The main features of the Proton 740 are: 2 heads, electronic linear tape counter with 4 digits and memory stop, automatic tape type selection with support for normal, chrome and metal tapes.
Typical front loading cassette deck with the cassette compartiment located on the left side of the deck. Tape eject is operated mechanically and the cassette needs to be placed with the side to be played facing forward in the cassette well.
Level meters used on the 740 are generic digital peak reading meters with peak hold for easy adjustment of optimum recording level. Full-logic transport controls used on the 740 let it respond to the slightest finger contact for fast and effortless transport function selection.
Dolby C-type used in the 740 provides 20 dB of noise reduction above about 1,000 Hz, fully doubling the amount given by B-type. Dbx Type II found in the 740 is a simplified version of the Type I noise reduction system. The dbx Type II system was designed to be used with systems with limited bandwidth such as cassette based recorders and also uses a simple 2:1:2 compander to reduce noise. To further maintain recording accuracy, the 740 incorporates a switchable multiplex filter. When you record FM stereo broadcasts, the MPX filter of the 740 can be swiched on to prevent the standard 19kHz FM pilot signal from interfering with the noise reduction system.
To make live recordings this deck has 2 microphone inputs to connect microphones with a jack connector. For undisturbed listening a jack connector for a pair of stereo headphones is supplied.
