Description With its 4 separate output
stages, this newly developed 19˝ 4-channel power amplifier provides different
operating modes and a wide range of connection options.
Features
<li>SOFT START The amplifier features a speaker turn-on/off delay to
protect the loudspeakers and to avoid pops associated with turning power on or
off. </li> <li>PROTECTION CIRCUITS The JFX-425 has protection
circuits against short circuit, overheating, inductive load, etc. </li>
<li>LIMITER The limiter serves as an overload protection for the
loudspeakers and can be switched separately for each channel. </li>
<li>PERFECT COOLING The amplifier is equipped with a quiet running cooling
fan, which, together with the vents in the housing, provides excellent cooling.
</li> <li>MODERN DESIGN The JFX-425 power amplifier has a modern,
functional and economic 19˝ design (2 RU). It is suitable for demanding
applications and gives great performance, even when operating at \"full load\".
</li> <li>INFORMATIVE DISPLAY The front panel of this amplifier has
been designed in such a way that the user constantly gets all important
information on the current operating status, e.g. through indication of
protective functions, active clipping, power on, temperature, etc. </li>
<li>X-OVER/3D FUNCTION Different operating modes are available to the user
including: - 4-channel mono ( 4 x 250 W ) - 2-channel stereo linear (internal
crossover network deactivated) - 2-channel stereo operation with active
crossover network (50Hz - 2,5 KHz) - 2-channel stereo operation with crossover
network and mono bass </li> <li>AKTIVE CLIPPING The amplifier
features a special ACTIVE CLIPPING function across the entire frequency range of
20 Hz - 20 kHz. The input and output signals are constantly compared, and
deviations that exceed a certain value, e.g. 0.5%, are indicated by the signal
LED
