This is a wonderful compressor/limiter/sustainer! Very clean and like new. The "magic eye" is a great way to get a quick and accurate visual on what is happening. This unit has been gently used in non smoking home studio. No issues whatsoever. Price includes CONUS shipping. US buyers only, no overseas sales.
From Cicognani:
FLORENCE 1176 is an optical compressor that is inspired and evolves the “signal way” of the historic compressor 1176. Unlike its predecessor, it uses a latest generation of optocoupler that allows us to offer three different modes of use: compressor, limiter, sustainer.
FLORENCE 1176 is a compressor that does its job without altering the tone of the sound. To do this we used the highest quality Jfet IC components combined with a sophisticated design. The new generations of opto couplers are more faster and for this reason the signal enjoys excellent benefits. This compressor can be used at the beginning or end of the effects chain with input signal levels up to a maximum of 1.5Vpp. Great together with tools (Guitar, Bass, Vocal, Drums) great with recording devices.
ATTENTION! The peak current of the tube in the preheating can exceed 1A (1000mA).
The HISTORY SERIES is equipped with an internal voltage doubler circuit. For this reason it’s necessary to use a stabilized power supply capable of guaranteeing a maximum working voltage of 12VDC with 500mA continuous.
Simple and intuitive to use FLORENCE 1176 offers great performance and three modality of use:
COMPRESSOR: The use of compressor is often necessary to guarantee a great sounds; a better length of the note played; to attenuate excess signal peaks thus ensuring a unique sound stroke.
LIMITER: The use of limiter it’s right when we want to get up to a certain output level threshold. In this mode the input level control will mark the exact point from where to start cutting.
SUSTAINER: the optical compressor sustainer is the mode of use with long release times combined with mid/hi ratio and hi sensivity input level.
COMPRESSOR/LIMITER/SUSTAINER
The function of compressor is to automatically reduce the level of peaks signal so that the overall dynamic range turn out better. Compression or limiting enables even the quietest sections to be made significantly louder while the overall peak level of the material is increases only minimally. In the digital age, the compressor offers great benefits and is especially important in recordings. It’s helps ensure that the signal is encoded at the highest possible level and offers a better signal definition. Other question, it helps to prevent a particularly harsh type of distortion known as “clipping”. This is one kind of limitations of digital technology.
RATIO selector allow four different modes:
4:1 (moderate compression)
8:1 (midd-hard compression)
12:1 ( best use to mild limiting)
20:1 ( best use to hard limiting)
It’s necessary to remember that a ratio of 4:1, however, means that any time there is an increase of 4 decibels in the loudness of the input signal, there will only be a 1db increase in output signal.
The decibel is a logarithmic form of measurement. Approximately 10db is normally required to increased the gain for a signal to sound twice as loud.
