2-channel mode (stereo) 2.3.3
Both channels of your amp function independently from
one another in this operating mode, and each has its own
input signal. Two independent speakers are connected at the
outputs. To activate this operating mode, please set the MODE
SWITCHES 4 and 5 to “STEREO”.
When running the unit in two-channel mode, the switches ◊
for mono-bridged mode must be disengaged (dip switches
6 and 7 in left position).
Parallel mode 2.3.4
Running in parallel mode enables you to feed a signal via one
of the inputs into both outputs. Each channel drives its own
loudspeaker with independent amplification, filter and limit
characteristics. To link the inputs, set the MODE SWITCHES
4 and 5 to “PARALLEL INPUTS”.
Mono-bridged mode switches must be disengaged when ◊
running in parallel mode.
With inputs set to parallel, you can use the remaining input
connectors to feed the signal into additional amplifiers.
This means that the channel 2 inputs function as outputs.
The parallel mode is well-suited for applications in which
driving two speakers with the same signal but with separate
amplification, filter and limiter settings is desired.
Mono-bridged mode 2.3.5
This operating mode enables you to add up the respective
voltage of both channels and use it to drive a single loudspeaker.
The voltage is therefore doubled, the peak power is quadrupled,
and program power is roughly three times as high as that of the
individual channels. The input, output, gain, filter and limiter
controls belonging to channel 1 are used when running in mono-
bridged mode. The controls belonging to channel 2 are not used.
To prevent signal cancellation due to internal phase inversion,
the GAIN control belonging to channel 2 must be turned to its
left-most position.
Use this operating mode to route the power from both channels
to a single 8-Ohm or 4-Ohm load. To do so, set up the switches
6 and 7 to “BRIDGE MODE ON”. To use the binding posts as
your output, you MUST use the two middle posts only.
The mono-bridged mode puts added demands on amplifier ◊
and speakers. Excessive distortion may occasionally com-
pletely mute the amp’s outputs as well as cause permanent
damage to the speakers. Please assure that your speakers
(minimal impedance 4 Ohms) as well as the cables used can
handle the extra power generated in this mode.
Applications 3.
Running EUROPOWER amplifiers in conjunction with ◊
8-Ohm speakers with a power rating of at least
2 x 400 Watts (EP2000) and 2 x 750 Watts (EP4000) is
recommended to assure optimal operation.
Differences between 2-channel, 3.1
parallel and mono-bridged operating
modes
2-channel mode is the most common operating mode of
amplifiers. Both channels operate fully independently from one
another. There is always a separate input signal as well as a
separate output signal.
