Introduction  
Thank you for purchasing the Fostex PM-1 MK  
Professional Studio Monitor. As with all  
Fostex products, the PM-1 MK has been  
designed to provide superlative performance,  
unquestioned reliability and exceptionally  
high value.  
The PM-1 MKwas specifically engineered to  
fulfillall of your critical near-field monitoring needs  
and is emblematic of the years of experience  
Fostex has had in the professional audio  
marketplace. The PM-1 MK takes full advantage  
of internal bi-amplification and employs two  
state of the art amplifiers that utilize high-  
quality discrete bipolar output devices. The  
6½" woofer and 1" tweeter were expressly  
designed for high output, ultra low distortion  
and incorporate the latest technologies and  
manufacturing techniques.  
Please take the time to thoroughly read this  
manual so that you may take full advantage  
of all the benefits of the Fostex PM-1 MK  
Professional Studio Monitor.  
Unpacking  
Prior to unpacking your Fostex PM-1 MK  
excessive damage. Once it has been determined that the packing material has not been  
compromised, carefully unpack the PM-1 MK Studio Monitor and inspect it carefully for obvious  
Studio Monitor, carefully inspect the packing material for  
damage. Fostex takes great care in designing packing materials that will survive most expected  
impacts during shipping. If any damage is discovered during the inspection process, contact your  
Fostex dealer so that this issue can immediately be addressed.

Setup Instructions  
Monitoring Distance = 1 to 2 meters  
After carefully unpacking the PM-1 MK  
Professional Studio Monitor, it is now  
time to setup the monitors for the best  
acoustic performance in your studio.  
The PM-1 MK was designed to be used  
at a monitoring distance of 1 to 2 meters,  
typically referred to as the near-field.  
Monitoring Height = the acoustic  
center aimed at seated ear height  
It is recommended that the PM-1 MK  
be  
located in such a way that the acoustic  
center is located at, or about, seated ear  
height (see Figure 1). If this is not  
possible, it may be necessary to tilt/aim  
the monitor at the listeners ears.  
Monitoring Angle = 60 Degrees  
The monitoring angle between the left  
and right monitors and the listening  
position should equal 60 degrees. The  
easiest way to determine this is to place  
the speakers in such a way that the  
distance between the left and right  
monitor is equal to the monitoring  
distance / listening position (see Figure  
2). It is also recommended that both  
speakers be "toed-in" towards the  
listening position.  
Additional Information  
The PM-1 MK was designed to be mounted  
vertically. This provides for the most  
accurate frequency response, reduces  
acoustic boundary interference and  
provides optimum cooling performance  
for the heat sink that is located on the  
back of the studio monitor. If it is not  
possible to mount the monitors vertically,  
then the monitors should be placed with  
the woofers inside and the monitors  
"toed-in" towards the listening area.

SetupInstructions continued  
Once the studio monitors have been placed in their final location, it is time to proceed to connecting your  
PM-1 MKstudio monitors to the mixing console or digital workstation. Connection to the PM-1 MKcan be  
made using XLR or TRS connectors. The gain control on the back of the monitor allows continuously variable  
adjustments to match most input types from -10dBV to +4dBu. The input is electronically balanced and is  
compatible with unbalanced sources, although this may require an adapter. The connection of the PM-1 MKⅡ  
to the console/digital workstation should be done in the following order.  
Step 1: Make sure that all equipment has been powered down.  
Step 2: Confirm that all gain controls, on the monitor and the source, are set to the minimum setting.  
Step 3: Connect the source to the PM-1 MKmonitor.  
Step 4: Power up the all source equipment and then turn on the PM-1 MKlast.  
Step 5: Set the gain of both monitors at medium setting and slowly bring up the gain of the console.  
Step 6: Adjust the gain of both monitors for balance and for best signal to noise ratio  
Once the above steps have been completed, you are ready to use your PM-1 MKmonitors. It is  
recommended that you now play some familiar audio material and make any final adjustments, as far  
as placement or level, to get the optimum performance in your monitoring environment.

Cable and Wiring Information  
Use high-quality, shielded cables to connect your mixing console, workstation or other source to your  
monitors. Foil-shielded cables, such as Beholden 8451, 8761, or 9501 should do quite well. Other high  
quality cables are available and those that incorporate better shielding will yield an overall higher noise  
rejection, lowering your systems susceptibility to external interference. Another important tip to keep in  
mind when wiring your system is to route all line level cables away from the AC and other power  
sources, this will reduce the probability of having AC hum emanating from your studio monitors.

ProductCleaningInstructions  
Prior to cleaning the PM-1 MKmonitor the power must be disconnected from the PM-1 MKmonitor.  
Once the power has been terminated, cleaning can be accomplished using a damp (not wet) cleaning  
rag. A light common house hold cleaner can also be used, but care must be taken not to use harsh  
cleaning fluids. Regular dusting or cleaning with a damp rag will keep your product looking new for years.
