The UPM-2 operates as a system
with the P-2 Control Electronics Unit. Optimized for the UPM-2 and pre-aligned at the factory, the P-2 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-2 loudspeaker components from damage due
to overheating under high power conditions. This unique circuit continuously Monitors the power applied to the UPM-2 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-2
Control Electronics Unit give the UPM-2 flat frequency response with outstanding phase characteristics. A single-channel device operating at line level, the P-2 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 Processor Units
Processor units, often simply known as a DSP audio processor, are a sound-processing device that alters the sound of auditory signals. The processing of the audio signals may be either digital or analog. The analog processing involves the direct operation of the electrical signal while the digital processing involves the mathematical operation on the digital representation of the audio signal.
The audio signals are typically known as sound waves that are transmitted through the air. These sound waves are measured in decibels or bels. These audio signals need processor units especially in radio broadcasting because the processor units link the transmitter with the rest of the sound system devices. There are various methods involved in the processing of both analog and digital signals. These include the following: storage, compression, transmission, equalization, noise cancellation, enhancement, level compression, echo, filtering and many more.
Analog processing is the physical alteration of the uninterrupted signal by modifying the voltage, the current or the charge with the use of electrical means. In earlier times, analog processing was the only method being used to modify signals before digital technology came into existence. With the evolution of computers and software, digital sound processing became the alternative to analog processing. The digital processor units use digital circuits like the microprocessors and computers to process audio signals. Digital processing deals with sound waves represented by binary numbers and deals with the sequence of these numbers. Nowadays, audio systems typically use the digital processing method because it is more powerful and proficient compared to analog signal processing.
