INTRODUCTION
Congratulations and thank you for purchasing the Procient Audio M2 Two Channel Power Amplier.
The M2 combines the best of styling and performance in a truly solid amplier that can handle just about
any high power audio application.
With discreet components and high current output, the M2 delivers clean, powerful sound in any application. Whether used for critical listening in a two-channel music room or crankin’ the tunes by the pool, M2 is
the perfect amplier when it’s the sound that counts. M2 is right at home adding extra rooms of high powered audio to an A/V Receiver, 2 zone surround receiver or multiroom audio controller.
For systems where high powered audio is needed in multiple rooms, the M2 Loop Output can be used to
connect up to four additional M2s for up to ve rooms of high powered amplied audio.
With 125 Watts per channel, (235W @ 4Ω) of power, the individual channel Level Controls can be set to maximum output levels to protect the amp, and the speakers, from driving the amp to clipping or driving the
speakers to improper levels.
Optional Audio Sensing automatically turns the M2 ON and OFF with the rest of the system. Simply turn on
the A/V Receiver, play a source and get ready to experience the power of the Procient M2.
The M2 is more than a solid performer, it looks good too. The cast aluminum Front Panel is like no other and
makes an impressive addition to any stack of gear.
Fully Featured. Solid Performer. Great Looking. Home entertainment never looked and sounded this good.
Please read and follow the instructions in this guide to assist in proper installation connection and use of the
Procient M2 Two Channel Power Amplier.

AIR FLOW
The Procient M2 is designed to run cool under most normal operating conditions but may run warm at moderate to high output.
It is typical for an discreet component, high current amplier to generate a certain amount of heat dissipation that needs to be
properly ventilated.
Closed spaces such as equipment cabinets and racks can get hot with the heat generated by microprocessors and motors in various devices. Providing proper ventilation for good air ow will help keep the temperature down and protect not only the M2 but
all system components and help preserve their longevity.
When installing the M2 a few easy steps should be taken to assure proper air ow:
1. Never block the vent holes on the top or bottom of the M2.
2. Never remove the feet on the bottom of the M2.
3. Leave at least 2 inches above and 1 inch on each side of the M2 for free air ow.
4. Whenever possible, provide vent holes in the shelf under the M2 to increase air ow into the bottom of the unit.
5. Leave the back of the cabinet as open as possible for good air circulation.
6. Place other system components on separate shelves.
7. Install fans in cabinets and racks when equipment is generating high heat levels.

Diagram 4 Speaker Placement
SPEAKER PLACEMENT
Use the following recommendations when determining speaker placement.
Front
Right
Determine The Ideal Listening Zone
The area where the user will most likely be sitting when listening to the speakers is the Ideal Listening Zone.
Placement of Stereo Speakers
The distance between the left and right speakers should as closely equal the distance from one speaker to the listener as possible. (A=B=C) The left and right speakers should also be equal distances from a TV or Video Display for balance with audio/video
content.
Bookshelf Speakers
In audio/video applications when using bookshelf speakers, locating the speakers at the same height as the TV or Video Display
and at equal distances to left and right of the Video Display will create an eect where the sound emanates from the picture.
Inwall Speakers
Ideally, speaker placement should be similar to that described for bookshelf speakers. Many brands of inwall speakers, including
most Procient models, have pivoting tweeters that can ‘focus’ the high frequency content directly to the Ideal Listening Zone
and compensate for sometimes less than desirable placement so the sound will still be balanced with the Video Display.
Ceiling Speakers
Ceiling speakers are very popular in modern architecture. Ceiling speakers, like bookshelf or inwall speakers, should be placed at
an equal distance from each other and the Ideal Listening Zone. Many Procient ceiling speakers have pivoting tweeters that can
‘focus’ the high frequency content directly to the Ideal Listening Zone and compensate for sometimes less than desirable placement so the sound will still be balanced with the Video Display.

