1. DESIGN FEATURES
■
CAR AUDIO AMPLIFIER
: This EMPHASER amplifier allows the cross-over controlled amplifica-
tion of satellite speaker systems, kickwoofer or subwoofer systems
■
DASH-MOUNT REMOTE LOWPASS LEVEL CONTROL
: This amplifier comes complete with
a compact remote "Lowpass-Level" control unit, which can be conveniently mounted on or under the
dashboard of your car. This control device allows the individual level adjustment of the volume level
(applicable for the lowpass operated channels)
■
MOSFET POWER SUPPLY
: This EMPHASER amplifier features a beefy MOS-FET power supply,
to boast very high power output. The EA4150 is equipped with two independent power supplies, to
prevent cross interference of the channel pairs 1/2-CH and 3/4-CH
■
1 OHM IMPEDANCE LOAD STABILITY
: The channels of this amplifier are stable into 1 ohm
loads. Furthermore, the output stage layout provides a very high damping factor and thus, the ampli-
fier will exhibit full control over the connected speaker system(s)
■
INTEGRATED ELECTRONIC FREQUENCY FILTERING CONTROLS
: The internal crossover
section features independently selectable highpass, lowpass or bandpass filtering, as well as fulllran-
ge loop through. All internal active filters feature crossover slope rates of 12 dB/octave
■
UNCOMPROMISING DESIGN AND CONSTRUCTION
: Only best electrical and electronic
components found their way into this amplifier, for example double-sided glass-fiber epoxy circuit
boards equipped with high current output devices. The power input side features molded 35mm
2
ter-
minals for full unrestricted current flow
■
ADVANCED PROTECTION CIRCUITRY
: The protection circuitry safe-guards the amplifier from
short-circuits at the speaker outputs, DC offset voltage at the outputs and overheating of power elec-
tronics
■
STATUS AND PROTECTION LED'S
: A green and a red LED enable you to easily monitor the
operating status of your EMPHASER amplifier. The LED's are signaling normal operation and pro-
blems, such as short-circuits, electrical or thermal overload and DC voltage at the speaker outputs
■
ADJUSTABLE INPUT SENSITIVITY
: Each RCA line-input pair accepts input voltages from
200mV to 9V, providing a good match to the line-output levels of almost any head-unit on the market
■
EXTERNAL FUSES
: The input side-panel of this amplifier is equipped with Maxi type fuse holders,
for a fast and convenient exchange of blown fuses
■
INTERNAL FAN
: This amplifier features advanced heat management by a temperature controlled
internal fan
