Vu meter mcintosh8/1/2023 ![]() Pre-amplifier and headphone amplifier with customisable crossfeed settings. What follows is a selection of ten amplifiers (eight loudspeaker, two headphone) that have come to market in the last three years and count VU meters among their feature sets:Ī4-size integrated amplifier, Class D (Hypex), 115wpc into ? Ohms. Some manufacturers – McIntosh, Luxman, Accuphase and Audio Research – never gave up on the bouncing needles. Technics and TEAC pulled the same trick a few years back. Yamaha has put VU meters on its latest batch of integrated amplifiers. However, as Technics and JBL have shown us in recent years with their respective turntables and loudspeakers – not to mention the vinyl revival – what’s old is new again. It also sidestepped the disparity between pro and consumer gear’s 0 VU point: +4dBu for studio heads, -10dBu for home listeners.īy the mid-90s, VU meters began to disappear from home audio gear, leaving a few niche hi-fi manufacturers and studio console makers to carry the torch for a once-ubiquitous feature. A dbFS meter could show transient spikes that a VU meter might miss. ![]() But just as the CD saw the digital domain encroach upon the hi-fi world, digital audio equipment’s db Full Scale (dbFS) metering began to invade the VU meter’s territory. No self-respecting audiophile would buy an amplifier without them. Corresponding VU meters would display the new ‘volume unit’ level but, because of the needle’s mass and non-zero rise time, the real-time measurement would be averaged over 300ms - this narrow time window would give listeners a more accurate display of perceived loudness.ĭuring the 1970s and 1980s, no self-respecting hi-fi manufacturer would omit VU meters from an amplifier or tape deck. Volume unit? Now we’re cookin’: a 1939 collaboration between Bell Labs, NBC and CBS that standardised loudness measurement. Movel it back and forth several times and this will hopefully fix the problem.VU. These switches have openings and in any of the openings, try to spray a considerable amount of contact cleaner. This is a switch that is commonly known as the record/play. In opening the deck, you will see a slide switch which is attached in the mechanism along with a linkage or rod. If there is a motion to the right upon turning it off, then there is something that drives the meter gauge to the left when the deck is turned on. Turn the power off to see if the needle in the meter gauge remains to the left. Power on the device and closely observe the meter gauge and the deck during stop mode. After this procedure, reassemble the box and try to observe if you will encounter the same problem. For plastic mechanical parts do not use lubricating fluid, instead use silicon oil. After all dust particles are cleared, try to drop some lubricating fluid on the mechanical parts. If it is filled with dust, you may use the blower or a small vacuum cleaner to eliminate possible causes of malfunction. Cautiously remove the covering of the assembly. Use your screw driver and remove the screws. These things may sometimes require cleaning, you may need to open the assembly and try to see if there are many dust particles in the system. If only one channel and one meter gauge is working, try to spray a little amount of DeoxIT at the back portion of your VU meter, particularly the IN/OUT. If either of the gauges work, then probably something is wrong. For VU meters with 2 gauges, it intends to measure sounds converted to voltage interpretation on the left and right speakers. There are different kinds of VU meter and it will depend on how the manufacturer designed the gauges, but they will usually function similarly. To know if your VU meter is malfunctioning, try to observe the gauges if they are working the way they should.
