ANALOG OUTPUT
(Slot 2)
1. BALANCED LINE OUTPUT
Connections to an amplifier or preamplifier that uses balanced XLR input connectors,
such as ADVANTAGE S100 or S2 or directly to your S150 or S250 power
amplifiers.
Balanced signal transmission provides far better suppression of outside electrical
interference and shielding.
The wiring standard used for these connectors is:
Pin 1:Chassis Earth (GROUND)
Pin 2:Hot (+ OUT)
Pin 3:Signal Ground (- OUT)
2. UNBALANCED LINE OUTPUT
Connect an RCA cable from these jacks to your amplifier. Plug one end of a stereo audio
cable into the Left (upper) and Right (lower) output jacks. Connect the other end of the
cable to your stereo amplifier's CD input, or to any other "line-level" input jacks (such as
the AUXiliary inputs). Do NOT connect this cable to any amplifier's PHONO input jacks.
Make sure that the plugs are pushed home properly.
THE BENEFITS OF BALANCED CONNECTIONS
With a conventional (unbalanced) connection, audio signal current flows from the CD
player to the amplifier via the cable's centre conductor. To complete the circuit, audio
signal current flows back to the CD player ground via the cable's outer conductor. The
outer conductor also serves as the cable's shield.
When two audio components are connected together, power-supply noise and "leakage"
hum may also flow on the cable shields, combining with the return audio current. The
resulting distortion and noise may depend on the orientation of AC power plugs in their
sockets. Designers of some audiophile cables combat this contamination by leaving the
shield unconnected at one end. Since the shield is grounded at only one end, the
performance of such a cable may depend on the direction of its connection, i.e. whether
the shield is grounded at the CD player or at the amplifier.
A three-wire balanced connection avoids all of these uncertainties. The signal "hot" and
return currents are both carried on inner conductors. The separate cable shield,
connected to the amplifier chassis at both ends, protects the audio signal from all forms
of interference and power-supply noise.
Slot 3 and 4 are nor used in this configuration
DATA COM and RS232 connections
The Data Com connection is used to exchange information between different Advantage
products.
The RS232 port is used to control or program the unit from an external controller or
computer
MAIN POWER SWITCH
Press this switch to switch on the power to the player. Switch the unit off only if it is not
going to be used for a longer period.
IEC AC MAINS (POWER) INPUT
The S1 comes supplied with a separate AC Mains cable. Before connecting the cable to
a live wall socket ensure that it is firmly connected to the ADVANTAGE S1's AC Mains
input socket first. Always disconnect the AC Mains cable plug from the live wall socket
first, before disconnecting the cable from the S1 Mains input socket.
