3.3. 'Earth Link' switch

The Earth Link or Ground Link switch (9) prevents possible ground loops when various
machines in the same chain are connected to earth. This switch makes possible to disconnect the
electrical ground from the mechanical ground. Whenever hum arises, alternatively switch the
earth link switches of the amplifier and others components of the audio chain.

3.4. Input signal connections

The signal input connectors are of XLR-3 type (1 3), electronically balanced. The pin
assignement is as follows:
1.- GROUND
2.- PHASE (signal in phase with the output)
3.- NON PHASE (signal in opposite phase with the output)
The input connections for a balanced or unbalanced sound signal are as follows:
The 'STACKING OUT' outputs (12) are in parallel with the inputs and are used to supply the
same input signal to other amplifiers or sound systems.The input impedance is 47K Ω (balanced)
with a nominal input sensitivity of 1V (0dBV). This impedance makes possible to parallel several
amplifiers without loosing audio quality.
The input circuit has an electronic protection against overloads of 100Vpp(permanent) and
450Vpp (short moments). There is an RLC radiofrequency filter that avoids possible
intermodulations and also protects the treble loudspeakers. The rising time of the input signal has
been optimized for a very low TIM.
