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 amplifier. The M2 can be used for just about any applica-
tion where high powered audio amplification is required. For assistance with M2 applications, please call Proficient Audio Techni-
cal Support at 877.888.9004 or email [email protected]. Proficient 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 amplified
audio to an A/V Receiver, (coincidentally a Proficient 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 five rooms of audio depend-
ing upon configuration.
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 us-
ing 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 fixed line level audio output that can be used in a number of different 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 sig-
nal back to the M40 Main IN which feeds the M40 amplifier. In this configuration, if the M2 LOOP is not connected to the M40 Main
IN, the M40 will not output amplified audio.
1. Connect the M2 LOOP to the M40 Main IN.
The LOOP can also be used to add additional M2 amplifiers for additional rooms of high powered amplified audio. Up to five total
M2s can be connected in this manner.
1. Connect the M2 LOOP to the next M2 INPUT. Repeat to connect up to five M2s (5 high powered amplified 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.
