EZ-A SERIES
FEATURES
The EZ-12A and EZ-15A have been developed to answer a specific need for entertainers,
presenters and performers who demand high powered PA systems but in any location.
Powered by an internal battery or by a versatile 100v-240v mains input, these systems
can go anywhere. With an internal MP3 player, wireless mic input, Bluetooth connectivity
and even standard analogue connectors, the new EZ series are ready to accept inputs
from anywhere.
Portability was the design priority so the EZ’s have 2 integral wheels and a practical pull
up handle. This makes transportation painless and straight forward.
The rear panel controls are user-friendly. These give easy access to input levels, internal
echo processing, the 5-Band graphic EQ and a very handy dedicated control knob for the
MP3 player volume. The simple controls allow inexperienced users to get a professional
sound.
The new EZ-12A and EZ-15A are supplied with 2 high quality handheld wireless
microphones. This means that the system can be up and running in seconds - without the
need of any additional hardware.
A handy remote control gives access to the transport controls of the internal MP3 player
section.
The electronics of EZ are versatile and comprehensive, however the transducers and
amplification components are also of the highest quality.
EZ-12A delivers up to 115dB Max SPL @ 1m while the larger EZ-15A reaches 118dB Max
SPL @ 1m. This power ensures that music, speech or both are clearly heard wherever the
EZ is used.

IMPORTANT WARNINGS & SAFETY INSTRUCTIONS
UNDER NO CIRCUMSTANCES ATTEMPT TO RIG, SUSPEND OR OTHERWISE MOUNT THESE
SPEAKERS UNLESS YOU ARE FULLY QUALIFIED AND CERTIFIED TO DO SO BY RELEVANT
LOCAL, STATE AND NATIONAL AUTHORITIES. ALL RELEVANT SAFETY REGULATIONS MUST
BE FOLLOWED. IF YOU ARE NOT PROPERLY QUALIFIED OR DO NOT KNOW OF PERTINENT
REGULATIONS, CONSULT QUALIFIED PERSONNEL FOR ADVICE.
1. READ ALL INSTRUCTIONS – carefully and become familiar with the features and
func tions of these products before operating them.
2. RETAIN THESE INSTRUCTIONS – for future reference.
3. COMPLY WITH ALL WARNINGS – All warnings and instructions for this product
should be adhered to.
4. USE WITH AMPLIFIERS – In order to avoid damage to drivers and other
equipment, it is advisable to establish and follow a routine for powering up and
powering down a sound system. With all system components connected, turn
on source equipment (mixers, signal processors, record and playback units, etc.)
BEFORE powering up amplifiers. Transient voltages from powering up source
equipment can damage speakers if amplifiers are already turned on. Make sure
that amplifier volumes are set to their minimum settings and power up any
system amplifiers LAST. It is recommended that all system components be
allowed to stabilize for several seconds before any source signals are
introduced or level setting adjustments are made. Similarly, when shutting
systems down, turn all amplifiers off first, before powering down any other
system components.
5. CABLES – Do not use shielded or microphone cables for connection between
amplifiers and speakers. Use only approved speaker cables with proper
connectors.
6. CAUTION – These professional loudspeaker systems are capable of generating
very high sound pressure levels. Use care with placement and operation to
avoid exposure to excessive volume levels. Permanent hearing damage can
result when operated to extreme levels.
7. SERVICE – There are no user serviceable parts inside this product. Users should
not attempt to service this product. Warranty nullification could result if this is
attempted.
8. RIGGING - SUSPENDING - MOUNTING - Rigging suspending or mounting of
speaker systems can expose members of the public to serious health risks and
even death.
