9.-
100 V INPUT
: 100 V line signal input. The 100 V line inputs have priority through signal level which
attenuates the level of the rest of the inputs.
10.-
LINE OUT
: aux line output. Signal output for recording, mixer, power amp, etc., 2 x RCA connectors.
11.-
AUX
: aux input. Signal source input, allowing the connection of audio sources via 2 x RCA connectors.
12.-
INPUT 1-2
: microphone/line inputs that use an XLR connector, accepting balanced and unbalanced 30-
600 Ω microphone signals and balanced electret condenser microphones that require 24 V phantom
power, present in pins 2 and 3 on the XLR connector. They accept line level, balanced or unbalanced
signals equally whether they come from mixers or audio players, etc.
Select the appropriate position using the switch, making sure the volume controls are at their minimum
to avoid making noise.
Microphone 1 and 2 inputs have priority depending on the signal level, which attenuates the level of the
rest of the inputs to give preference to paging.
CONNECTION
- Make the connetions with the amplifier and all the components of the installation switched off and
disconnected from the mains.
- Connect the audio equipment or the required microphones to the corresponding inputs. If a dynamic
microphone is connected to input 1 or 2, place the selector in the MIC position. If a condenser microphone
is connected, place the selector in the PHANTOM 24 V position.
If a line level source is connected to input 1 or 2, place the selector in the LINE position.
- If you wish, a line level source can be connected to the aux input designed for this purpose, on the front
panel as well as on the rear panel.
- If the low impedance output is used, the loudspeakers must be connected in a series/parallel circuit so
that the loudspeaker load impedance is the same as the amplifier output impedance and the power
supplied by the amplifier does not exceed that withstood by the loudspeakers.
- If the 100 or 70 V high impedance output is used, all the loudspeakers must be connected in parallel and
the sum of the power of all the speakers must not exceed the power supplied by the amplifier.
- Power the amplifier mod.

using the AC mains connection.
- Once the connections have been made according to your needs, connect the equipment to the mains and
switch it on. After use, do not forget to switch it off and disconnect the equipment from the mains.
