| Analogue VU Meters (Enclosed). Condition is Brand New. Dispatched with Royal Mail Signed For® 1st Class or Royal Mail International Tracked Europe. Enclosed Stereo VU meters with automatic audio input detection back light control. Our VU meters are unique on Ebay! The only units that you do not need to switch on and off every time you play your music. With a low power standby mode, industrial grade electronics, high contrast meters and a pair of connectors for easy connection to your system the 994VU-VT is a high quality easy to use product that looks good and designed to provide years of service with no user interaction required. Wide input scaling -20dB to +5dB (most competing models only scale to +3dB peak) The unit is presented in a compact, black textured ABS enclosure with dimensions of 16cmW x 16cmD (14cmD excluding connectors and controls) x 6.cmH. Rubber feet are fitted on the bottom of the enclosure. An IEC connector on the back panel accepts a mains input voltage of 85-240VAC. Two pairs of gold-plated RCA connectors are included for stereo audio input and output so that the unit can be easily connected between a playing device such as a DVD player, media streamer, set top box etc and amplifier. A front panel mounted premium quality combined rotary switch/potentiometer, fitted with an attractive black aluminium fluted knob, switches the unit on and off. Front panel control allows you to place the unit on any suitable shelf and still get to the main control even with restricted space above the enclosure. The potentiometer controls the VU meter back-light brightness and the lighting switches on automatically when a stereo (or mono on right Channel) input is detected. The lighting switches off in the absence of an audio input after approximately 15 minutes, this is low power standby mode. The meters are round dial and include back-lit internal near white LEDs giving the instruments a very modern appearance when lit. High contrast makings and black needles allows the movements to be seen working from across the average sized room without being large and obtrusive. The 994VU-VT includes high quality component parts meeting applicable safety standards. The PSU powering the VU meter movements and circuits processing the incoming audio signals meets the Audio/Video information and communication technology equipment - Safety requirements (CB) standards IEC62368-1 2014, 2nd edition and EN623689-1 2014 +A11:2017. Please see the photos. We pre-set the unit to 0.7745V RMS at 0dB but could set it to consumer line level input (300mV RMS at 0dB), professional line level (1.228V RMS @ 0dB) or set for your speakers, whichever suits you. The 994VU-VT is very accurate and will display 0dB across the whole audio range of 15Hz to 22kHz at the pre-set set input voltage. The meter has a gradual roll off (see graph) at higher frequencies. An additional exclusive feature is the ability to connect the 994VU-VT directly to amplifier speaker output terminals after suitable calibration. This is done using two speaker attenuation potentiometers fitted to the 994 pcb housed inside the enclosure. Email your speaker RMS wattage rating and the nominal impedance and we will set the unit for you. The internal power supplies have an EMC Class B rating and are EN62233 certified. The 994VU-VT is supplied with an IEC mains lead and socket with a standard UK 3 pin mains plug for UK customers and a CEE7/7 Euro plug for customers in Europe.

Weight: 515 grams excluding mains lead. Textured top, base, sides and front panel. Our own in-house FR4 industrial quality 994 pcb. FR4 is used in high end audio and industrial equipment. Industrial Quality Parts: The parts used in our VU are high quality and cost more than cheap overseas VU meters for increased reliability. On-board protective fuses for power stages. Electronic regulation of lighting brightness via front panel mounted rotary control. Separate on-board power supplies for lighting and VU audio circuits. Our connectors sample the signal only, no pass-through occurs that could degrade the audio signal. Pre-set to 0.7745mV RMS at 0dB Scaled from -20dB to +5dB. On-board speaker input attenuation via potentiometers for direct connection to speaker outputs from amplifiers/receivers where low level signalling is not available. Can be pre-set if you provide the wattage and nominal impedance of your speakers) Properly scaled to display correct percentage levels according to input signal strength. See Graph. Always on design with automatic switching to low power standby (meter back lights turn off) after approx. 15 mins if no audio input is detected. All metal film resistors on audio inputs for low noise operation. Works with any amplifier/receiver or audio device with a common negative output configuration. Many amplifiers and receivers and many audio devices are configured this way, some amplifiers including Class D may not be suitable. Front Panel features: Combined Off-On premium quality switch with back light brightness control & a pair of elegant round dial back-lit VU Meters with zero scale adjustments. Rear of pcb connections for:- Mains Input and left (black) and right (red) gold plated RCA audio input, left(black) and right (red) gold plated RCA audio output to amplifier. We are proud of our 994VU meters, they work well, look great and our customers agree. Here are two comments we have received from clients who have purchased units via Ebay:- Customer in Italy: "I wanted to tell you that the vu-meter arrived and works perfectly. All perfect" Customer in UK: "I just had to buy another one, brilliant" |
