Pass

setting of the higher numbered pair. A popular setting for this

is outputs 1-2 = Front Woofers and outputs 3-4 = Front Tweeters.

After adjusting in Link, you can unlink the outputs if, for example,

you want to set the tweeter delays independent of the woofer

delays, or if you wish to ne tune the crossover settings between

the woofers and tweeters.

Delay / Distance

1. These delay controls are for independent delay of any output

signal. This allows for sweet spot adjustments left/right, as well as

front/back sound stage presentation and woofer/tweeter arrival

time alignment.

a. In DISTANCE mode (inches or metric), set the distances

exactly as you measure them from the speakers to the

sweet spot (usually the driver’s headrest or center of the

listening area). The DM Smart DSP application will use

these distances to calculate the correct delay osets for

simultaneous arrival of all signals.

b. In DELAY mode (milliseconds) you can directly enter the

delay times in milliseconds.

NOTE: the DELAY / DISTANCE settings are stored by preset, so

you can easily compare multiple versions of the same set-

up with minor tweaks, or set dierent proles for dierent

passenger congurations.
