introduction
Thank you for purchasing the EVENT Opal. Before you set up your speakers for the
fi rst time, please read through this user manual to ensure you are able to get the
most out of your investment.
The ‘no compromise’ design brief for these speakers was essentially the
impossible. The Opal was to be an 8-inch two-way speaker with the same
dynamic and extended mid-range as the most expensive three-way systems.
It had to feature extended and powerful bass response, and have seamless and
transparent integration through all the frequency range. Distortion was entirely
unacceptable.
After many years of research and engineering, EVENT has defi ed conventional audio
philosophy and created the Opal. Its woofer , tweeter, amplifi er and cabinet all feature
innovative and unique design and technology elements, combined to create one of
the fi nest studio monitoring system ever released.
The EX8 driver provides characteristics previously unheard of in any other 8”
speaker. It pr ovides a raw response of 30Hz-10KHz and a power handling of 1000 watts.
Its high-power neodymium motor offers 36mm of linear excursion which gives the
listener an extremely detailed and high level of high-speed bass.
The Opal’s patented X-Coil confi guration increases the EX8 driver speed and lowers
harmonic distortion by up to 18dB, which results in mid-range accuracy that truly surpasses even the fi nest three-way studio monitors. The EX8 proprietary cone material
provides extension and control to complete this revolutionary driver.
The Opal’s tweeter combines an ultra-light and rigid aluminiummagnesium alloy with a low resonance Sonomax surround to provide the Opal with
unbelievable high frequency defi nition while minimising any distortion.
in a fully rotatable waveguide to provide complete versatility in application.
It is mounted
Page 5
The Opal cabinet is moulded from aluminium to provide strength and minimise
resonance. It is curved in a combination of complex radii, completely minimising fl at or
cornered sections that can cause diffraction issues. A “no compromise” approach to
port design has resulted in front mounted variable impedance bass refl ex ports that
eliminate problems created by rear refl ection ports that rely on room acoustics, and
also air distortion artifacts found in conventional front ported systems. This gives the
Opal fast, deep and accurate bass response.
The Opal’s drive electronic system is purely high fi delity analogue, providing
750 watts of peak power in two-way confi guration and giving the Opal a transient
response and low distortion that surpasses the capabilities of any other monitoring
system.
All these elements combine to provide the Opal dynamic extended mid range and
powerful low end with seamless integration across the frequency range, and the
widest sweet spot of any system currently available.
The EVENT Opal is truly a revolution in studio monitoring.

Mains Input: Connect the mains supply here. Ensure that you use only the cable supplied or a genuine
EVENT replacement. Note that the amplifi er is not entirely disconnected from mains power unless this cable is
completely disconnected.
Mains Switch: Use the Mains Switch to turn the Opal on or off.
Module Dock: The Module Dock is a proprietary EVENT expansion Input/Output, allowing connection of the
Opal AES/EBU optional interface. If the module is connected, the expansion module status LED at the
bottom left of the front of the Opal will illuminate.
Balanced/Unbalanced Signal Input: The Opal allows for the input of a balanced or unbalanced line input.
The port accepts an XLR style cannon jack or a ¼” mono jack.
Please note that the Opal is fi xed to operate in the voltage range in the region that
it is sold in.
Page 11
status LEDs
The EVENT Opal is an extremely powerful studio monitoring tool, therefore care needs to be taken when
listening. Professional monitoring should ideally be performed between 85-95dB. While the Opal provides
ample headroom above these levels, extended listening can cause permanent hearing damage as well as over
excurt the EVENT EX8 driver.
The Opal features four status LEDs to indicate the speaker and amplifi er status. It is important to familiarise
yourself with the function of these LEDs as they will communicate the status of your speaker and the inputs.
Startup sequence : When the Opal is fi rst switched
on and is running a self diagnosis, the output will
be muted and the middle LED will illuminate white
for twelve seconds, then fl ash for ten seconds.
Following this the Opal will be ready for use.
Top light (green/yellow): The top light will fl ash
green in indication of the input signal level. In the
event that the signal begins to overload the amplifi er, the light will change to yellow.
This is intended as a warning only and it is up to
the listener to determine if the audio level needs
to be decreased.
Middle light (white/orange) : Following the
startup sequence, the middle light will only
illuminate white in the event of an
excessive input level. The Opal will
automatically attenuate output levels for ten
seconds to allow the operator time to
correct the source level.
The middle light will illuminate orange in the
event of excessive temperature, and the speaker output will automatically attenuate to allow the Opal to
reset. In this case it is important to lower the speaker temperature to reasonable level, after which the Opal
will automatically reset.
Bottom light (red) : The bottom light will only illuminate red in the event of a fault condition. In this case the
Opal requires factory service (see warranty information).
Operation of the AES/EBU expansion module status LED (blue) will depend on the actual module being
used. Consult the expansion module user guide for more information.

positioning your speakers
The EVENT Opal monitors are physically identical. When used in a stereo confi guration, there is no physical or
acoustic distinction between the left and right speakers. While we recommend mounting the Opal in vertical
orientation, it has been designed to allow horizontal alignment (see horizontal mounting).
For precise calibration within your monitoring environment please utilise the Event StudioEQ system,
available free of charge when you register your monitors online at www.eventelectronics.com.
sweet spot
Mount the speakers slightly inward, so that the driver components directly face the listening position. When
oriented this way, the listener is 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.
While not ideal, if you must mount the speakers substantially above or below ear level, you will also need to tilt
the cabinets downward or upward to keep the driver components directly facing you.
It is important to note that the listening space has a large effect on the performance of speakers,
particularly the low frequency response. It is best to try your monitors in a variety of positions to acheive
optimum results. Additionally the Opal’s in-built acoustic fi lters can be introduced (see front control panel).
Page 13
horizontal mounting
The EVENT Opal has been designed to overcome the performance issues exhibited in traditional monitoring
systems when mounting the speaker horizontally.
The key to this performance gain is the Opal’s rotatable high-frequency waveguide.
For more information on rotating the Opal waveguide please visit www.eventelectronics.com. Please note
that this operation should only be carried out by qualifi ed service personnel.
Note that when mounting the Opal horizontally, the tweeter should always be on the inside, as shown below.
The EVENT badge is also rotatable. To lift the badge from its magnetic mounting gently pry from the bottom
with a fl at screwdriver.
Please note that the supplied rubber plinth should always be used when mounting the speaker either
vertically or horizontally, to prevent any movement of the cabinet.
