DCP includes HI – Select to route DCP HI In on pin 7 to the AP20 RCA jack. If
disabled, HI Out is mixed from DCP In L, R, C.
DCP includes VI – Select to route DCP VI-N on pin 8 to AP20 channel 16. This channel
becomes a fixed level, not affected by the fader value. Channel 15 becomes unavailable.
ES Matrix – Select to play in an Extended Surround (ES) 5.1 configuration. Matrixed surround
format is a digital soundtrack format used in film and not a standard DCP format. The
surround channels from inputs 5 and 6 are matrix decoded to create a center back surround
channel that is routed to the back surround channels, or AP20 channels 7 and 8. The undefined
channels 9-16 are mapped directly to the AP20 channels 9-16.
Matrix – Select to expand 2-channel mix to 5 channels or 5.1. Digital In channels 1 (L) and 2
(R) are sent through a matrix and output to AP20 channels Out 1-6 (L, R, C, Lfe, LS, RS) and
HI Out is mixed from DCP In L, R, C. The undefined channels 9-16 are mapped directly to the
AP20 channels 9-16..
Enable Bass Enhancement – Select to add bass enhancement is added to the matrix in
which the low frequencies are routed to AP20 channel 4.
4.3.6.6 Decoder Setup
This screen is available for the following input sources:
Digital ch 1,2
Digital ch 9,10
TosLink A or B
S/PDIF Coax
HDMI 1-4
The AP20 accepts a DTS, DTS-HD, DTS-HDMA or Dolby® Digital audio stream from a DVD, Game
Console, Satellite link or other source device. The Encoded bit stream is automatically detected and
decoded internally by the AP20 software. The decoded stream is routed to the first eight channels
internally on the AP20.
The following digital inputs accept DTS or Dolby
HDMI (ports 1 – 4 )
S/PDIF1 (TosLink A)
S/PDIF2 (TosLink B)
S/PDIF3 (Coax)
Operation
The AP20 monitors the selected input signal from one of the S/PDIF or HDMI ports to determine the
type of audio signal received. If a DTS, DTS-HD or Dolby Digital bitstream is detected, the AP20
decodes the audio and places it on the first 8 channels (see Table 1).
If an un-encoded digital signal is received (i.e. 2-channel PCM), the signal is routed to the first two
channels in the AP20 (Left and Right) and the others remain muted. The HDMI also supports 6 or 8
channel un-encoded PCM signal. The AP20 will switch between stream types as the signal type changes.
This occurs automatically within the AP20.
