INTRODUCTION
Congratulations on your purchase of the PM 4040 speaker system. The PM 4040 set comprises an active
and passive monitor, wired as left speaker and right speaker. It uses high grade transducers - a 4" glass-
fiber cone woofer, and a 25mm neodymium magnet dome tweeter with an elliptical waveguide built into the
front panel, housed in a bass-reflex type rigid MDF enclosure. These are driven by a highly efficient Class-D
amplifier. A choice of balanced and unbalanced inputs on rear panel, an additional unbalanced input through
Aux on the front panel, front-mounted headphone output and volume control, provide all the essential
features required of such a monitor.
SAFETY
• Please ensure proper earthing.
• Please keep away from moisture.
• Ensure that the speakers are not covered while in use. Restricted airflow at the rear of the unit will
cause it to heat up.
UNPACKING
While removing the units from the carton, please do not hold the speaker’s front. The high frequency
transducer is located near the top of the cabinet, on the front baffle; you may accidentally damage the
transducer.
The best way to safely unpack the monitors is to open the top of the carton, spread the flaps of carton wide
apart and turn the entire carton upside down.Then simply pull off the carton. Next remove the packing
buffers and protective bag

CONTROLS & FEATURES
PM 4040 page 3
FRONT PANEL (Refer to Fig. 1 on page 2)
1. VOL. CONTROL
This controls the level of both the left and right speakers. Use it to set the listening volume
2. POWER INDICATOR
This lights up when power is ON
3. PHONES
Connect a pair of 1/8th headphones to this socket if you wish to monitor through headphones.
Note that the internal speakers will get disconnected when you plug in the headphone jack.
4. AUX IN
This is a 3.5 mm stereo socket for connecting a line-level unbalanced input.
REAR PANEL (refer to Fig. 1 on page 2)
1. UNBALANCED INPUT
This is an RCA unbalanced type input. Connect your source to this socket if it has an unbalanced
input
2. BALANCED INPUT
This is a fully balanced TRS input socket.
Pin connections are TIP-Positive, RING-Negative, SLEEVE-GND
3. SPEAKER TERMINALS
There are a pair of speaker terminals on both the active speaker (left) and the passive speaker (right).
These are to be connected with the speaker cable supplied. Take care to connect the + terminal of
one speaker to the + of the other speaker, and vice versa.
4. POWER SWITCH
This switch is used to turn power on or off
5. AC SOCKET
This is a fused 3-pin IEC AC receptacle for connecting to a wall outlet with the cable supplied. Ensure
that the wall outlet is properly earthed, that is, the earth must be connected to a earth bus-bar which
connects to other audio equipment and is not shared by noisy equipment like computers, air-
conditioners, lighting appliances etc. The earth connection is also required in the interests of your
own safety, should any fault occur. Please check that the wall outlet is capable of providing the current
requirement of the product, printed on the back panel near the IEC AC socket.
6. OVER-VOLTAGE PROTECT LED
The PM 4040 has a protection feature which automatically shuts off the power when the mains
voltage crosses an upper limit. In such case, this LED will glow. Normal operation will resume when
the over-voltage condition is removed.

INSTALLATION • FIG. 2
ROOM PLACEMENT
The PM 4040 has a wide variety of placement options. Shown in Fig. 2 is a typical stereo setup for near field
monitoring.
The monitors should be angled to directly face the listener. The center of the high frequency transducer
should be on-axis with the ear level of the listener. Keep the PM 4040 at least 2" away from rear wall so as
not to block the port on rear
LISTENING DISTANCE
The common listening position at mixing positions is generally 1 to 1.5m for near field applications. The
stereo listening angle is more a matter of personal preference, but we recommend the angle should be
around 60° as shown in Fig. 2
MOUNTING OPTIONS
For mounting the speaker on a wall 2 inserts are provided on the base as shown in Fig. 3

OPERATION
Connect the speaker terminal on the passive or R speaker to the speaker terminal on the active or L speaker
with the cable supplied. Take care to maintain correct polarity
Connect the line level monitor signal from your mixer (or any other source) to the signal input on the PM
4040 using balanced cables (3 pin XLR).
Connect the supplied AC power cord to the IEC socket at rear panel. Keep the power switch at OFF position.
Keep the volume control on PM4040 at minimum Switch on your source.
Switch on PM 4040. The blue power LED will light up.
Adjust the volume to get the desired listening level.
NOTE Your PM 4040s achieve their best bass response in a room that is optimized for bass reproduction.
Factors such as room shape and volume, absence of acoustical treatment can prove to be a bane for optimal
sound reproduction from the PM 4040.
MAINTENANCE
No user serviceable part is present inside the unit. All maintenance and repair work are to be undertaken by
qualified personnel only.
