6.6 Output connections
The output section on the rear panel features Euroblock connectors (15, 16).
In STEREO mode, each channel takes the signal from its corresponding input (OUTPUT
CH1 from INPUT CH1, OUTPUT CH2 from INPUT CH2 etc.). In MONO/BRIDGE mode, the
signal is taken from the odd input only.
To operate the amplifier in bridged mode, the "ST/MONO" (14) switch shall be on
MONO/BRIDGE. The input signal connection is performed using the odd channel
connector and the speaker signal comes out of the BRIDGE labeled terminals on the
Euroblock output connector. Optionally you can connect the other two output terminals
to each other, in order to improve the distortion value. They have to be connected with a
short cable.
The connection cable that joins the amplifiers outputs and the loudspeakers must be of
good quality, sufficient section and as short as possible. This is most important when the
distances to cover are long ones.
7. OPERATION AND USAGE
7.1. Start up
The red "PROT" LEDs (7) light up when you turn on the power switch (11). A second after
all voltages have been stabilized and the amplifier is operating, "PROT" indicators turn off.
In a complete audio installation, it is important to power on the equipment according to the
following sequence: sound sources (microphones, music players, etc.), mixers, equalizers,
active filters and power amplifiers. To power off, follow the reverse sequence.
7.2. Input attenuators
This consists of rotary potentiometers, situated on the front panel (5, 6).
These attenuators allow connecting the amplifier to different types of mixers and
processors, independent level control and connection of speakers that can't handle the
wattage supplied by the output stage at full power, without risking damage if the volume
of the preamplifier-mixer is set too high.
