How is the output balanced? Is it transformer balanced, op amp balanced, servo (cross coupled) balanced or balanced with resisters?
I need to decide whether or not to ground pin 3 when building a cable for direct connection to a guitar amp.
PLEASE REVIEW THE BELOW INFORMATION CAREFULLY:
The microphone in and of itself is not balanced; however, the permanently attached Power Module balances the output. The Power Module attached to some condenser microphones (including the PRO70) provides several important functions. First, it converts the 11 – 52 VDC phantom power (provided by a mixer or dedicated phantom power supply) into a smaller DC bias voltage which is used to power the FET impedance matching circuit inside the microphone. Also, it provides a low frequency roll off, some supply battery power if phantom power is not available, converts the signal to the proper impedance and balances the output. The power module is a necessary component.
IF YOUR GUITAR AMPLIFIER HAS A 1/4" TS UNBALANCED INSTRUMEN/LINE-LEVEL INPUT:
For connection to a guitar amplifier using a 1/4" TS unbalanced instrument/line-level input (typical), you will need an additional component; the Audio-Technica CP8201 Microphone Impedance Matching Transformer. The CP820 is designed to connect a low-impedance microphone (like the PRO 70) to a high-impedance electronic input (like your guitar amplifier). The high-quality transformer solves the problem of excessive high-frequency loss and hum pickup. You would essentially connect the permanently attached Power Module of your PRO70 to a standard XLR cable, then connect the opposite end of the cable to the CP8201, then connect the CP8201 to the 1/4" input of your guitar amp.
IF YOUR GUITAR AMPLIFIER HAS A 1/4" TRS BALANCED MICROPHONE-LEVEL INPUT:
For connection to a 1/4" TRS balanced microphone input, then you will need a balanced cable XLR - 1/4" TRS cable, such as the Pro Co BPBQXF10. In this case, you would essentially connect the permanently attached Power Module of your PRO70 to the Pro Co BPBQXF10, then connect the 1/4" connector of your Pro Co BPBQXF10 to the 1/4" input of your guitar amp.
However, to answer your question more directly, it is transformer balanced via the power module.
