2.3.1 Clip limiter
When the input signal connected to your amp is too high, you end up with a
distorted output signal. To prevent this, both channels of your EUROPOWER
feature a clip limiter that can be engaged or disengaged selectively. The limiters
automatically recognize distortion and lower amplification until distortion is
reduced to a tolerable level. To preserve the dynamic characteristics of the signal
when low distortion levels are occurring, the clip limiters function with moderate
suppression. Use switches 1 (ch. 1) and 10 (ch. 2) to activate the clip limiters.
When using broadband loudspeaker systems, the clip limiter reduces high
frequency distortions which occur when an amplifier is overloaded. The drivers
are thus protected from being damaged.
2.3.2 Input filter
The LF (high-pass) filter removes frequencies below 30 and 50 Hz respectively.
The reproduction of the signal's bass portion is thus optimized, since ultra-low,
distracting frequencies are eliminated, and more power is available for the
reproduction of the wanted segment of the signal. Engaging and disengaging
the filters is done by using the switches 3 (ch. 1) and 8 (ch. 2). Switches 2 (ch. 1)
and 9 (ch. 2) determine the cut-off frequency. As long as the filter is disengaged,
frequencies below 5 Hz are cut to prevent damage.
You should set up the filters so they best suit the frequency response of your
speakers, since some speakers (e.g. bass reflex speakers) are particularly sensitive
to over-excursion below the listed frequency range.
