Gemini PA-7000 Professional Preamplifier Review

Average Reviews:

(More customer reviews)I purchased the PA-7000 preamp to expand the number of inputs and outputs on my component HiFi system. I am using the tuner input with a Denon TU1500RD Tuner, the phono input with a circa 1980 Denon Turntable, the tape input with a circa 1970 JVC Cassette Player/Recorder and the AUX input with a Direct-TV DVR. The PA-7000's unbalanced output (ordered balanced cables for future upgrade) drives a PreSonus Central Station Controller which then drives a Furman SP20AB Amp and a set of custom-upgraded, Infinity Speakers. I listened to the PA-7000 with Beyerdynamic DT770 headphones as well as speakers, at maximum volume, and the noise and hum levels are barely audible. The phono preamp sound quality is excellent and my wife could hardly believe it when I played some records, how clean and natural they sounded. The only minor audio performance flaw I noticed is some crosstalk between the adjacent inputs with the volume set to maximum. This is not a major issue for me, as only one of the input devices would typically be turned on at a time. The tone, balance, volume controls and other front panel buttons work as advertised and all the controls are smooth and crackle free. The chassis finish is nicely done but the mid-point detents on the control knobs do not line up with the markings on the chassis. I did not test the microphone input but overall, for the price, the performance of the PA-7000 exceeded my expectations.

This preamp can help you get your sound that little extra boost it needs before going into your rack! It also acts as a source switcher, letting you choose between a total of four inputs and three outputs. The primary outputs are also XLR line-level for direct connection to most power amps an/or professional signal processors. This is an ideal choice for DJ's, permanent PA installations, or home theater enthusiasts.
