Denon AVP-A1HDCI Surround Sound Processor and POA-A1HDCI Power Amplifier - Page 3
A1HDCI amplifier that is designed to be
paired with the Denon SSP. The 12 outputs
are Front Left, Center, Front Right, Surround
A Left, Surround A Right, Surround B
Left, Surround B Right, Surround Back
Left, Surround Back Right, Subwoofer 1,
Subwoofer 2, Subwoofer 3. The Surround A
and B are if you want to have two sets of side
surround channels, such as in a very large
home theater room. The three subwoofers
can be configured for left, right, and LFE.
You can reconfigure any of the outputs to
be any of the other outputs (if you want to
duplicate an output channel).
The A1HDCI is organized around six input
sets (marked on the photo below). It is
assumed your sources are digital, perhaps
even all HDMI output, and the A1HDCI is
principally a digital audio processor.
So, looking at the photo, you can see the
HDMI inputs highlighted in red. They are
DVD, HDP, TV/CBL (this was changed
to SAT in the final release version), SAT
(changed to VCR in final release version),
DVR-1, and DVR-2 (you can change the
names to anything you prefer). To the right
of these inputs, highlighted in green, are
the HDMI output jacks for connection to a
projector and TV monitor. Below the HDMI
inputs are coaxial and optical digital inputs
associated with the HDMI inputs of the
same name. You can connect sources to any
or all of the inputs, and when you select one
particular input from the front panel, there is
an option to use any one of the sources you
have connected to the HDMI, or coaxial, or
optical jack associated with that input. In
other words, you can have a lot of sources
sharing each of the six main input sets. Each
HDMI input will have either a coaxial digital
or optical digital input associated with it, but
not both.
In the middle and down at the bottom are the
analog input sets assocated with each input.
They include component video, S-Video,
composite video, and stereo analog audio.
For CD, you can use either a set of fully
balanced XLR inputs or the usual RCA
inputs. You select whether you want XLR
or RCA from the on-screen menu setup
options.
“I must say that I have never had so
much enjoyment from a surround
sound system.”
Denon has a proprietary connection called
Denon Link. It is present on the A1HDCI,
as shown below. If you have a Denon player
with a Denon Link output, you can play
SACDs and send native DSD bitstreams to
the processor for decoding. The DSD remains
in that form all the way from the disc to the
processor decoding circuits , instead of being
converted to PCM like many other players
and processors do.
The A1HDCI has four zones. Zone 1 is the
principal one with the 12 output channels.
Zone 2 (marked in red) has component
video, S-Video, composite video, stereo
coaxial analog, and Toslink optical outputs.
Zone 3 (marked in green) has composite
video and stereo coaxial analog outputs.
Zone 4 just has Toslink optical output for
audio. So, basically, you could have audio/
video in three zones and audio in a fourth
zone, all playing at the same time in different
rooms of your home.
For my setup, I connected a Denon DVD-
2500BTCI Blu-ray player to the DVD input,
a Denon DVD-2930CI DVD player with
Denon Link to the HDP input, a DirecTV
satellite box to the SAT input, a Toshiba HD-
A1 HD DVD player to the VCR input, and
my media server to the DVR-1 input. All
of these are HDMI connections. My media
server has a DVI output, which I connected
to the DVR-1 HDMI input with an adaptor
cable for the video, and a Toslink optical
cable to the DVR-1 optical input jack just
underneath the DVR-1 HDMI jack. When
I selected that input, the SSP recognized
that video was coming in via HDMI and
audio via Toslink. This is one of the things
that most impressed me about the SSP. The
thing just worked, without any hassles trying
to decipher input configurations. The photo
below shows the media server connections.
I also have an old JVC VCR that I use to
play some instructional video tapes. I
connected this to the DVR-2 jacks, but used
the composite video and analog audio jacks
instead of the HDMI jack. This is shown in
the photo below.
So, all my sources are digital, connected via
HDMI (and Denon Link), except for the
JVC VCR which is analog.
I decided not to change the names of the
inputs as displayed on the front panel (because
they would then not match the names of the
jacks on the rear panel), but simply taped a
printout of the connections to the top of my
equipment rack which lists each input and
what is connected to it.
I used the SSP for several months with a Classé
CDP-502 five-channel power amplifier and a
two-channel amp for the sides, but recently
got the Denon POA-AH1DCI ten-channel
power amplifier and connected that to the
SSP. Here is a photo of the rear panel. (Click
on the photo to see a large version.)
The amplifier is modular, with all ten channels
arranged with their inputs and outputs across
the rear panel. At the top of each module are
RCA and XLR input jacks, and at the bottom
of the modules, you have to use a slider
switch to select which type of input you want
to use. The Denon SSP has XLR outputs,
so I used the XLR inputs on the amplifier
(Nordost cables). Also at the bottom you can
see switches to select whether the amplifier
module operates individually or bridged with
the adjacent module. If you select bridge or
bi-amp, the input to the right module of the
pair serves as input to two modules. For bi-
