Studiophile AV 40 Features
3
1. Woofer
The woofer unit is 4" in diameter and is
magnetically shielded to protect your computer
video monitor from interference. It includes a
high-temperature voice coil and 4" polypropylene
treated paper cone. The woofer delivers balanced
mid- and low-frequency response.
2. Tweeter
By employing a specially developed 1" treated
silk dome with protective magnetic shielding,
the tweeter can deliver an extremely natural
response. It minimizes resonance by adapting a
unique internal damping technology.
3. Bass Reflex Port
The hole in the rear panel is a bass reflex port.
It is designed to discharge very low frequency
signals and enhance the overall bass response.
4. Bass-Boost Control
The back panel Bass-Boost control on the
Studiophile AV 40 gives you additional low-
frequency gain and makes the monitors versatile
for different spaces and listening preferences.
5. Enclosure
Along with the other components, the Studiophile
AV 40's enclosure plays an important role. In
order to provide more stable performance, we
used a special medium-density fiberboard (MDF)
and unique interior reinforcement designed to
absorb vibration and impact generated under
extreme conditions. Additionally, our innovative
speaker monitor cabinet includes carefully placed
acoustic material that makes the Studiophile AV
40 sound much bigger than it is—resulting in a
smooth, natural bass response.

6. Stereo Auxiliary Input
and Headphone
Output
For maximum flexibility, we have included a
stereo “Aux” input which allows you to plug in a
secondary audio source (such as your portable
music player) in addition to the main RCA and
1/4" TRS inputs in the back. The volume control
works on all inputs simultaneously. Additionally,
there is a stereo headphone output next to the
“Aux” jack that mutes the sound coming out of the
speakers and redirects it to your headphones.
7. Network & Power
Amplifiers
The power amplifiers and crossover network, for
the Studiophile AV 40 are specially designed for
this woofer and tweeter. The network distributes
low-, mid-, and high-frequency audio signals
to the proper components in order to minimize
distortion and to achieve a balanced sound.
Installation
4
For optimal performance of the Studiophile AV 40, please read the following directions carefully before installation.
Precautions
Connections: Your Studiophile AV 40 monitors have a variety of inputs for use with a multitude of
devices. Soundcards or other devices with RCA line outputs (e.g., M-Audio Delta Audiophile 24/96)
can be connected to the RCA inputs on your left speaker’s back panel. Professional audio devices
with balanced or unbalanced 1/4” outputs should be connected to the 1/4” TRS back panel inputs. If
your soundcard or portable music player has an 1/8” output, you can connect it to the front panel aux
input, using the provided 1/8” to 1/8” cable.
Correct Power Operation: Since the Studiophile AV 40 contains amplifiers, it must be connected
to a power outlet using the detachable AC cable that is provided. Before connecting power, please
make sure that the On/Off switch on the back of the Studiophile AV 40 is set to the off position.
WARNING! - Use of improper voltage may result in hazardous conditions and/or damage to speaker
components not covered by speaker warranty. Please make sure the voltage is set appropriately
by checking the the position of the red "AC Select" switch on the back before powering on your
speakers.

Acoustic/Traction Pads
In order to minimize vibrations and maximize
physical stability, we recommend you use the
provided acoustic/traction pads on the bottoms
of the Studiophile AV 40 monitors.
Speaker Wire
Connections 1
Use the transparent tinned bare wire cable
included in the Studiophile AV 40 package to
connect the Left and Right speakers via the red
/black spring-clip terminals on the back of each
speaker.
Connecting to a
Computer Sound Card
or Other Audio Output
Device 2
Before connecting the Studiophile AV 40
monitors, make sure the power from the computer
or other output device has been turned off and
the Studiophile AV 40 system is also turned off.
Connect the 1/4" or RCA input jacks to the
corresponding output connectors of a computer
sound card, portable music player, etc. You
can also use the black 1/8" stereo mini cable to
connect a secondary audio device to the “Aux”
input on the front of the Studiophile AV 40.
Setting the “Bass Boost”
EQ Switch 3
This 2-position switch provides a subtle increase
in bass response. The On mode increases
the low-frequency gain slightly via the woofer
and bass-reflex port. The Off mode produces
a natural, even response for most listening
conditions.
Please see Appendix C for the “Bass Boost”
frequency response curve.
