OUTPUTS
Channel A and Channel B speaker outputs are via Neutrik Speakon connectors. 4 poles are used. 2-pole
(NL2FC) or 4-pole (NL4FC) connectors can be used.
Terminations are as follows :- Pin +1, +2 = +ve
Pin -1, -2 = -ve
NOTE: 1. Negative (-ve) output terminals from Channel A & B must not be joined together, since they
are not both at 0V.
Because the currents involved are very high, the speaker cables should conform to the following
minimum requirements, otherwise the losses will cause the cables to get hot and audio power
will be reduced:
E90 - 25A into 4 ohm speaker loads.
Operation
SWITCHING ON
At ‘switch-on’ the protection circuit will initially activate whilst the circuits stabilise. Assuming no faults
are detected after a few seconds, only the ‘POWER’ LED (and ‘SIGNAL’ indicators if signal is applied) will
illuminate.
PANEL CONTROLS AND INDICATORS
Level controls
These are analogue controls allowing precise level settings. Note that in ‘CH LINK’ mode only ‘channel
A’ control is active.
Signal Indicators (3 Green LEDs)
These are active from a minimum output level of approximately 10 Watts and are only an indication of
signal level.
-3dB Indicators (yellow LED)
These are active when the signal is 3dB below the limiting level.
Limiters (Red LED)
The E Series amplifiers incorporate signal limiters, which are preset to prevent clipping with high levels
of drive. The red LED’s on the front panel illuminate to indicate operation of the limiters.
PRC Indicators
(green LED)
These indicate when the PRC circuit for that specific channel has been selected with the rear panel
switches.
