Delay

The delay parameter allows you to adjust the delay of individual channels by up to 70 msec. For example, this allows adjusting the driver’s side speakers audio to coincide with the arrival of the passenger side speaker at a listening point in the vehicle. Similarly, the audio arrival from the front and rear speakers can be adjusted. Using biamped connections and delay adjustment, this can help compensate for installations where the optimum tweeter mounting location will not accommodate woofer mounting and the effect of signal arrival differences can be minimized.

Use the following instructions to set the delay parameter for each speaker. The table printed below is provided for your use in facilitating the delay setup.

1.Set the delay of the farthest speaker from the desired listening position to zero.

2.Measure, in inches, and record the distance from the desired listening position to the farthest speaker. This is your baseline measurement.

3.Measure, in inches, and record the distance from the listening position to each of the remaining speakers. Each speaker should correspond to a channel of the output from the DCX-730.

4.Subtract the distance of the baseline speaker from each of the other speakers (for a given channel of the DCX-730) and record that value (these will all be negative values).

5.Divide each of these differences by 13.52 (value at 68°F) to set the required delay settings in msec for each of the remaining speakers. The exact speaker path length differences will appear for each channel as you enter the msec delay value.

NOTE: The value of 13.52 varies with temperature, a chart is given at the end of this discussion listing values to be used with different temperatures. The error in the this value is at the most 5% between temperatures of 50°F to 100°F.

For example: The baseline speaker (farthest away) measures 60 inches. The LT (left tweeter) measures 20 inches. The difference is 20-60=-40 inches. The delay time correction is -40/13.52 which equals a delay setting of -2.96 mS (a setting of 2.96 will be entered into the DCX-730 channel for the LT speaker.
