    • Circuitry for simulating and emulating the sounds of a loudspeaker driven by a classic rock and roll guitar amplifier in the form of an electrical signal which, when input to a recording console or used to drive high fidelity headphones or a high quality monitor amplifier and monitor loudspeaker, accurately reproduces such sounds. The circuitry is incorporated at the output of a classic tube-type rock and roll guitar amplifier, and consists of three basic modules: a load impedance module (Fig. 3) designed to offer to the tube amplifier output a load impedance as a function of frequency (Fig. 1) which is modeled after and nearly identical (in both real and imaginary components) to the impedance of a classic rock and roll guitar speaker; a highpass filter circuit (24) which emulates the low frequency resonance and rolloff characteristics (Fig. 7) of a classic rock and roll open-back guitar speaker cabinet; and further filtering circuits (26, 30, 32, 34, 36, 40) which emulate the mid and high frequency characteristics (Fig. 7) of a classic rock and roll guitar loudspeaker. Electrical outputs (50) are provided for driving a recording mixer, headphones, a speaker, and an external power amplifier.
    • 用于模拟和仿真由经典摇滚吉他放大器驱动的扬声器的声音的电路,其以电信号的形式输入到记录控制台或用于驱动高保真耳机或高质量监视器放大器和监视扬声器 ,准确地再现这样的声音。 电路结合在经典管式摇滚吉他放大器的输出端,由三个基本模块组成:负载阻抗模块(图3),设计用于向管放大器输出负载阻抗,作为 频率(图1),其被建模在经典摇滚吉他扬声器的阻抗之后并且几乎相同(在实部和虚部中) 一个仿真摇滚式回旋式吉他音箱的低频共振和滚降特性(图7)的高通滤波器电路(24); 以及模拟经典摇滚吉他扬声器的中频和高频特性(图7)的另外的滤波电路(26,30,32,34,36,40)。 提供电输出(50)用于驱动记录混合器,耳机,扬声器和外部功率放大器。
