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 Effects and Multi FX
Effects and Multi FX devices are devices that used in audio recording to alter the sound of audio sources like musical instruments by employing a range of digital sound effects. Also called a DSP Processor, Effects and Multi FX devices can alter audio sounds in a variety of different ways, and these changes can be either extremely subtle or hugely dramatic, depending on the type of digital effects unit which is used.
A Multi Effects processor can be used in both sound recordings or live during a performance. Effects and Multi FX can be employed to great effect with a wide variety of musical instruments, although they are most often paired with electronic instruments such as keyboards, bass and electric guitars.
Musicians and sound engineers use Multi FX devices such as fuzzboxes and wah-wah pedals to create a class of seven different sound effects, including Distortion, which clips the audio signal of an instrument, distorting the form of its sound waves and also adding overtones.
Other sound effects which can be achieved by an effects processor include Dynamics, which simply boost the volume level, Filter, which is applied to alter an audio signalâ??s frequency, and Audio Feedback, which was pioneered by the legendary Jimi Hendrix. Effects and Multi FX processors are also used to create sounds that have irregular tonal properties, an effect known as modulation, and can also modify the Pitch of an audio signal.
Lastly, an FX processor can also add time-based effects, such as delays or echoes.
