Setting Up the DMA8Plus
3.6.2 Surround Delay
When the unit receives audio from a digital media source, you need to apply a delay to the
Surround channels, so the Center and Surrounds audio reach the listener at the same time.
Set the Surround Delay by entering the dimensions of the auditorium and clicking the
Calculate button, or use the slider if you know the required delay setting.
Note:
If the DMA8Plus is connected to a CP650, the CP650 applies the appropriate digital
media surround delay based on its settings (format 11). If the CP650 has been
selected as the cinema processor type, the Surround Delay setting in this window is
disabled. Use this function to set the digital media surround delay only when
connected to other cinema processors.
3.6.3 Pro Logic/Pro Logic II Subwoofer
Selects a subwoofer filter of 50 Hz (default) or 100 Hz for Pro Logic and Pro Logic II
decoding. This subwoofer signal is derived from the matrix decoded sum of Left, Center,
and Right, which passes through this filter. The main audio outputs bandwidth (L, C, R) is
not affected because this subwoofer signal is a reinforcement rather than a bass redirection.
3.6.4 Power-on Mode
Selects the desired DMA8Plus startup mode when the unit is powered on. You can select
Last Setting, Film, or any of the digital inputs: digital 1 (4xAES), digital 2 (1xAES),
digital 3 (1xAES), or digital 4 (Optical).
