Product Description of Karaoke Auto Volume Regulator/Controller-KVC21A

KVC21A is auto volume regulator for professional and household computers.

Its advanced audio frequency signal processing technology adjusts volume automatically after one setting, so consistent volume will be gained no matter what its audio frequency source is.

It is to regulate the volume of KOD player, PA broadcasting system, computer, movie broadcast and broadcast station.

It can access one or two groups of sources with stereo RCA plugs, like satellite TV STB or cable digital TV STB, DVD player, KOD player (Karaoke player, Karaoke machine, Jukebox) and computer. Any two of those audio outputs are sent to two input interfaces on KVC21A.

It also has one RCA output interface and one 3.5mm stereo output interface, which are selected by the switch on top and then sent to TV or power amplifier, multimedia loudspeaker and earphone.

KVC21A takes sampling and controls the outputs for both left and right tracks; it will amplify 20dB automatically if the sound signal is too small, and attenuate at least 16dB if the sound signal is too big.

It has power switch, BYPASS switch, input one-out-of-two switch, output one-out-of-two switch, power indicator, round volume knob on the top of VR-5. This machine is serially connected between the player and TV (or professional power amplifier), so the volume can be regulated automatically during switching stations, videos, songs or ads.

It has auto balance function for left and right track and input buffering function. Audio output is adjustable among 0-0.7V and its auto balance range is 0.03V-7V while keeping music dynamic.

This machine can be placed on the top of other chassis and get electricity from power adaptor. If it works together with computer, its round output volume knob on its top is used to adjust the output volume without changing any computer setting.

Setting: When installation, keep maximizing the output volume of satellite or digital TV STB, hard disk player, DVD player, KOD player, computer, MP3 player, video game console and ad player without any distortion to get best dynamic music and stable and balanced volume