INSTALLATION
Speaker Wire
WIRE REQUIREMENTS
Use the following recommendations for speaker wire runs.
Speaker Wire
If connecting the M2 for multiroom audio, pull two pair of
speaker wires from the M2 location directly to each speaker in
home runs, (each run direct from the M2 to each speaker).
1. Pull 1 run of 16AWG (min) 2-conductor stranded speaker
wire from the M2 location to each speaker in a home run
conguration. Leave extra length (24 inches) on both ends
to work with when making connections. (4-conductor wire
can be used by running the 4-conductor wire to an entry
point in the room and then splitting into two runs of 2-conductors, one run (pair) to each speaker.)
In new construction, the wires should be pulled before the drywall is installed. In retro-t applications, (existing construction)
the wires will need to be pulled through the walls and holes
will need to be cut in the drywall for the speakers. It is highly
recommended that an audio/video installation professional be
hired to do this type of work. Contact the retailer that the M2
was purchased from for information on professional installation.
Use the Speaker Wire Length Chart to determine the proper
wire gauge based on actual overall wire length from the M2 to
the speaker pair it will be driving.
SPEAKER WIRE LENGTH SPEAKER WIRE GAUGE
150’ (46m) 16 AWG
400’ (122m) 14 AWG
1000’ (305m) 12 AWG
Diagram 5 Bare Wire Connections
SPEAKER CONNECTIONS
1. Use 16AWG (min) 2-conductor stranded speaker wire for
speaker connection. (Refer to the Speaker Wire Length
Chart for wire runs over 150’.)
2. Strip approximately 1/2 to 3/4 of an inch o the ends and
twist the strands together so there are no loose ends that
can cause shorts.
3. Loosen the Left Channel Speaker + and - Terminals as
shown in Diagram 5 so there is enough room between the
post and the collar to feed the striped wire through without
damaging the strands.
4. Tighten the post to secure the wire.
5. Repeat for the Right Channel + and - Terminals.
6. Conrm connection and polarity.
7. Connect the speaker wires to the appropriate left and right

SYSTEM APPLICATIONS
SYSTEM APPLICATIONS
The following pages will provide three M2 system examples: multiroom, home theater with a second zone and a high powered
zone in a multizone system. These are by no means the only uses for this amplier. The M2 can be used for just about any application where high powered audio amplication is required. For assistance with M2 applications, please call Procient Audio Technical Support at 877.888.9004 or email techsupport@procientaudio.com. Procient Tech Support is open every weekday, except
holidays, between the hours of 7:00AM and 5:00PM PST.
Multiroom
The multiroom system shown in Diagram 12 features the M2 when used to add an additional room of high powered amplied
audio to an A/V Receiver, (coincidentally a Procient M40). This system is a single-source system, meaning the same source will be
played through all active speakers at the same time. The system shown allows anywhere from one to ve rooms of audio depending upon conguration.
Note: The M40 allows direct connection of two pair of speakers, or up to four pair if using impedance matching volume controls.
Those speakers/volume controls are not shown in Diagram 12. Please refer to the Owners Manual if using another brand receiver
for information on speaker connections/limitations.
Audio/Video sources are connected to the M40 Receiver in a normal manner. They are selected and played in a normal manner using the front panel controls or a remote control. When a source is selected it will play through all active speakers. With this type of
system, it is best to set a master volume on the Receiver and use the individual room volume controls to adjust volume.
Input
The M2 is connected to the M40 Receiver Pre-Out. The Pre-Out is a variable line level audio output that is connected to the M2
INPUT. The M2 INPUT audio signal will output through the speakers connected to the M2.
1. Connect the M40 Pre-OUT to the M2 INPUT.
Loop
The M2 LOOP is a xed line level audio output that can be used in a number of dierent ways. In the example shown, the LOOP is
being fed back to the M40 Receiver Main IN. The M40 features a pre-out/main in connection for various purposes. In this case, that
connection will be used to insert the M2 into the source audio signal path. That is: when a source is selected, it will output from
the M40 Pre-OUT. Via the M2 INPUT connection, the M2 will be fed the source audio signal. LOOP will output that same audio signal back to the M40 Main IN which feeds the M40 amplier. In this conguration, if the M2 LOOP is not connected to the M40 Main
IN, the M40 will not output amplied audio.
1. Connect the M2 LOOP to the M40 Main IN.
The LOOP can also be used to add additional M2 ampliers for additional rooms of high powered amplied audio. Up to ve total
M2s can be connected in this manner.
1. Connect the M2 LOOP to the next M2 INPUT. Repeat to connect up to ve M2s (5 high powered amplied rooms).
Audio Sense Switch
For convenience, the M2 can be setup to turn ON/OFF manually (Standby) or automatically (Audio Sense) when the M40 is turned
ON/OFF. The manual mode should be used if the high power room is only going to be used occasionally, (outdoor area, where it
would not be neighborly to crank up the music at 1:00 in the morning). Audio sensing should be used for a room that is to always
turn ON/OFF when the M40 is turned ON/OFF.
Manual Power (Standby)
1. Set the Audio Sensing switch to Standby.
2. Turn the M2 ON/OFF as needed by pressing the Front Panel ON/OFF button.
Audio Sensing
Requires no additional connections. When the M2 detects audio at the INPUT it will automatically turn ON.
1. Set the Audio Sense switch to ON.
2. Set the Front Panel ON/OFF button to the ON (in) position.

