pT2-500 Microphone Preamplifier OPERATION MANUAL INSTALLATION Unpacking Please read and follow instructions on the Caution sticker on the anti-static bag enclosing the pT2-500: Please ground yourself to dissipate static electricity before opening anti-static bag and handling the pT2-500. Save the anti-static bag, carton, and foam supports for future storage or shipment. Card Rack Installation 1. Turn off card rack AC power and remove AC power cord. 2.
pT2-500 Microphone Preamplifier OPERATION MANUAL OPERATION Connections Read “Safety and Operating Precautions” on page 3, and “Installation” on page 6 of this manual before making any connections to the pT2-500. 1. Connect output signal cables from the XLR OUTPUT connectors on your 500-series compatible card rack to the analog line-level inputs of your DAW, recorder, mixer, A/D converter, signal processor, etc. XLR outputs used with unbalanced cable configuration must be wired correctly.
pT2-500 Microphone Preamplifier OPERATION MANUAL CAUTION: We recommend that you avoid “hot-patching” microphone inputs when using a patch bay at the microphone inputs of the pT2-500. Please TURN OFF phantom power and turn down the gain prior to connecting or re-patching microphone inputs routed through a patch bay. Failure to do so may result in transients that can damage the pT2-500 or equipment that is connected to its outputs-not to mention your ears! Instrument Input and Thru (DI) 1.
pT2-500 Microphone Preamplifier OPERATION MANUAL A Word About Cables… Most users of the pT2-500 have invested much time and money in their selection of microphones and preamplifiers. We recommend that you give some consideration to the microphone, instrument and output cables you select, as well. Use high-quality, low capacitance cable. Braided shielding and “star quad” type mic cables will perform better in electrically noisy environments.
pT2-500 Microphone Preamplifier OPERATION MANUAL Front Panel Layout CONTROLS Gain The detented rotary gain control along with the HI GAIN button setting determines the overall gain through the preamp. When HI GAIN is off, the rotary gain control range is from 6dB to 58dB and maximum input level is approximately +22dBu. When HI GAIN is on, the rotary gain control range is from 18dB to 70dB with maximum input of +10dBu. Polarity Output signal polarity is reversed when the POL button is depressed.
