An Introduction to the Ampeg SVTMP: The harmonically rich sound and legendary performance of AMPEG products are redefined in the SVTMP. This rock-solid chunk of equipment is worth its weight in gold on the stage, in the studio, or anywhere a quality microphone preamp is needed.
Features: • COMBINATION XLR/1/4” INPUT JACK: Transformer balanced microphone input on XLR connector, transformer balanced Line input on 1/4” T/R/S connector.
The Front Panel: 9 1 2 3 4 5 6 7 8 1. MIC/LINE: Connect a mic input signal to the balanced XLR jack by means of a high quality shielded cable. This input is designed for mic input sources only. Connect a balanced line signal to the inner 1/4” T/R/S jack. This jack is designed to accept balanced line level signals. 2. PAD: This switch, when depressed, attenuates the signals at the XLR mic input and the 1/4" T/R/S Line input by 20 dB and 10 dB respectively. 3.
8. BALANCED OUT: Use this jack to connect the transformer balanced output of the SVTMP to a mixer, recorder, DAW or computer soundcard. This balanced signal will drive long cable lines with very little loss or degradation of the output signal. (If the signal is too hot for the input device, engage the Output Pad (#7). 9. (GAIN): Use this control to increase the gain applied to the signals at the XLR mic input and the 1/4" T/R/S Line input by 35 dB to 55 dB and 25 dB to 40 dB respectively.
Important Information About Tubes And Tube Products: A Brief History Of The Tube: In 1883, Edison discovered that electrons would flow from a suspended filament when enclosed in an evacuated lamp. Years later, in 1905, Fleming expanded on Edison's discovery and created the "Fleming Valve". Then, in 1907, Dr. Lee de Forest added a third component – the grid – to the "Fleming's Valve" and the vacuum tube was a fact of life. The door to electronic amplification was now open.
Important Information About Tubes And Tube Products: Survival Tips For Tube Preamps: To prolong tube life, observe these tips and recommendations: • After using the preamplifier, allow sufficient time for it to properly cool down prior to moving it. A properly cooled preamplifier prolongs tube life due to the internal components being less susceptible to the damage caused by vibration. • Allow the preamplifier to warm up to room temperature before turning it on.
