INTRODUCTION
The James M1000 is a high performance, class D, subwoofer amplifier capable of delivering a minimum of
1000W of clean power at 4 ohms. It uses advance DSP technology to allow sophisticated optimization of the
amplifier’s parameters to match the subwoofer being used and the environment in which the subwoofer is
installed. The M1000 features a large LCD display and 5 button controller to allow configuration of all DSP
settings. On the front panel there are black-out indicators for power, standby, clipping and signal presence.
Upon startup, the display will show the firmware revision number.

INSTALLING RACK MOUNT EARS
If you plan to install your M1000 into a standard 19-inch rack, you must install the supplied rack ears.
(1) Remove the 6 screws from the sides n ear the front of the M1000 (3 on each side).
(2) Using the same screws, attached the supplied rack ear s to the M1000. If required, the 4 feet can also be
removed at this time by unscrewing the feet mounting screws located in the center of each foot.
(3) Due to the weight of the M1000, it is recommended th at the rear flanges be secured to the rear rack rails.
Hardware to do this is not supplied with the amplifier and is specific to the type and depth of rack you are
using. You are responsible to source the proper hardware to secure the rear mounting points.
Rear Rack Mounting Tab Installing Front Rack Ears
CAUTION!
The M1000 amplifier is convection cooled and does not use a fan to eliminate noise and allow it to be
used in the listening environment. For this reason, ensure there is adequate ventilation above and below
the amplifier when rack mounted. Avoid placing heat generating equipment below it in the rack. If the
M1000 does not receive enough ventilation, if may overheat and switch to standby mode.
AC LINE VOLTAGE
The M1000 can be used on 110V-120V, 60Hz or 220v-240V, 50Hz AC lines. To change the operating line
voltage:
(1) Turn the power off using the rear power switch.
(2) If required, remove the IEC line cord and replace wi th an IEC AC cable that matches the AC wall socket.
NOTE: This should be a 10A rated cable.
Page 3
(3) Remove the plastic cover screws and the plastic cover over the 115/230V selector located on the rear of the
amp. Set the switch to the correct position for the line voltage in your country. Check the fuse and install
the correct value if needed.
(4) Replace the plastic cover and screws over the voltage selector switch.
(5) The M1000 is fuse protected and if you change the AC voltage settlings, you also need to change the fuse
to the correct value. Use only GDA type fuses. Values are listed below
115V OPERATION GDA TYPE 15A 250V
230V OPERATION GDA TYPE 8A 250V
NOTE: A spare fuses is also located in this
holder
INSTALLATION - CONNECTIONS
(1) Attach the audio input cable from your source to the proper input connector(s) on the M1000. Use the high
level binding posts if feeding a speaker level signal from the output of an audio amplifier. Use the XLR line
level inputs if you have a balanced audio signal coming from your receiver or processor. Use the RCA line
level input jacks if using an unbalanced line level source. If feeding the signal from the LFE output from a
home theater receiver or processor, you only need to use one cable and connect to either the left or right
input since the LFE signal is mono.
(2) Connect one end of the speaker wire to the speaker output binding posts observing the polarity and connect
the other end to the subwoofer terminals.
NOTE: All 5-way binding posts have an insulating plug inserted into the end of the post. If you wish to
insert a banana plug as your method of connection, you can insert the banana plug into the wire hole in the
binding post, or you can remove the insulators by popping them out with a small screwdriver.
Page 4
Removing the binding post insulators Inserting banana plugs into wire holes
(3) If you haven’t done so, verify that the amplifier’s AC ma ins selector on the rear of the M1000 is set to your
AC line voltage and you have the correct fuse installed.
(4) Verify that the rear power switch is in the off posit ion. Plug the power cord into the rear IEC connector on
the rear of the amplifier. Connect the other end of the AC cord to an AC power wall socket.
(5) Once all the input, output and power cables are connected, turn the unit on and proceed with the DSP
setup.

