This is the same
previous musical curve, this time limited by the Crest Factor system,
assessing the musical peaks from the musical program integration. Note in the curve enlargement (above, right) that
the music highest levels reach double the RMS power and keep dynamic and
pure, with no flattening whatever.
| See below the details about how to set the power of your Heavy-Duty: |
-
Connect the equipment
to the power line.
-
Turn on the power
switch on the front panel.
-
Set the gain controls
on the amplifier front panel to the closed position, which is the minimum
on the counterclockwise direction.
-
Attention: Do not place speakers on the amplifier
outputs, during the setting. This will not be necessary. Inject a 1-Volt
and 1-kHz signal into the R input of the ADL module to set the
power of the amplifier right channel. Now place a voltmeter on the
alternating current scale between the output terminals of the amplifier
R channel. After doing this, then turn the R gain control of
the amplifier front panel in order for the output voltage indicated on
the voltmeter to match the desired power. See the table below:

Now do the same as to the L channel. It is ready.
Note: For an increased safety, we can lock these front panel positions with a locking manufactured by us. Order over the telephone (011)-5531-6736, with Edgar.
When we use speakers in parallel on the amplifier output, the amplifier output voltage should be set based on the individual power in Watts RMS of each speaker we are using, and according to the above Power / Voltages table.
Example.
On the amplifier output there is a single 250-watt speaker. We should seek in the table the voltage corresponding to 250 W, which is 44.7 Volts, and do the setting.
.
In another example, if we are to place two 250-W speakers in parallel, or even 3 or 4 speakers in parallel, we must seek that same value corresponding to only one of the speakers, that is, 250 W / 44.7 V, and set the amplifier output to the same 44.7 Volt value.
.
The amplifier will automatically send a maximum 250 Watts to each one of the speakers.
.
The total output power will vary according to the number of speakers added, and it will be 500 Watts in case of two speakers, 750 Watts for three speakers, or 1000 Watts if we add maximum 4 speakers. In all instances, a maximum 250 Watts will be ensured per channel.

On the Plug&Play Studio R
modules with crossover, the Crest Factor limiter can be set by the rotary control located to the left on the module back panel, with graduation in %. For other details, check the owner's manual of each module.
