The UPM-1 operates as a system
with the P-1A Control Electronics Unit. Optimized for the UPM-1 and pre-aligned at the factory, the P-1A contains frequency response and phase response alignment
circuitry, and Meyer Sound's exclusive SpeakerSense? driver protection circuitry, incorporating both peak and RMS signal
limiting. SpeakerSense protects the UPM-1 loudspeaker components from damage due
to overheating under high power conditions. This unique circuit continuously Monitors the power applied to the UPM-1 drivers, and limits the signal output when
the safe operating limits of the drivers are exceeded. Until the onset of overload, the SpeakerSense circuitry has no effect on the signal.
Six stages of Meyer's exclusive complementary phase equalization in the P-1A
Control Electronics Unit give the UPM-1 flat frequency response with outstanding phase characteristics.
A single-channel device operating at line level, the P-1A is the final component in the signal chain before the amplifier.
Meyer Sound
Established by John and Helen Meyer in 1979, Meyer Sound has been at the forefront of innovation in audio engineering for over two decades. From the outset, Meyer Sound looked beyond loudspeaker cabinet design to create totally integrated, systems-comprehensive solutions that encompass transducer design, signal processing, power amplification and even electroacoustic measurement systems. As a result, Meyer Sound's engineering teams have earned an enviable reputation for developing unique, innovative solutions to some of the most difficult problems confronting audio professionals.
In fact, it is fundamental to John Meyer's philosophy that no component of a system should be compromised in order to compensate for variables "upstream" or "downstream." Instead, the entire system should be conceived, designed, tested, confirmed and manufactured as a whole to provide the optimum blend of audio fidelity, utility and long-term reliability.
Used Speaker Accessories
Speakers are generally output devices used by computer systems, and these usually have speaker accessories such as speaker hardware, cables, mounts, stands, etc. All speakersâ?? function amplify sound or audio output so it can be heard by other listeners easier. There are speakers that are built to work particularly with computers while there are those that can be linked to any kind of sound system device. The speakers function as transducers that transform electromagnetic waves into sound waves that can be heard by listeners. They receive audio input from source devices like the computer and with the use of speaker accessories the sound is amplified. Analog sound waves are converted into digital sound waves and are produced from digital speakers.
The speaker cables serve as connectors between the input devices and the speaker. Computers and other audio devices will need compatible cables to be able to connect with the speakers and produce amplified sound. The speaker mount are speaker accessories that act as support. They are needed to properly place and hold speakers so they can function properly. There are wall mounts and brackets for the ceiling. Different mounts are needed for different sizes and location for placement. The speaker stand is commonly used in surround systems and these are speaker accessories that help position the speaker devices efficiently. These are usually adjustable. The speaker rigging comprises the support system of speakers. Normally, if there is not rigging provided, the speakers are simply stacked on top of the other on stage.
