CHOOSING POWER AMPLIFICATION
Selecting a power amplifier for an R2 is straightforward. See page 14 on “High Pass Filter” and page 22 on
“Limiting” for additional consideration in selecting an amplifier.
POWER RATING
The R2s are rated at 400W RMS and 1000W program power. The recommended amplifier is one with a rated
RMS output from 800W to 1200W at 4 ohms. If two R2s are to be connected to one amplifier channel, use an
amplifier with a rated RMS output from 1700W to 2300W at 2 ohms.
Using an amplifier of less power than recommended can result in amplifier clipping that can quickly damage the
drivers. The built-in DYNA-TECH™ protection circuitry cannot detect clipping nor will it function properly when
less than the recommended power is used.
Using an amplifier of more power than recommended can result in overdriving the loudspeaker with the potential
for damaging the drivers and/or the protection circuitry.
DYNA-TECH™ PROTECTION CIRCUITRY
All R2s are equipped with DYNA-TECH protection circuitry built into the crossover. It is designed to provide a
certain measure of protection against excessive current being delivered to the individual drivers and to the over-
all system. There is no external indication of when the protection circuitry is active. For this reason it is strongly
recommended as an additional precaution that an external electronic limiter be used prior to the amplifier (See
“Operating Precautions”, page 22).
