Introduction; Features; Installation - Phonic P5A Manual Del Usuario

INTRODUCTION

The bi-amplified P5A/6A/8A are two-way active monitoring speak-
ers designed for high output, low coloration and broad bandwidth.
P5A is 5" 2-way; P6A is 61/4" 2-way, P8A is 83/4" 2-way. Bigger
number means bigger power as well as bigger woofer, which of-
fers extended low frequency response and higher output level.
Due to its compact size, integrated construction, excellent disper-
sion and precise stereo imaging, this speaker system is ideal for
near field monitoring, mobile vans, broadcast, TV control rooms
and home studios.
Designed as an active speaker, this unit contains drivers, power
amplifiers, active crossover filtering and protection circuitry. The
directivity control system used provides excellent frequency bal-
ance even in difficult acoustic environments.
SOFT DOME WITH SOUND GUIDING HORN
This horn is designed to provide better sound directivity for the
listener(s). With its smooth surface and well-spread angle, the
sound produced from the tweeter can be easily forwarded to the
listener(s).
DRIVERS
The bass frequency is reproduced by a 5-inch, 61/4"-inch, and
83/4" -inch woofer respectively. P5A, P6A, and P8A all use a 25mm
(1 inch) soft dome tweeter, with pure piston behavior up to 20KHz.
The uniform dispersion control is achieved with the directivity
control system. This has also resulted in perfect phase and delay
uniformity at thecrossover frequency. Both drivers in PSeries Ac-
tive Version are magnetically shielded. Please feel free to place
this unit next to your PC, laptop, or any other electronic devices.
CROSSOVER
The active crossover network consists of two parallel band pass
filters. Acoustically the filters are complementary and the slopes
are 24dB/ octave. The crossover frequency is set to 1.8KHz. By
use of active crossover controls (Low Match, Room Compensation,
and High Match, which will be introduced on page 6), this speaker
may be exactly matched to any application.
AMPLIFIERS
The amplifier unit is mounted to the rear panel of the speaker
with damping material, to ensure rattle free operation and long
term reliability. The unit incorporates special protection circuitry
as well, for driver overload protection and amplifier thermal over-
load protection. Variable input sensitivity allows for accurate level
matching to the mixing console.

INSTALLATION

Each active studio monitor is supplied with an integrated amplifier
unit, a mains cable and an operating manual. Once unpacked,
place the loudspeaker in its required listening axis. Before con-
necting up, ensure that the mains switch is off. Audio input is
made via a balanced (XLR) and 1/4" TRS phone jacks, which are
in paralell. But unbalanced leads may be used as long as pin 3 is
grounded to pin 1 of the XLR, or linking Ring to sleeve of the 1/4"
TRS phone jack. Once connection has been made, the speakers
are ready to be powered-up. Before turning the unit on, make sure
the mains needed is identical with the AC outlet.
SETTING THE INPUT SENSITIVITY
Adjustment of the input sensitivity of each speaker can be made
to match that of the mixing console or other source, by using the
input sensitivity control on the rear panel. The manufacturer default
setting for this control is -6dBu (fully clockwise).
SETTING TONE CONTROL
The acoustic response of the system may also have to be adjusted
to match the acoustic environment. The adjustment is done by
setting the tone control switches on the control panel of the ampli-
fier. Phonic' s default settings for these controls are to give a flat
anechoic response. Set switch to the desired position to select
response curve needed.
