8051 采用人手制造的模拟压?器，它提供6路变压器的平衡通道，同时含2路 side chains及一个 key 输入. 电路设计基于 2254 型号压?器 ? 反馈电路采用我们出色的33609 立体声压限器，? 8051 提供有名的 Neve 音色. 灵活的 side chain 路由, 微调 和 滤波强大功能令环绕声混音和母带制作有更好的效果。

Side Chain A 或 Side Chain B 可以控制任何一个通道, 同时6路音频通道可以任何格式分开联系到2个 side chains. 例如： 在 5.1 混音时由Side Chain A 压?中置通道（Centre），但同时输入 Side Chain B 控制环绕信号通道的压?。
8051’s 能调出平滑流顺，极其通透的模拟声音， 使用简单, 灵活而个性化的音色设置, 让 8051 成为世界其中之一最理想的环绕声混音与母带制作的压限器。 它可以单独一台使用或安装于Neve 88RS 系列调音台之中，成为调音台的6路压限器