SYSTEM APPLICATIONS
Home Theater Plus Second Zone
The multizone system shown in Diagram 13 features the M2 when used to add a room of high powered amplied audio to the
Zone 2 OUT on an A/V Receiver, (in this case a Procient M80). This system is a two zone system, meaning two dierent sources
can be played at the same time. The home theater is Zone 1 and can select any source connected to the M80. The M80 features a
Zone 2 OUT that can output line level audio and composite or S-Video. (For purpose of example only the Zone 2 audio connections will be detailed here. Please refer to the M80 Installation and User Guide for additional information.)
Note: The M80 allows connection of 5.1 or 7.1 surround speaker congurations. Those speakers are not shown in Diagram 13.
Please refer to the Owners Manual if using another brand receiver for information on connections/limitations.
M80 Source Connections
Audio/Video sources are connected to the M80 Receiver in a normal manner. In the theater zone, they are selected and played in
a normal manner using the front panel controls or a remote control. Sources are typically selected and controlled in Zone 2 using
an IR Remote via an IR repeater system. The selected sources can be the same in both zones or a dierent source in each zone. The
source selected by Zone 2 will play to all rooms in Zone 2.
The M80 features analog and digital audio and video inputs. Any of these inputs can be selected by the home theater. Zone 2 can
only select analog audio inputs, therefor any source that is to be played in Zone 2, must have analog audio connections to the
M80.
Input
The M2 is connected to the M80 Receiver Zone 2 Pre-Out. The Zone 2 Pre-Out is a variable line level audio output that is connected to the M2 INPUT. The M2 INPUT audio signal will output through the speakers connected to the M2.
1. Connect the M80 Zone 2 Pre-OUT to the M2 INPUT.
Loop
Source selection and audio processing for the home theater zone and Zone 2 are completely independent. The M80 Zone 2 PreOUT is a dedicated line level audio output. It is not necessary to feed the M2 LOOP back to the M80.
The LOOP can also be used to add additional M2 ampliers for additional rooms of high powered amplied audio. Up to ve total
M2s can be connected in this manner.
1. Connect the M2 LOOP to the next M2 INPUT. Repeat to connect up to ve M2s (5 high power amplied rooms).
Audio Sense Switch
For convenience, the M2 can be setup to turn ON/OFF automatically when M80 Zone 2 is turned ON/OFF.
Audio Sensing
Requires no additional connections. When the M2 detects audio at the INPUT it will automatically turn ON.
1. Set the Audio Sense Switch to Auto ON.
2. Set the Front Panel ON/OFF switch to the ON (in) position.

SYSTEM APPLICATIONS
Multizone High Power Zone
The multizone system shown in Diagram 14 utilizes the M2 for a high power zone with a Procient M4 Multiroom Audio Controller. The M4 allows independent ON/OFF, source selection and volume control by zone. Each zone features it’s own amplier that
typically gets connected to a dedicated pair of speakers for that zone.
Note: The speakers that would typically be connected to Zones 1, 2 and 3 are not shown in Diagram 14.
Each Zone on the M4 Multiroom Audio Controller features a dedicated zone Pre-OUT. It can be used, as shown in the example, to
output line level audio for the source selected in that zone to an external amplier. The amp could be a high power two-channel
amp or a multichannel amp. In this case, the M2 will be used to create a high power zone.
Adding a High Power Zone
Zone 4 is a large room using large speakers with high power handling capability and requires a high powered amp to ll the room
to a good sound level.
Input
The M4 Zone 4 Pre-Out is connected to the M2 INPUT. The M4 Zone 4 audio signal will output through the speakers connected to the M2.
1. Connect the M4 Zone 4 Pre-OUT to the M2 INPUT.
2. Set the M4 Zone 4 VC/NVC (volume control/no volume control) switch to VC. Volume will be adjusted using the M4 Zone
4 keypad or remote control.
Audio Sense Switch
For convenience, the M2 can be setup to turn ON/OFF automatically when M4 Zone 4 is turned ON/OFF.
Audio Sensing
Requires no additional connections. When the M2 detects audio at the INPUT it will automatically turn ON.
1. Set the Audio Sense Switch to Auto ON.
2. Set the M2 Front Panel ON/OFF switch to the ON (in) position.
