Level 42 was also an early adopter of the brand. The company, now dedicated to manufacturing, moved to new premises in Witham, Essex, in 1985 to satisfy the growing demand. As PA systems improved, horn-loaded "bass bins" and subwoofers were added and were often well-equipped to amplify directly-fed bass guitar and keyboard frequencies. As well, in the 1980s and 1990s, monitor systems were substantially improved, which allowed sound engineers to provide on-stage musicians with a loud, clear, and full-range reproduction of their instruments' sound. As a result of the improvements to PA systems and monitor systems, bass players in the 2000s no longer need to have huge, powerful bass amplifier systems to play stadiums and arenas. Instead of playing with two 8x10" bass stacks and one or more huge, powerful bass heads, in the 2010s, many bass players perform at large live venues with relatively small and less powerful bass amplifiers. The reason they can do so is that most higher-priced 2010s-era bass amplifiers usually have DI output jacks that can be patched into the audio snake cable, and then plugged into the mainstage mixing board and amplified through the PA system or sound reinforcement system. In the 2010s, virtually all of the sound reaching the audience in large venues comes from the PA system or sound reinforcement system, the huge speaker systems pointed at the audience. As well, in the 2010s on-stage instrument amplifiers are more likely to be kept at a low volume, because when band members have their onstage amps "cranked" to high volume levels on stage, this makes it harder for the audio engineer to control the sound mix and blend. For example, if a heavy metal bassist had two 8x10" cabinets and several 1x18" subwoofer cabinets and several thousand watts of bass amplifier heads, and these amps are set to a very high volume level, this bass player will be creating very significant onstage bass volume. If the sound engineer wished to turn down the bass in the PA/sound reinforcement system, this bassist's loud onstage volume would make it hard for this engineer to control and/or reduce the volume of bass in the FOH (Front of House) sound mix. Another issue that can develop with bass players who have very high onstage volume is that it can be hard for the audio engineer to produce a clean sound through the PA/sound reinforcement system. For example,
