INTRODUCTION Thank you for choosing Event Electronics™ 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 over 25 years designing transducers, studio
electronics and high performance studio monitor 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 20/20, 20/20p and 20/20bas systems,
which extend the performance limits of direct field monitors once again.

For years, small to mid sized monitors have been built using the two­way format employing a 6½-7" diameter woofer. Event engineers have
developed an extended range 8" woofer that precisely blends with our reliable 1"
silk dome high frequency driver to produce an exceptionally smooth frequency
response with the deeper bass and bigger soundfield typical of a larger speaker.
The front-mounted low air restriction bass port also adds to our monitors’ larger
acoustic signature. The 20/20bas Bia mplified System monitors build on the
foundation of the passive 20/20 and realize the proven benefits of
biamplification, including lowered distortion, smoother amplitude and phase
response, extended bandwidth and convenience. The unique configuration of
the 20/20p Powered Monitors with its passive crossover provide many of the
performance benefits and all the convenience of a self-powered monitor system
without the high cost.

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. Also, 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.

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

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.

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.

20/20 CONNECTIONS TO AN EXTERNAL POWER AMPLIFIER The

passive Event 20/20 monitors present a 4 ohm nominal load impedance to the
amplifier. Amplifiers rated for 8 ohm minimum loads are generally not suitable
and may even suffer damage if used. We recommend using a power amplifier
rated in the range of 100-200 watts per channel into 4 ohms. Higher power
amplifiers can be used with caution, but care must be taken to never exceed the
20/20 monitor’s 150W program/200W peak ratings. Event is not responsible for
damage caused by overpowering the speaker’s components.

Connections to the monitors are made via 5-way binding posts on the
rear panel. These terminals will accept large diameter bare or tinned wires,
spade or pin terminals, or banana plugs. Use the shortest length of #10 to #14
