4 - CONNECTION TO THE MAINS

First, it is essential to ensure that the main voltage corresponds to the
apparatus voltage. It is not advisable to connect and disconnect the mains wire
without first making sure that the switch is in its OFF position.
The amplifier is equipped with an Inrush current limiter circuit, which avoids current
excess when powering up. In addition to that, a breaker switch located close to the
IEC socket protects the amplifier when the average current consumption is out of the
specified range.
CAUTION: the connection to any other voltage
different from the one specified can damage the
amplifier immediately.
5 - CONNECTION OF THE LOUDSPEAKERS
The loudspeaker system should be connected to the Speakon or Terminal
connectors ensuring that the polarity is correct. It is very important to use a cable
fitting to the power of the amplifier in order to maintain the high damping factor these
units provide. As a general guideline, we offer a table of the minimum cross section
values according to the distance:
- Up to 20m in length: cross section of minimum 2.5mm
- From that length on, increase the section to 4 mm
These cross-sections correspond to
impedance of 8 Ohms; they should
be increased for impedance of 4
Ohms. If you use very low loads (2
Ohm) the cross section has a very
important role in the sound quality.
There are two speaker outputs: CH A and CH B both fitted with Speakon sockets and
Terminal type (binding posts) connectors.
The Speakon connector (not included) has 4 terminal poles labeled as +1, -1, +2 and
-2. Each pole can fit a maximum wire section of 4mm
applications this connection may also be soldered to guarantee better contact.
The Binding Posts are marked with Red for the Positive Pole, and Black for the
Negative Pole. They accept direct cable connection up to 8mm
