The SIM Series featuring SIM910 amp; SIM911 mdash; JFET amp; BJT pre amplifiers designed primarily for small signal applications. SIM911 is built to have low input noise and 100 kOmega; front – end impedance. SIM910 is ideally use in high impedance sources with low bias current and 100 MOmega; input impedance. Easy to install with its dual parallel outputs (one front and one rear) provide flexibility in cabling. It can be powered by both AC or DC, with a built-in indicator in case of overload condition. Its compact design allows portability and can withstand even the most demanding of application.SIM系列具有sim910 sim911 &mdashJFET放大器BJT前置放大器的主是对小信号的应用。sim911建成具有低入噪声和100 kOmega前端抗。sim910是理想的使用在低偏置电流和100Ω的入抗抗源。易于安的双并出一前一后提供灵活的布线。它可以由交流或直流供电在情况下内置指示器。其紧凑的允的可移植性和可承受最刻的应用。
