SAFETY INSTRUCTIONS
1. Read all instructions carefully before using your GWA Speakers.
2. Keep this safety and instruction flier for future reference.
3. Ensure you follow all instructions carefully.
4. When used in conjunction with Amplifiers or Powered Mixers
ensure you follow the correct procedures in the set up and
turning on and off of audio equipment. It is advisable, when an
entire sound system is set up, that the power amplifier or
powered mixer that you are using is turned on last (ie. That any
source equipment, such as guitars, tape decks, etcetera, are
turned on first). After all source equipment is turned on and have
stabilized, ensure the power amp or powered mixer’s level
control is set to a minimal level and then activate, after which the
level control can be set to a reasonable level. This should be
done in reverse when shutting down: turn off the power amp or
powered mixer first, then turn off all other devices. However
many professional amplifiers feature delayed on/off circuits that
can perform this automatically.
5. Warning
– The GWA Speakers generate extremely high sound
pressure levels. Ensure you take care in the placement and
operation to avoid exposure to extremely high sound levels, to
reduce to risk of causing permanent hearing damage.
6. Cables
– Under no circumstances should you use shielded or
microphone cables for connecting speakers to amplifiers. These
cables are not heavy enough to be able to handle the amplifier
load and could cause irreversible damage to your system.
7. Mounting
– The suspending, rigging and mounting of the GWA
Speakers can cause members of the public to be exposed to
serious health risk, as well as the possibility of death. If you are
NOT fully qualified and certified to mount these speakers by
relevant local, state, or national authorities, do not under any
circumstances try to rig, suspend or mount this system. All
relevant safety regulations must be followed. If you are not
completely qualified or do not know of said regulations, ensure
you consult qualified personnel for assistance.
8. Servicing
– Do not under any circumstances try to service this
product by yourself. If servicing is required, contact your local
service center.
INTRODUCTION
The GWA represents the best of Ph
onic’s speaker revolution. The
GWA
’s Curvature Line Array Loudspeaker System enhances audio
dispersion and works with internal bracing to increase structural
strength and to minimize diffraction.
Phonic’s proprietary designed
horn, developed using computer-aided modeling, offers extremely
balanced sound projection and low distortion even at high volumes.
Our development team also crafted compression tweeters and long-
throw composite woofers to ensure the GWA
’s sound quality
matches its stunning cosmetics. The durability of the GWA series is
unmatched. The GWA is protected by multi-layer scratchproof paint.
The GWA series is the most versatile in its class with heavy duty
pole mounts. With an unsurpassed audio response, sensational
power handling, and fantastic flexibility, the GWA establishes a new
benchmark.

Equalization
The GWA speakers are design to perfectly reproduce all audio
signals as sent by your amplifier or powered mixer. As such,
your equalization efforts do not need to take speaker response
into account, rather your main concentration should be on the
acoustics of the venue. If equalization is applied, it should be
done so with the utmost of case. Applying overly harsh
equalization can be detrimental to your overall sound.
Connection
The GWA speakers are equipped with professional Speakon
speaker connectors on the rear of the speaker. The input
connectors on each unit should be connected to an appropriate
output device such as a power amplifier or powered mixer. The
Speakon connectors do not need to be soldered into place;
rather they are pushed into the socket and turned clockwise to
lock. Once all equipment is turned off, twist the connector
counter-clockwise to disconnect. The output connector can be
used to run two (or more) speakers in parallel.

Pin - = - on amplifier
Impedances
The nominal impedance of the GWA speakers i
s 8Ω. This means
that a single GWA speaker can be used with an amplifier channel
that can run down to 8Ω. Similarly, two speakers can be used with
an amplifier that can run at 4Ω per channel and four speakers can
be used with an amplifier that can run at i
mpedances of 2Ω (check
the amplifier’s recommended operation before doing so).
Operation
When making a connection, be sure to turn off the amplifier that
you are connecting to. Use professional Speakon connectors
and cables only. Once connections are made, turn the amplifier
on with all channels set to the zero position. Be sure not to drive
the amplifier to the point of overload or clipping for any length of
time as to ensure the integrity of the speaker’s voice coil.
