Setting The Channel Delays - Bryston SP 1 Series Instructions Manual

to effectively handle the low frequency dynamics of modern
motion picture soundtrack sources such as DVD or HDTV
feeds, and many other discrete multi-channel programming
sources. If in any doubt choose small, especially if you are
using a subwoofer, since this will insure that all the
appropriate low frequency information is directed to the
subwoofer where it can be most effectively handled.

Setting the Channel Delays

In this step you will need to measure within one foot the
distances from your chosen listening/viewing position to the
various loudspeaker locations in your system.
You will need the tape measure or other means of making
these measurements.You should record this data for future
reference.
1. Now, make a measurement from the chosen seated position
to each loudspeaker.
2. Next, enter the main menu by pressing on one of the menu
buttons on the SP1 front panel. Move the cursor to "DLY".
Hit 'Select' - You are now in the Delay Menu.
The SP1 automatically calculates the required delay time per
speaker using the data entered as distance from the
listening position. Delays are implemented using DSP RAM
and have a maximum value.
IMPORTANT: It is recommended that the closest speaker is entered first.
The SP1 will calculate the maximum allowable distance from the listening
position for the remaining speakers. Please note that delay is
represented in feet. For reference, One foot (0.3048 meters) =
approximately 1 millisecond of delay.
3. Move the cursor to the speaker you want to set the
distance/delay for (L C R LS RS SB). Hit Select. Now you
can adjust the Delay value which is equivalent to the
distance you measured for the selected speaker using the
arrow buttons. Set the delay for each speaker in your system
to the nearest foot/meter. Rounding up is OK.
4. Hit SELECT or [X]Exit when finished.
The SP1's default factory settings as shipped are 10 feet to
every speaker, resulting in zero overall delay.
