INTRODUCTION
Thank you for choosing Event Electronics™ Project
Studio direct field monitors. Before you proceed, please take a minute to read
this manual and familiarize yourself with the product’s features, set-up and use.
Our engineers have spent years designing transducers, studio
electronics and high performance studio monitoring systems, including some of
the most popular professional speakers used today. Now, using the latest in
digital acoustic design tools, along with high performance driver and power
amplifier technology, we’ve developed the Event Project Studio monitors,
which extend the performance and value limits of direct field monitors again.
Event engineers based these new 100 watt Project Studio monitors on
the sound and reliability of our 200 watt 20/20bas 8” two-way Biamplified
System. Indeed, the new biamplified PS8 monitor uses the same drivers,
enclosure and active 4th order crossover as the 20/20bas monitor, with only 3dB
less maximum acoustic output. The same 100 watt Project Studio amplifier, with
different active crossover and subsonic filters, powers the PS5 and PS6.
The benefits of biamplification include lowered distortion, smoother
amplitude and phase response, extended bandwidth, and convenience. Project
Studio amplifiers feature significant improvements in signal-to-noise ratio, input
common mode rejection ratio, and reliability. They produce less distortion and
less heat as well.
Event Engineers developed the small desktop biamplified PS5 speaker
using shielded driver and active crossover components from our proven Tria
Triamplified Monitor. The PS5’s have a convenient front panel level control
plus a retractable tilt stand for optimum positioning of its wood cabinet in
personal monitoring environments.
The new PS6 6½” monitor uses a new magnetically shielded 6½” LF
driver to go with our proven 1” natural silk dome HF transducer. The PS6 uses
a pair of low restriction bass ports and establishes a convenient intermediate size
for high performance 6” two-way systems.
UNPACKING
Check your speaker carefully. The packing container was
designed to protect your speaker during transit; immediately report any damage
to your dealer or to the company that delivered them to you. The packing
material is designed to be reused—do not discard it. Please complete and return
your warranty card to activate your warranty and to help us keep in touch with
you. Please tell us what you think of your new monitor and of your Event
dealer.
SETUP
The best performance from any speaker system comes with proper
placement and use. There is no physical or acoustic distinction between
individual left and right monitors when they are used in a stereo pair. Also, the
cabinets can sit vertically or horizontally without concern for performance as
long as both are situated similarly. For horizontal mounting, tip the cabinets
outward so that the high frequency drivers are away from each other. Since the
bass port is front mounted, you can mount the speakers near to, or even in, a
wall without blocking the port.

CARE AND MAINTENANCE Your Event Direct Field Monitors will not
require any special care or maintenance if properly used. The cabinet is finished
with a durable vinyl laminate that can be cleaned with a soft damp cloth. Avoid
touching the exposed speaker elements. Do not expose the rear panel controls,
connectors, or the speaker elements to moisture or chemicals.

placement shown in Figure 1.
The AC mains fuse is internal and serviceable by a qualified technician. It will
only open if there is another problem.
Mix at reasonable levels to protect your speakers and your hearing.

BLOCK DIAGRAMS
FIGURE 1. THE PRIME LISTENING POSITION OR SWEET SPOT.
THE DISTANCE BETWEEN EACH SPEAKER AND THE MONITORING
POSITION SHOULD BE EQUAL.
Notice that Figure 1 also shows the speaker cabinets turned inward
directly facing the listening position. This puts you in the sweet spot, which
yields the most accurate stereo reproduction. If you need a wider sweet spot to
allow for greater listener movement or for group monitoring, face the speakers
in a slightly more open position, but never more than necessary. Finally, if you
must mount the speakers substantially above or below ear level, then you will
also need to tilt the cabinets downward or upward as well to keep them directly
facing you.
For close-in, personal monitoring situations with the PS5, use the tilt
stand if necessary to raise the radiation main axis.
Once you start using your Event monitors, you may find it helpful to
move around in their soundfield to locate their best position in your
environment, but if you follow the equal distance, ear level, face-on rules,
you’ve already optimized their position for a single user in most situations.

Place your monitors on a stable surface at about ear level. A typical
location would be slightly behind and to either side of a small console. The
distance between the monitors should equal the distance from the listener to

CONNECTIONS AND OPERATION
Please refer to Figure 2
balanced or unbalanced. The LINE 2 INPUT connector is hardwired in
parallel with the LINE 1 INPUT connector, so either may be used as an input
or a pass-through connection. Input specifications apply to both inputs.

LINE 1 INPUT This jack accepts a ¼” TRS connector, wired either
balanced or unbalanced.
For balanced wiring, a 3-conductor ¼" TRS plug is necessary. See
the INPUT CONNECTIONS wiring chart below or on the amplifier
panel.
Unbalanced wiring works with either a 2 or 3-conductor ¼” TRS
connector. A 2-conductor ¼" TS plug automatically grounds the
minus signal input, whereas a 3-conductor TRS plug wired
unbalanced provides the option of leaving the minus input open or
grounded. We recommend that you ground the unused input.
The LINE 1 INPUT connector is hardwired in parallel with the LINE 2
INPUT connector, so either may be used as an input or a pass-through
connection. Input specifications apply to both inputs.

INPUT SENSITIVITY This control has a 20dB range and compensates for
different input signal levels. If too much input signal is present, the amplifiers
may overload, in which case the green LED at the front of the monitor will
flash. With the INPUT SENSITIVITY control at maximum, 0.9V RMS input
will produce full amplifier output.
The PS5 monitor has an additional front panel VOLUME CONTROL (not shown)
that effectively works in series with the rear panel INPUT SENSITIVITY
control. The VOLUME CONTROL is useful for quick, uncalibrated adjustments
from the front. With a full input signal applied, turn the front panel VOLUME
CONTROL to maximum. Starting from minimum, increase the INPUT
SENSITIVITY to your maximum achievable output level preference. The front
panel volume control will then attenuate from that operating point.

POWER CONNECTOR This connector accepts the detachable linecord. Use
the linecord supplied with your monitors and make sure it is fully seated into
the Power Inlet connector. For safety reasons, do not attempt to defeat the
linecord’s ground connection. The AC mains fuse is internal.
