1. Usually both authorized and pirate disks have 0.25-1.8Vrms volume while satellite TV stations output 0.08-2.12Vrms volume. The factors that affect the volume include: 1. Intact music pool, music list software setting; 2. Audio output settings of DVD, satellite, TV and karaoke player; 3. Volume setting of TV or amplifier, input and output volume adjustment of undertone player.
2. Volume regulator adjustment: maximize the volume of
VOD STB remote or computer terminals in VIP rooms (computer:“setting S”→
“control panel C” → “volume and audio equipment” , “sound card volume
adjustment”; VOD system’s music volume and remote volume, individual software
setting of songs in list) without any distortion
3. After the debugging mentioned above, if there are still some songs that have smaller volume than any others, enter the system’s song list setting to maximize their volumes; if still not loud enough, that means some songs are already beyond the capability of volume regulator. Please delete or replace these bad songs.
4. Users are only allowed to adjust amplifier’s volume not KOD player’s volume; it is not a good idea to control the volume via VOD player, because it may cause noises, distortion, impotent undertone or ineffective dynamics. KTV amplifier should have remotes, wire-driven jacks and touch screen to adjust its volume.
