[. . . ] (22. 7 kg) Features: · Two-way, full range/biampable PA enclosure · Sound GuardTM HF driver protection circuit · RXTM22 driver with a 2" titanium diaphragm coupled to a CH® 3 90° X 45° constant-directivity horn · 12" BWX Black Widow® with Kevlar® cone and field-replaceable basket · SPTM X series cabinet with integral stand adapter · Neutrik® biamp jack · 30o or 45o baffle angle SP 112 MX exceeds a predetermined threshold, the Sound Guard III circuit is engaged. The effect that this has is to subtly decrease the signal level going to the RX22 so that it will not be damaged due to longterm overpowering. Short duration transients will not be attenuated by Sound Guard III and have the possibility to damage the RX22. [. . . ] Short duration transients will not be attenuated by Sound Guard III and have the possibility to damage the RX22. The Sound Guard III circuit is a dynamic circuit that will attenuate the signal more the larger the signal is, very similar to a compressor. This is accomplished through the use of a specially selected, dynamically resistive light bulb. If the bulb in your Sound Guard III should ever burn out a replacement may be obtained from an Authorized Peavey Service Center. However, if a Peavey replacement bulb is not readily available, a Sylvannia SK3 bulb may be located at various loudspeaker or electronics parts stores. Power Handling There are many different approaches to power handling ratings. Peavey rates this loudspeaker system's power handling using a full-range form of the AES Standard 2-1984. Using audio band 20 Hz to 20 kHz pink noise with peaks of four times the RMS level, this strenuous test signal assures the user that every portion of this system can withstand today's high technology music. This rating is contingent upon having a minimum of 3 dB of amplifier headroom available. Harmonic Distortion Second and third harmonic distortions vs. Sound Guard III is the redesign of Peavey's proprietary circuit for high frequency driver protection for the new RX22 compression driver. This is an integral part of the crossover for the CYBERBASS 5. The input signal is routed through the Sound Guard III circuit in both fullrange and biamp modes of operation.
