Enabling any of the Noise generators sets
Decoder_Src to zero, thus the previous source needs
to be manually re-selected after noise generation is
complete.
Selecting any of the analog audio inputs (CAT5
through Audio In #6) will also affect the DAP8 Stereo
Audio Switch setting on slot 06.
High_Dyn_Range,
Low_Dyn_Range
High_Dyn_Range_Fb,
Low_Dyn_Range_FB
I
O
Controls dynamic range compression in Dolby Digital
sources. The control range is 0 to 100% (for
minimum to maximum compression).
For most applications, these signals need not be
used, since the DYN_Range inputs described before
offer adequate control of compression ratios.
Sub_Limit
Sub_Limit_FB
I
O
Sets the peak limit, or maximum output level of the
subwoofer. The peak level is adjustable within a
range of –25 dB to 0 dB. Values more negative than
-24.0 dB disable peak limiting (the default setting).
LFE_Trim
LFE_Trim_FB
I
O
Sets the amount of gain to the LFE, or Low
Frequency Effects channel during bass management.
The LFE trim is adjustable within a range of –15 dB
to 0 dB.
Trim_L through
Trim_Sub
Trim_L_FB through
Trim_Sub_FB
I
O
Sets the gain of the indicated channel. The trim is
adjustable within a range of –30 dB to +30 dB,
although Dolby recommends a range of –12 dB to
+12 dB. The Master Volume and the trim volume
(and possibly other compensation terms) are added
together to produce the output volume.
Delay_Left through
Delay_Sub
Delay_Left_FB through
Delay_Sub_FB
I
O
Sets the delay, in milliseconds, for the indicated
channel. The delay is adjustable within a range of 0
ms to 20 ms, although the Dolby recommendations
are 0 ms to 5 ms for the center channel and 0 ms to
15 ms for all other channels.
Certain Pro Logic decoding modes add a 10 ms
delay that is not displayed or accounted for here.
Global_Bass,
Global_Treble
Global_Bass_FB,
Global_Treble_FB
I
O
Sets the bass and treble settings for all digital output
channels. The bass and treble are adjustable within a
range of -18.0 dB to +18.0 dB.
