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.
The M1000 is a natural choice for every
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.

(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.

(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.
REMOTE CONTROL
The remote control duplicates the functions of the 5 button controller on the front of the M1000, plus adds some
additional functions such as power on/off, mute on/off, and 1 button selection of the 5 EQs. In a typical home
theater installation however, the remote will most likely NOT be used as the M1000 will be configured to a specific
subwoofer and room placement, and controlled by the main processor or receiver.

M1000 is put into Standby Mode by turning the amplifier off through either the remote, the auto off mode or the
12V trigger. Also, if the amplifier overheats, the standby indicator will come on as the amplifier will go into
standby mode.
3Clipping Indicator - The word Clip will flash in red when the power output exceeds the 1000W power
rating of the amplifier. Although running the M1000 into clipping is not recommend for sonic and woofer
reliability reasons, occasional clipping is generally acceptable on music and movie sources due to their very
dynamic nature. However, if any distortion is heard the amplifier level should be reduced.
4Signal Indicator - The word Signal will flash in green when a signal is present on the inputs.
5IR sensor/receiver - IR signals from the remote control are received here. If a IR sensor is plugged into the
rear IR input jack, this sensor will be turned off.

LCD DISPLAY SCREENS/FUNCTIONS
Normally, the LCD display will show the status for a number of DSP settings as well as the volume level and a
flashing output level bar display. The “normal” display is show below.
Navigation through the DSP menus and DSP settings are done via the 5 button controller on the front of the M1000
and the 5 button array on the remote control.
When in the Normal mode, pressing the left/right buttons will allow volume adjustment and the display will change to
volume mode (see below).
Pressing the “enter” button will switch to the DSP setting mode and the first screen to appear will be the “Subsonic
Freq” display. From that point, the “up” and “down” buttons will scroll through the different setting screens as listed
below. The left and right buttons will allow you to set the options for any screen. If you accidently get to a screen you
wish to exit, do not press a button for 3 seconds and display will revert back to the “normal” mode. You can also
select the default setting again.
On each DSP display screen, the current DSP default setting will be displayed. If you use the left/right buttons to
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.

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
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.

Mode Select
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.
Crossover Freq
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.
EQ Mode
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.
User EQ Setup
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.

Crossover Slope
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.
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.