be used for a mono LFE input.
12 Left/right XLR balanced inputs - For feeding BALANCED line-level stereo left/right signals. Also, either left
or right XLR jack can be used for a mono LFE input.
13 Left/right RCA outputs - For looping the subwoofer input signal to additional amplifiers. The signal
received by the RCA or XLR inputs is passed out through these jacks and is not effected by the amplifier and
maintains left/right separation. XLR BALANCED inputs are converted to unbalanced RCA output.
14 12V trigger input (3.5mm) - For triggering the power on/off from other devices such as processors or
receivers that have a 12V trigger output. 6V minimum required for triggering.
NOTE: Once in trigger mode, the amplifier cannot be turned on without a 12V trigger signal. To disable the 12V
trigger, turn the unit off, then hold down the left and right navigation buttons while turning the amplifier on with
the rear power switch. The trigger mode will be turned off and the amplifier will power on.
15 External IR input (3.5mm) - For attaching an external IR receiver. Plugging in an IR receiver here will
disable the font panel IR receiver.

select a new option for that setting, you must them press “menu” to select this option.
When scrolling left/right through
the options, the current default will have an asterisk next to it.
Once you have configured all the settings for your product, you can save them as 1 configuration by using the
“Memory Store” screen. In this way, if the settings are
invariantly changed, you can always recall your saved settings
in this way. NOTE: Avoid storing to the Memory 3 location as this is where James stores the configuration for your
subwoofer if it was programmed at the factory.
If James has configured your M1000 for a specific subwoofer, it will be saved in Memory 3 location. This can be
overwritten so avoid saving any settings to the memory 3 location unless advised by James personal.
You can always revert to the factory default settings by recalling “default” in the “Memory recall” function.
Following are further explanations of each DSP screen. Also, a flow chart follows this section with further details.

Volume Control
The “Volume” control is available from the “Normal” screen
and is activated by pressing the left/right pushbuttons. This
feature allows you to adjust the output volume of your
subwoofer amplifier and ultimately, the output of your
subwoofer. The volume should be set to achieve the best
balance between the main speakers and the subwoofer. After 5
seconds, display will revert back to Normal.
Use “left” and “right” push buttons to set.
Subsonic Freq
Mode Select
Crossover Freq
The “Subsonic Freq” setting allows you to limit the low
frequency range of the sub and is generally used to protect
subwoofers from over-excursion and/or damage from operating
below the subwoofer’s tuning frequency. A “flat” setting is
provided to remove the fliter, or a filter frequency can be set
from 16Hz to 40Hz in 1 Hz steps.
Use “left” and “right” push buttons to set and “menu” to save.
The “Mode Select” allows switching the amplifier between
LFE or SUB mode. In LFE mode, the crossover slope and
frequency adjustments are disabled. The crossover frequency
should then be set by an external processor/receiver.
Use “left” and “right” push buttons to set and “menu” to save.
ONLY AVAILABLE WHEN IN SUB MODE.
The “Crossover Freq” setting allows the crossover frequency
to be set from 40 to 160 Hz in 1 Hz increments. For reference,
the crossover slope is displayed in the upper right hand corner.
Use “left” and “right” push buttons to set and “menu” to save.

