Multi-Function - Ecler MPA4-150R Bedienungsanleitung

3.4. Multi-function

Depending on the input switches on the MPA R (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
located on the rear panel, four different amplification configurations can be achieved:
MPA4-150R
- 4 mono amplifiers with following possibilities:
4 different mono inputs
1 common mono input for all
1 common stereo input for all
- 2 stereo amplifiers with following possibilities:
2 different stereo inputs
1 single stereo input for both
- 2 bridged amplifiers with following possibilities:
2 different mono inputs
1 common mono input
1 common stereo input
- Combinations between mono, stereo and bridged - Combinations between mono, stereo and bridged
On the rear panel you can also activate the high-pass and low-pass filters:
High-pass filter ON/OFF switch (27, 31). The cut-off frequency lies at 160Hz for amplifiers 3 and
4 (5 and 6) simultaneously or when operating in bridged mode. This filter cuts out all frequency
components under 160Hz and passes the rest, being specially suited for connecting the mid-range and
high frequency speakers.
Low-pass filter ON/OFF (23). Filter with 160Hz cut off frequency for amplifiers 1 and 2 together or
when working in bridge mode, which eliminates audio signals with frequencies higher than 160Hz and
lets through those signals with frequencies lower than 160Hz.
Combining one bridged amplifier with switched on low-pass filter together with a stereo amplifier
with switched on high-pass filter turns your multichannel power amplifier into an ideal equipment for
clubs and other locations with a subwoofer, mid-range speakers and tweeters.
