CLASSE Omega Series Bedienungsanleitung Seite 4

BALANCED INPUT BAL 1, BAL 2, and BAL 3:
The XLR BALANCED INPUTS are true differential
high level inputs, wired as follows:
• PIN 1: GROUND
• PIN 2: POSITIVE (NON-INVERTED) SIGNAL
• PIN 3: NEGATIVE (INVERTED) SIGNAL
They may be used with CD players or DACs that
have a balanced analogue output, or any other
high level balanced analogue sources. We
recommend use of the XLR inputs whenever
a balanced output is available.
Tape In
The TAPE IN of the OMEGA SERIES PRE-
AMPLIFIER should be connected to the LINE OUT
or TAPE OUT of the tape deck. We have provided
an XLR Balanced connector as well as the RCA,
and we recommend use of the XLR input if your
tape deck or player has a balanced output. (See
FRONT PANEL CONTROLS: TAPE BUTTON.)
IR In (and Out)
The IR IN jack will permit you to install an
outboard infrared sensor and therefore be able
to control the OMEGA SERIES PRE-AMPLIFIER
remotely from another room where the outboard
IR sensor has been installed. These connections
will be found immediately above the DC power
inlet at the back of the pre-amplifier unit. The
IR output is the same as the IR signal input, and
the OMEGA SERIES PREAMPLIFIER may be daisy-
chained with other electronics which have similar
IR inputs (and outputs).
OUTPUTS
The Classé OMEGA SERIES PRE-AMPLIFIER has
two (2) LINE LEVEL (single-ended) and two
(2) balanced outputs. Both single ended and
balanced outputs are working at all times, and
may be used separately, or simultaneously.
Tape Output
Whatever input is selected by the INPUT
SELECTOR will be fed to the TAPE OUTPUT jacks.
This should be connected to the TAPE IN or LINE
IN of the tape deck. Only a LINE LEVEL, or RCA,
input is supplied.
Line Level Outputs
Simply connect your LINE LEVEL interconnects
to the RCA output jacks marked OUTPUT 1 or
OUTPUT 2 on the back of the OMEGA SERIES
PRE-AMPLIFIER and to the RCA inputs on your
amplifier(s).
Balanced Outputs
A power amplifier with balanced inputs and
balanced interconnects are also required. For
use with a balanced power amplifier other than
Classé, the wiring of the 3-pin XLR connectors
must be wired as follows:
• PIN 1: GROUND
• PIN 2: POSITIVE (NON-INVERTED) SIGNAL
• PIN 3: NEGATIVE (INVERTED) SIGNAL
If the pin configuration of the XLRs on the
power amplifier differs from above, the
balanced interconnects must be modified
to insure correct phase.
Having confirmed the correct connections, plug
the XLR connectors of the balanced interconnects
into the locking XLR connector on the rear of
the OMEGA SERIES PRE-AMPLIFIER marked
BALANCED OUTPUT. (To remove the connectors,
press the tab above the connector.)
Standby
The Classé OMEGA SERIES PRE-AMPLIFIER has
a STANDBY BUTTON located on the left lower
corner of the pre-amplifier front panel which
permits you to partially shut down the unit while
keeping important parts of the circuitry warmed
up.
Input Selector
The input selector has one button for selecting
the inputs. Pressing the button cycles through
the six available inputs: LINE 1, LINE 2, LINE 3,
BAL 1, BAL 2, and BAL 3, then back to LINE 1.
Tape
(TAPE input selection is available from the remote
wand only.)
Volume Control
The VOLUME CONTROL varies the output level of
both channels simultaneously. It can be operated
manually by rotating the wheel to the right to
increase or to the left to decrease the volume,
or remotely using the hand held control unit.
The volume control has a total of 120 steps of
level adjustments from 0 to 60 in 0.5 stepped
increments. When the unit is taken out of
standby mode, the volume will be automatically
at zero (0) and the preamp will be muted.
("MUTE" read-out in display). Adjusting the
volume wheel to the right will un-mute the pre-
amplifier and the selected source may be heard.
PLEASE NOTE: It is normal for the volume to
stay at the same level if you turn the VOLUME
knob extremely slowly.
Mute
Press the MUTE button to temporarily mute
the VOLUME to 0. When activating the MUTE
function "MUTE" will readout in the display.
Switching mute on and off can be done by either
pushing the MUTE button momentarily on the
OMEGA SERIES PRE-AMPLIFIER faceplate or on
the remote handset. The volume setting will
remain the same when the unit is in mute mode;
thus Volume will return to the same level it was
playing at prior to muting when you turned off
MUTE mode.
PLEASE NOTE: The display will change to Display
Full Off mode after the unit has been in MUTE
mode for an hour.
PLEASE NOTE: When the OMEGA SERIES PRE-
AMPLIFIER is in mute mode, and the volume
control is turned up using the volume control on
the remote or the unit, the play mode will be
automatically selected.
CAUTION: When changing any input or outputs
the pre-amplifier must be turned off and
unplugged from AC. All the associated
amplifier(s) and other electronics must be
turned off.
Remote Handset
The remote handset will permit you to access
remotely all the functions found on the front
panel of the unit: VOLUME UP or DOWN,
BALANCE LEFT or RIGHT, MUTE ON or OFF,
DIRECT ACCESS for all the INPUTS and TAPE
monitors. In addition to all these functions, the
button marked DISP will permit you to select
through the four Display modes on the unit.
PLEASE NOTE that the DISPLAY function can
only be accessed with the remote handset.
To access the batteries, unscrew the back plate of
the remote handset.
AMP: (on remote handset only)
The AMP button may be used to turn the
OMEGA SERIES AMPLIFIER(s) ON and OFF.
Standby
Pressing the STANDBY BUTTON on the remote
handset permits you to partially shut down
the unit while keeping important parts of the
circuitry warmed up.
BAL1 – LINE 3: (on remote handset only)
Pressing each of these six buttons directly
accesses the associated input on the
pre-amplifier.
Display: (on remote handset only)
Pressing the DISP button on the remote
handset allows you to control the brightness
of the display. There are 4 levels of brightness:
Display Full On, Display Medium On, Display
Low On or Display.
Full Off. Repeated pressing of the DISP button
will cycle through the four modes, from Display
Full On to Display Full Off. Pressing DISP when
the display is at Full Off will cause the display to
go back to Display Full On.
PLEASE NOTE: Four (4) LEDs will continue to be
lit on the display when it is in Display Full Off
mode to let you know that the OMEGA SERIES
PRE-AMPLIFIER is still on and operating. When in
Display Full Off mode and any other functions
are used, such as changing volume or selecting
a new source, the display will light at Display Full
On mode for five seconds and then go back to
Display Full Off mode. The display also will
automatically go to Display Full Off mode after
the MUTE mode has been activated for an hour.
Tape: (on remote handset only)
Pressing the TAPE button on the remote handset
first selects TAPE 1 (RCA input), next the (XLR
balanced) TAPE 2 input, then next TAPE OFF.
Pressing the TAPE button again cycles back to
the TAPE 1 inputs, and etc.
