5.7 Connecting speakers
Speaker connections are made via the two Neutrik NL4FC Speakon
connectors (1). These connectors meet the EC safety requirements. They
are wired as follows:
Pin -1 Speaker ground.
Pin +1 Speaker positive.
Pin -2 No connection.
Pin +2 No connection.
Figure 9. Speakon connector
Please note that this is the standard wiring convention for Speakon
connectors adopted worldwide.
Never connect either output terminal to ground or to some other
output or input terminal (see warning on page 2). For normal two-
channel operation, connect each speaker load across the outputs positive
and ground terminals. Pay attention to speaker polarity; loudspeakers
connected out of polarity can degrade sound quality.
Keep the speaker cables as short as possible and use a good quality
stranded speaker cable. Do not use shielded wire, such as microphone or
guitar cable. Remember that the speaker cable robs the power of the
amplifiers in two ways: It increases the load impedance and introduces
resistive power losses.
5.8 Impedance matching (MLS switch)
The MLS switch is located on the rear panel with an LED showing the
switch depressed and in the 2 ohms position.
The MLS ( Minimum load select ) switch offers an impedance matching, so
you can drive the MA1.6 in 2 ohms without increased heat losses. Table 2
shows the possible combinations:
Table 2.
The way to find the best MLS™ position for your application is by
experimentation. The amplifier is very well protected (even down to 0.3
ohms), but where speed is of the essence, stick to the fixed positions.
