RAXX Inline Stereo Phono Preamp 9V Battery Operated for Turntable Record Player

RAXX Stereo Phono Preamp This is a dedicated stereo pre-amplifier box that boosts the signal level from your turntable/record player to a signal level required for a standard Hi-Fi system or receiver unit. This inline phono pre-amp is necessary if your main amplifier does not have a dedicated phono input. This unit is powered by a standard 9V battery (not included). On the chassis, you'll find two screws that keep the lid on tight. These screws also allow you to mount your turntable's ground wire to the chassis and remove any unwanted hum in your record playback. Features: - Low noise circuitry- RIAA EQ compensation- On/Off power switch- Earth/ground screws on chassis for removing hum- Powered by a 9V battery (not included)- Suitable for "moving magnet" pickups- Compact metal chassis Why do I need a preamp? A phono pre-amplifier is designed to boost the signal from a turntable or record player before the signal is passed to your Hi-Fi amplifier or receiver. Typically the signal output from a turntable or record player is quite weak, and it's required to be boosted before it hits the main amplifier of your stereo or hi-fi unit. On the Flip-Side... Some hi-fi amplifiers or receivers have a dedicated "phono" input and some modern turntables have a "line" level output - this simply means they have a phono preamp built-in and an external one is not necessary. But if your system or player doesn't have this feature built-in, you'll need a separate preamp (like this one). Instructions: Open the chassis of the RAXX phono pre-amp and connect a 9V battery (sold separately) Connect the left and right channel outputs of your record player to the L and R input jacks of the RAXX phono pre-amp. If your turntable has a ground wire, connect it to one of the screws on the chassis of the RAXX phono pre-amp. Connect the L and R outputs of the RAXX phono pre-amp to the left and right line input jacks (CD/AUX/TUNER, etc.) of your stereo amplifier. Switch the unit on and enjoy your favourite records! Note: When the sound quality deteriorates, it is time to replace the battery.Input Impedance: 50k ohms at 1kHzOutput Impedance: 50k ohmsAmplitude Gain: 34dBRated Input Level: 3mVMaximum Permissible Input: 38mVOutput Level: 1.8V RMSFrequency Response: 30Hz to 20kHz +/-1 dBCompensation: RIAA with deviation less than+/-1 dBSignal to Noise Ratio: 50dB with normal inputCrosstalk: Better than 50dBPower source: 9VDC Battery (sold separately)Current Drain: 1mA averageDimensions: 85 x 27 x 58 mmWeight: 5.5g