Crossover Slope
EQ Mode
User EQ Setup
ONLY AVAILABLE WHEN IN SUB MODE.
This “Crossover Slope” setting allows the crossover slope to
be set from 6 dB/octave 36 dB/octave in 6 dB/octave
increments. The higher the slope, the less mid-band
information will get through to the subwoofer, but there will be
greater phase change which might effect the sound of the
system as a whole.
For reference, the crossover frequency is displayed in the
upper right hand corner.
Use “left” and “right” push buttons to set and “menu” to save.
The “EQ mode” setting allows six selections
- “Flat” removes any EQ and provides flat frequency response.
- “User” setting allows the user to adjust and program a
personal EQ curve.
- The 4 presets (EQ1 to EQ4) are factory presets and should
only be used when instructed by the factory.
NOTE: James may rename any Preset EQ to a specific James
Model of subwoofer.
Use “left” and “right” push buttons to set and “menu” to save.
ONLY AVAILABLE WHEN IN USER MODE.
In “User EQ” mode, the user can adjust and program nine 1/3
octave bands from 20 Hz to 125 Hz. (20, 25, 31, 40, 50, 63,
80,100,125 Hz) by using the left/right pushbuttons. At each
frequency, there is a +6 to -6 dB level adjustment in 0.5 dB
steps and can be adjusted by pressing the up/down
pushbuttons. This feature duplicates a typical third-octave
equalizer as show below.
Phase Setting Select
The “Phase” setting is used to adjust the phase/polarity of the
subwoofer to provide the best summing to the main speakers.
The physical placement and distance of the subwoofer in
relation to the main speakers may result in unwanted
cancelation of some of the bass and can be compensated for
by adjusting the phase setting.
The phase setting can be adjusted while listening for maximum
or best bass performance or by using a real time analyzer and
measuring the actual response of the system as a whole.
The phase adjustment is in 45 degree steps from 0 to 315
degrees.
Use “left” and “right” push buttons to set and “menu” to save.

Limiter
The limiter function allows setting the maximum power which will
be supplied by the M1000. This is useful for preventing overpowering smaller subwoofers. Like most audio amplifiers, the
M1000 is a voltage amplifier and delivers voltage to the load.
But the actual power depends on the impedance of the load, so
the limiter is set by -dB, which are independent of actual power
but indicate level reductions. The load on the M1000 can be 1 or
Limiter On
Limiter setting (dB) % of max 8ohm Watts 4ohm Watts
2 subwoofers, as long as the total impedance remains 4 ohms
or higher. The limiter is set in -dB, which is the dB from full power
which at 4 ohms, is 1000 watts, but only 500 watts at 8 ohms. A
-3dB reduction is half the power so 3dB changes are bolded in
the table since they are an easy reference point.
Once a limiter setting of anything but “0” is set, the limiter icon
appears on the display (see illustration) and the red clip indicator
on the front panel, which normally indicates full power clipping,
will now light when the limiter maximum power is reached.

Auto Off Setting
External Trigger Select
The “Auto Off” setting allows the amplifier to turn on and off
based on the presence of an audio signal. When set to “off”,
the function is disabled and the amp stays on constantly. When
set to ON, the amplifier is controlled by the presence, or
absence, of audio signal on the input jacks. When an input
signal is present, the amplifier will turn on immediately. Once
the signal stops, the amplifier will turn off after the selected
time duration. There are duration settings from 5 minutes to 30
minutes in 5 minutes increments. Typically this is used with a
receiver which does not have a 12V trigger.
Use “left” and “right” push buttons to set and “menu” to save.
The “External Trigger” setting is used to allow an external
12V trigger source to turn the amplifier on and off with a 12V
trigger from another device, such as a processor or receiver.
NOTE: Once this feature is selected, the amp will stay in
standby mode until 12V is applied to the 12V trigger jack on the
rear of the amplifier. This means you cannot TURN OFF the
feature unless the amp is on and the amplifier can only be on
with a 12V trigger signal applied. However, it is possible to
bypass the need for the trigger signal and turn the amp on by
doing a special power-on sequence as follows:
(1) Turn the amp off,
(2) Push and hold the left and right pushbuttons on the
DSP navigation control,
(3) While holding the buttons turn the amplifier on with the
rear power switch.
The amp will power on with the external trigger turned off.
Use “left” and “right” push buttons to set and “menu” to save.
Lock Setting
Memory Store Function
Memory Recall Function
The lock setting allows the user to lock the DSP settings in
memory and prevent adjustment via the DSP pushbutton
controls. To lock, set to “Enable”. To turn off the lock, set to
“Disable”.
Use “left” and “right” push buttons to set and “menu” to save.
There are 3 independent memories which can be used to save
all the DSP settings as a single configuration. Once you have
finished programming all the features, select a memory location
(1, 2 or 3) and press Menu to save.
NOTE: memory 3 is used by James to store settings in some
cases so avoid using this location unless you are certain there
is no James setting saved there,
Use “left” and “right” push buttons to set and “menu” to save.
There are 4 memory locations that store 4 independent DSP
settings. Memories 1, 2 and 3 are programmed by the user
using the “Memory Store” function. A 4th setting, “Default”,
resets all the settings back to the factory default.
NOTE: Memory 3 is sometimes used by James to store
settings for a specific product.

