Polarity, 1.5 HPF, 1.6 LPF | BBE DS48 specification

OPERATION

(The GAIN button will now select only the Output channels; the gain adjustment screens for the Inputs will not be displayed unless you use the BACK/NEXT but- tons or exit the menu and start again.) Each Output will have both a number and name displayed. The names are taken from a default list with labels such as Low, Mid, Highs, Sub, etc.

An alternate method is to program a single parameter for Output 1, such as DELAY, then press the GAIN button to go to each of the Output channels in turn and program the delay parameter for that channel. Now select the next param- eter and program that for each of the outputs in sequence. In some cases this may make it easier to keep track of the comparative values between outputs. For simplification, we will follow though programming all the parameters for a single output.

Set the Gain for Output 1. Range is –40 dB to + 6 dB

7.6.1.3Polarity:

Set the polarity for Output 1. Switching this will change the phase of the signal 180 degrees. If Outputs are linked, reversing the polarity of one of the linked channels will also reverse the polarity of the other linked channel.

7.6.1.4Delay:

Set the Delay time for Output 1. Delay is used to align drivers in a stack that may be in different vertical planes or multiple speaker in a stack. Delay range is 0ms to 7ms selectable in .1 ms increments. The delay is displayed in millisec- onds, meters and feet.

NOTE: Though there are some variables, generally speaking the speed of sound in 71 degree Fahrenheit dry air at sea level is ~773miles per hour. This is ~345 meters per second and about 1.13 feet per millisecond. .5 milliseconds equates to about 6.78 inches. .1 milliseconds equates to about 1.36”. The DS48 displays 1ms = 343mm = 1.1ft.

7.6.1.5HPF:

This is part of the crossover function. Sets the "knee" (corner frequency) and filter slope type for the HiPass Filter (HPF). Frequencies below the selected fre- quency will be filtered by the selected filter type and slope. Rotate the FREQ knob to select the frequency and the Q knob to select the filter type.

7.6.1.6LPF:

Set the "knee" (corner frequency) and filter slope type for the LoPass Filter (LPF). Frequencies above the selected frequency will be filtered by the selected
