    High Gain Audio Phono/Mic/Aux Preamp


The TC-770LC is a device that permits the interconnection of a number of audio sources. It incorporates
a high gain, accurate phonograph stage, a microphone stage, and an auxiliary input stage. Gain or volume
is front panel adjustable.

It incorporates the same 40dB phono stage found in our other MM preamps, then adds an additional gain
stage providing up to 20dB of adjustable gain. his is the perfect solution for those low output moving magnet
cartridges like Bang & Olufsen that provide too little signal to drive other phono preamps adequately.

The TC-770LC is perfect for connecting a turntable to a Hi-Fi system that has no phono input , or for adding
a second turntable to a system that has only one phono input It can also be used with the line input on any
computer sound card to permit phono playback thru PC multimedia systems for recording onto hard disc
and editing, as well as producing CD copies and MP3 recordings for your mobile portable music collection.

The additional gain stage is available should it be needed to drive insensitive inputs or overcome losses
caused by a long cable run to the amplifier or receiver.MP3 players and iPods which are annoyingly weak
when connected directly to your home stereo will become much louder and properly match other sources
when connected thru the TC-770LC's front panel jack..
