![]() ![]() VU meter where levels above 0 VU are shown as positive decibels (the range of potential distortion), and those below it as negative decibels. VU3 costs US 140 from Amazon including Prime shipping. It is kindly sent to me by testing by a special member. 0VU is the nominal operating level and, in the analogue world, that is usually (but not always) +4dBu. They indicate signal levels around the nominal operating level and they dont show the headroom margin at all. A meter which is linear in decibels (rather than percentage of modulation) is called a peak programme meter (PPM), and is commonly used in Britain.Ĭompare: GAIN, LEVEL RECORDER, OSCILLOSCOPE, SIGNAL-TO-NOISE RATIO, SOUND LEVEL METER, SOUND PRESSURE LEVEL. This is a review and detailed measurements of the Douk / Little Bear VU3 dual analog VU meter and 2-way amplifier/speaker switcher. SOS Technical Editor Hugh Robjohns replies: The VU meter (and the PPM) are analogue tools designed for the analogue world. The diagram below shows a VU meter with a decibel scale from -20 to +3 dB, and a linear percentage of MODULATION scale from 0 to 100% below it. Supplied with 1 front panel suitable for horizontal or vertical. ![]() LU Meter MK2 is based on the concept of Loudness Units, a way of measuring audio that takes into consideration the human perception of sound. In practice, analog devices have considerable headroom above 0 VU to allow for peak levels DIGITAL RECORDING systems, on the other hand, have little or no headroom because of their fixed DYNAMIC RANGE which is usually larger than with analog systems. VU meter with a scale consisting of 10 LEDs and an adjustable input. The HoRNet LU Meter MK2 is a digital loudness meter with auto gain staging and grouping functions, the redesigned and resizable GUI hides an intelligent tool that will improve your gain staging and mixing. On such meters, zero indicates the maximum DISTORTION -free level that can be handled by the device with other values greater or less than the zero level indicated as positive and negative decibels relative to it respectively. Thus, a VU meter is a device for measuring the level of SOUND INTENSITY with audio equipment, such as AMPLIFIER s and TAPE RECORDER s.Īlthough the measurements indicated on such a meter are in DECIBEL s, the zero level should not be confused with 0 dB, the THRESHOLD OF HEARING. ![]()
