1. OPERATION SWITCH / Power Stand-by / On, push button turns the C-1000f either ON
or OFF (stand-by).
2. OPERATION INDICATOR; LED blinks gently initially to show that it is warming up, will shine
constantly once the C-600f is fully operational. The legend Warming Up will be displayed
meanwhile.
3. NPUT SELECTOR; select any one of the eight music signal sources, either from this knob on the
front panel or from the remote control
4. STAND-BY INDICATOR, glows yellow while in stand-by.
5. OPERATION DISPLAY; the illuminated display makes it easy to view the selected music source
& the volume setting, even from a distance.
6. VOLUME CONTROL; adjust the Volume Control for the desired listening level. The VOLUME
control adjusts the overall loudness of the signals being fed to the loudspeakers. It is fully
electronic and can also be adjusted from the remote control handset. The VOLUME control does
not affect recordings made using the Tape outputs.

may not work.
NOTE: Direct sunlight or very bright ambient lighting may affect the operating range and angle for the
remote control handset.

13. UNBALANCED OUTPUTS need to be connected to an outboard amplifier(s).
14. UNBALANCED INPUTS, Line 1 –3 These inputs accept the stereo output signal from CD,
SACD, DVD-Audio, Tuner (XM, Sirius).
15. BALANCED INPUTS 1 –2. These inputs accept the stereo output signal from CD, SACD,
DVD-Audio, or Tuner.
The balanced input is desirable for minimizing earth loop generated mains hum and ripple,
or high frequency interference, if a noise problem occurs.
16. GROUND POST. Accepts a ground wire from an external phono stage.
This terminal does not have to be used, but you may connect it to a suitable ground on an
amplifier for example, which under some circumstances will reduce hum and ripple.
17. BALANCED OUTPUTS need to be connected to an outboard amplifier(s).
18. REMOTE CONTROL TRIGGER. Generates a 12 volt DCtrigger signal which will activate
aLUXMAN B-1000f, M-800Aor M-600A. It togglesbetween Stand-By and Operate. Uses
a simple RJ-11 connector (normally used for the phone lines).

19. MAIN POWER Switch. If you are not using your C-1000f for an extended period of time
and want to turn off the power completely.The remote control will not be able to activate
the control amplifier.
20. LINE PHASE SENSOR. Here is a clever device found on the back of almost every Luxman
powered product. You press the button and it will check the phase of the electricity it is
receiving. If the AC outlet in the wall is incorrectly wired, meaning the live and neutral are
swapped, a red LED will turn on to warn you. You only need to press it once, when you are
installing a product to check that everything is in order. It’s a simple mistake, that occurs
often, and one that can undermine your listening enjoyment.
21. AC INLET Connect the C-1000f power cord to a live AC outlet. Refer to information on the
back panel to deter-mine the correct voltage.

1. Operation (On / Stand-by) push button turns the C-1000f either ON or OFF (stand-by).
The muting circuit operates for about 60 seconds after the power is turned on, until
the circuitry stabilizes. No sound is heard during this period.
While the unit is warming up, you will see the legend:
2. Input Selection; select any one of the eight music signal sources, either from the rotary
selector on the front panel or from the remote control. The front panel display will show the
Input Selected on the top line, with the Volume setting underneath, as in:
While the balanced inputs will look like this:

3. Output Mode cycles between modes: BAL →Bi-Amp →UNBAL →.The blue LEDs
will illuminate which outputs are active on the front panel display.
4. Balanced Output Phase Invert; this will invert the phase from where it is set. The
blue LED shows that the phase is inverted.
5. Volume Control; adjust the Volume Control for the desired listening level. The
VOLUME control adjusts the overall loudness of the signals being fed to the loudspeakers.
It is electronic with 72 discrete steps and can be adjusted from the remote control handset.
At this setting the volume is turned off. You can raise the volume using the volume
button.
You should acquire the habit of lowering the volume, when changing between inputs or
before playing a record.

