Acumen 6A / Acumen 8A
English
INTRODUCTION
Congratulations on your purchase of another great
product from Phonic. The bi-amplified Acumen 6A and
Acumen 8A are two-way active monitors designed for
high output and unsurpassed clarity.
The Acumen 6A offers a 6” woofer and 82 Watts
of power while the Acumen 8A is an 8” model with
98 Watts of power. The paper cone woofers offer
extended low frequency response and higher output
level.
The Acumen’s compact size, excellent dispersion
and precise stereo imaging make it 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 balance even in
difficult acoustic environments.

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 1.7kHz.
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
overload protection. Variable input sensitivity allows
for accurate level matching to the mixing console.
MOUNTING THE MONITOR
Vertical / Horizontal Mounting
The speakers are normally delivered for vertical
mounting. Designed for near field monitoring,
this studio monitor requires shorter distance than
traditional monitors from its location to your ears,
which means the reverberation time and general
acoustics of the listening room are less critical. Hard
surfaces will, however, reflect the higher frequencies,
therefore try to avoid putting this monitor close to
side walls.
The control surface of your mixing console may
also pose a problem. To minimize control surface
reflections, position your monitor as shown in the
figure below, using the meter bridge or rear panel to
block sound from both drivers reaching the control
surface. Make sure that there is nothing between
your ears and the speakers.
If your console has no meter bridge, try positioning
the monitor higher or further behind the desk. Active
series is designed to be used in both the upright and
horizontal position. If you want to place two Active
series horizontally, it is recommended you put the
HF drivers on the outer edge. The low frequencies
of this unit will generally sound better if the cabinet
is against a wall. If possible, provide a rigid surface
(eg. shelf) that is separate from the mixing console
and other equipment. The speakers should roughly
form a 60 degree angle at the listening position, and
should be angled towards the listener.
Console Top Mounting
If the active studio monitor series are used for
console top mounting, it is recommended not to
mount the speakers directly on the console; instead,
position the speaker slightly behind the console by
using floor stand or wall mount behind the console.
This prevents the reflection from the console surface
from coloring the sound.
