Welcome to PHONOPREAMPS.COM on TCC TC-740A Mic/Instrument/Line/Phono Preamp with Input Attenuator New! Now includes improved regulated power supply usable worldwide! If connecting to a computer, simply substitute it in the diagram for the receiver shown below. Use the sound card's LINE INPUT jack, NOT the MIC IN. Any of the following labelled amplifier/receiver/minisystem input jacks can be used; AUX, TAPE IN/PLAY, LINE IN, CD, TUNER, MD (MiniDisc), VIDEO or DVD (use the L&R AUDIO jacks so labelled; ignore the actual yellow VIDEO jack if present). A variable level output control and the ability to handle line, musical instrument pickup, dynamic mic AND phono input signals makes this little item very handy indeed. This is an excellent front end for sound reinforcement applications that don't require the complexity of a mixer but may have to handle various source and output level requirements from job to job. DJs and roadies will benefit from having one of these in their tool box to take the place of larger, more expensive equipment in a pinch. PLUS the TC-740A adds a rear-panel attenuator switch to allow use with higher level line sources which exceed the TC-740's input capabilities, such as CD players, tape decks and MP3 players. $57.50 plus shipping 12 volt DC operation; will work anywhere in the world RIAA freq response 20hz-20,000hz +/- 0.5dB, S/N ratio 85dB Gold plated jacks and black anodized metal casingLED power indicator; output gain control Switchable RCA or 1/4" inputs with line attenuator selector Switchable for line, dynamic mics, instrument pickup or phono Ground wire terminal; click HERE to see why you need this feature Dimensions 142mm x 80mm x 46mm One year defective exchange warranty We include free of charge a stereo patch cord (for connection to a stereo) and a mini-plug adaptor (to use with computers).