THERMAL AND POWER INPUT DATA
INPUT POWER
Generally accepted power levels for thermal and power consumption calculations are 1/8W power input into the
expected subwoofer impedance. 1/8 power approximates usage with little or no clipping of the amplifier and
distortion free operation. 1/3 power equates to severe amp clipping and audible distortion.

APPENDIX C – TROUBLESHOOTING
1) THE AMPLIFIER APPEARS TO HAVE NO POWER (NO LEDs COME ON)
There are a few obvious things to check. Make sure the amp is plugged in to an active AC power receptacle
and if it is a switched outlet, make sure the power is turned on. Make sure the rear power switch is turned on.
Once you have confirmed the AC power is turned on, make sure the voltage selector on the rear of the amp is
set correctly. Having the selector at 230V while plugged into an 115V outlet will keep the amp from turning
on.
Check the fuse located in the IEC power receptacle.
2) THE AMPLIFIER WILL NOT COME OUT OF STANDBY MODE
If the amp was configured to use the 12V trigger, if will only turn on when a 12V trigger signal is applied to the
12V trigger input. If you are not using a 12V trigger, then you can reset the 12V trigger to “off” by turning the
amplifier off, and then turning the amplifier on while holding down the left and right front panel navigation
buttons.
The amp could have overheated. Let the amp cool down.
The amp might have suffered an internal component failure. The amplifier will need to be serviced.
3) THE AMPLIFIER IS ON BUT THERE IS NO SOUND FROM THE SUBWOOFER
Check the front panel to see if the green “Signal” indicator is on or flashing. If so, this indicates a signal is
going into the amp. So the problem will be between the speaker output from the amp and the subwoofer,
most likely an open or shorted speaker wire, or a poor connection at either location, or a bad subwoofer.
Make sure the volume is turned up on the amplifier.
If the green signal indicator does not come on or flash, then there is no signal entering the amp and you
should check the cables running into the amp inputs and the source feeding the signal to the amplifier.
If the amplifier is on, but the red standby indicator is on, check the issues listed in item 2.
4) THE AMPLIFIER PRODUCES A BUZZ/HUM IN THE LOUDSPEAKER
Any buzzing or hum that does NOT change level with the volume control is generally caused by a ground loop
condition. This is especially common when the M1000 is located on a different AC line from the other
equipment or when all the electronics are rack mounted so the chassis’s are all grounded via the metal rack.
Though using a ground lift adapter on the amplifier’s AC plug may cure the buzz/hum issue, removing the
ground may result in an unsafe condition if the amp was to experience a power supply failure. We suggest
the use of a ground input isolator such as the Radio Shack “Ground Loop Isolator”, part number 270-054. An
input isolation transformer can also be used.
If the buzz/hum changes with the volume level, it can still be caused by a ground loop and this should be
checked. But also, the buzz/hum could be caused by a bad input cable, so a cable swap is recommended.
5) NO OUTPUT ON THE RCA LOOP THROUGH RCA JACKS
If you are feeding your signal into the XLR inputs, the initial production run of M1000’s did not feed the XLR
outputs to the RCA loop out jacks. So you will need to use the RCA inputs for these models. This applies to
any serial number starting with 0910.
6) AMP DOES NOT APPEAR TO GET LOUD ENOUGH YET THE CLIP LIGHT IS ON
Check to see if the limiter has been set to a low power level.