6. Mute (Volume). Press the MUTE Button to temporarily lower the sound to the speakers.
Mute mode is indicated by the active Legend flashing.
Press MUTE again to restore sound. Mute does not affect recordings made using the Tape outputs
(REC OUT) but will affect the signal going to the Preamplifier output (Pre Out).
7. Dimmer (Display) Cycles through four levels of intensity:
Normal →Dim →Dimmest →Display Off →Normal.
8. Output Channel Preset Depends on which Output Mode is selected.
UnBalanced and Balanced offer LR Balance . While Bi-Amp Cycles through two
controls: LRBalance →L-ΗiR−Ηi (Output Balance between the two different outputs)
→LR Balance (Channel Balance between the two different L & R channels)
BALANCE Control will adjust the Balance between the Left and Right channels. Plus or
minus 8 dB.

The C-1000f can be placed upright on a table or shelf, standing on its four feet. It also can be
custom installed in piece of furniture or cabinet of your choice.
Always provide adequate ventilation for your C-1000f. Cool operation ensures the longest possible
operating life for any electronic instrument. Do not install the C-1000f directly above a heat generat-
ing component such as a high powered amplifier. If all the components are installed in a single
cabinet, a quiet running ventilation fan should be utilized to maintain all the system components at
the coolest temperature.
Allow at least 2’ above the control amplifier, 2” all around.

Now you are ready to take advantage of Luxman’s long standing tradition of excellence in the C-
1000f Control Amplifier. The C-1000f’s reproduction is sonically transparent and absolutely accu-
rate.
CD, DVD, SACD, TUNER connection Input for a CD or other line-level signal source. Use
a twin RCA-to-RCA lead to connect the CD player’s left and right ‘Audio Outputs’ to this input.
The C-1000f only accepts analogue signals from your CD player.
PHONO (Record Player)
You will need to connect the output from your phono cartridge to an outboard phono stage (such as
the E-1, E-600 or EQ-88 + MT-88 + OPEQ-88), then connect the output of the phono stage to an
input on the C-600f. If you hear a lot of hum, you will most likely need to run a copper cable
between the record player’s chassis to the phono stage and possibly to the SIGNAL GROUND
(No.21).
Balanced Connection Pin Out
Please refer to Balanced Output Phase Invert; on Page 10 for details on how to change
the phase for the output.

2. Cold –
3. Hot +
1. Ground
2. Hot +
3. Cold -
In the USA, most balanced products use Pin 2 = Hot or +. So Luxman’s Japanese products
use the reverse mode from the American POV. The output phase can be adjusted from the
remote control.
NOTE: Always turn the amplifier off before connecting or disconnecting cables from the Output
sockets.

SUBWOOFER CONNECTION
Quite often there are two ways to connect one or two subwoofer(s) to one’s system.
Speaker output (High Level) or Line Level.
Speaker (High Level) Connection
Simply connect a speaker cable either to the Speaker Terminals and then to the Speaker terminal
INPUT on the Subwoofer. Or alternatively connect an additional speaker cable to the speaker’s
binding post and the other end to the Subwoofer’s Speaker terminal INPUT.
Please ensure that you do not invert the phase by mixing the Left and Right Channel connections.
Best to run one cable at a time and connect Left to Left at each end, then repeat the process for
the Right channel.
Preamplifier (Line Level) Connection
1. Connect the L female RCA (white) end of your interconnect cable to the C-600f’s L OUTPUT
and connect the other end to the L INPUT on your subwoofer.
2. Ditto for the R channel (red), repeat as above.
HOME THEATER PROCESSOR
In the situation where you would like your C-1000f to drive the front Left and Right speakers of your
Home Theater audio system and still be able to enjoy stereo CDs & LPs played through the C-
1000f.
1. Connect an RCA cable from the Output of you HT Processor, this will connect to the input that
you assign of the C-1000f.
2. Select the assigned input on your Luxman control amplifier from the Input Selector
3. Set the volume control to -21 dB. (Actual Unity Gain is -11 dB)
4. Now calibrate the output volume of your Home Theater Processor to have an
equal amplitude measurement from all your multi-channel speakers as measured at
the central listening position.
5. When you are finished with the Home Theater and want to listen to music again, simply turn
the volume back down to -50 dB and change inputs.
6. You should acquire the habit of lowering the volume, when changing between inputs or before
playing a record.
