REAR-PANEL INPUTS
Be certain that the Stage One preamp/processor, your amplifiers, and all
other associated components are powered OFF before making or break-
ing any connections to the preamplifier. Failure to do so may result in
damage to your speakers or other equipment.
1
ANALOG INPUTS
Seven stereo analog inputs are provided on the rear panel. The analog
inputs are labeled for convenience only, as any line-level source can be
plugged into any analog input. (See "Analog Input Level Control.")
2
DIGITAL INPUTS
Ten digital inputs are provided on the rear panel: seven Coaxial and three
Toslink optical. They can accept digital output from any device that delivers
a standard S/PDIF signal. On the TV, DVD, and CD/LD inputs, the Toslink
input takes precedence over the Coaxial input. Both may be connected
simultaneously.
3
COMPOSITE VIDEO INPUTS
Seven composite video inputs are provided on the rear panel. When an
A/V source is selected, the corresponding video input is also selected and
routed to the Monitor and Record outputs. Video inputs can also be select-
ed independently of the audio inputs. (See "Selecting a Separate Video
Source.")
4
S-VIDEO INPUTS
Seven S-video inputs are provided on the rear panel. When an A/V source
is selected, the corresponding video input is also selected and routed to
the Monitor and Record outputs. Video inputs can also be selected inde-
pendently from audio inputs. (See “Selecting a Separate Video Source.”)
5
COMPONENT VIDEO INPUTS
Three Component Video inputs are provided on the rear panel. These are
assigned to the TV, DVD and Video inputs and are high-definition compati-
ble. When one of these three sources is selected, the corresponding com-
ponent video input is also selected and routed to the Component Video
output. Video inputs can also be selected independently from audio inputs.
(See “Selecting a Separate Video Source.”)
6
RS-232 IN/OUT
The RS-232 port enables the Stage One to communicate with
external control devices or to connect with expansion boxes for future
upgradability. This port also allows for software upgrades to be installed
to the Stage One.
7
IR INPUT
The external IR input on the rear panel allows for an electrical connection
to an infrared receiver module.
8
MULTI-CHANNEL ANALOG INPUT
A DB-25 connector is provided on the rear panel to allow a six- or
eight-channel analog input from a DVD, DVD-Audio, or SACD player.
Compatible RCA to DB-25 adapters are readily available from many
manufacturers. (See “Input Connections.”) This input bypasses the DSP
module.
9
EXPANSION PORT
This port provides for expansion capability for future use should current
or future formats require a method of connection not currently supplied
on the Stage One.
10
AC INPUT
AC Power is supplied to the Stage One via a standard IEC three-wire
power cord.
11
FM ANTENNA INPUT
A 75-ohm F-connector input is provided on the rear panel to attach to an
external FM antenna.
12
AM ANTENNA INPUT
Spring clips are provided on the rear panel to connect an external AM
loop antenna.
