5. INSTALLATION
5.1 Placement, mounting, cooling
All eHSA2-250, 2-500, 4-250 y 4-500 amplifiers are presented in standard 19” rack
format and are 2 units high.
It is important that the amplifier, as a heat source, is not placed next to other
equipment nor exposed to high temperatures.
It is also advisable not to rack the power amplifiers under other devices, but on top
of these, that is to say as high as possible toward the top of the rack cabinet.
5.2 Mains connection
The eHSA amplifiers are powered by 115 to 230VAC, 50/60Hz. (by voltage selector
on the rear panel, MAINS SELECTOR)
The mains cables must not be near the shielded cables carrying the audio signal, as
this could cause humming.
In order to protect the power amplifier from eventual power consumption
overloads, it is protected by a set of fuses. Should a fuse blow, it must be replaced
immediately by one with identical rating. If it blows again please contact our
Technical Service Department.
NEVER REPLACE THE FUSE WITH ANOTHER ONE WITH
A HIGHER VALUE
.
CAUTION:
Fuse substitutions have to be performed by a qualified technician.
5.3 Input signal connections
The signal input connectors are of EUROBLOCK and electronically balanced. The pin
assignment is as follows:

Hot or direct signal > +

Cold or phase inverted signal > -

Ground > Ground
For unbalanced connections, ground the negative terminal on the Euroblock.
In balanced mode, the input impedance is greater than 20k

(10k

unbalanced),
allowing you to connect a large number of stages in parallel without compromising
the sound quality.
