High Headroom High Impedance Preamp
Don't confuse preamplifier input impedance with rated microphone. The preamp should sound clean and unencumbered, regardless of the. A high impedance, high gain ribbon preamp solves that issue while unlocking. In significantly higher headroom and less noise when capturing quiet sources. Unsubscribe from AEA Ribbon Mics & Preamps? With 81dB of gain, JFET circuitry, and a super high input.
High Headroom High Impedance Preamp Schematic
The Khan audio VTMP is a full featured all tube microphone preamp and much more. Powered by 12AX7 and 12AU7 tubes, they are arranged in a classic feedback controlled gain block. Transformer coupled inputs and outputs are standard for full frequency response with minimal noise interference from the outside world. A rugged, high filtered power supply delivers the basis for the device.The VTMP has a microphone gain range of 35 to 57 dB. The 20dB pad allows use with hot microphones and signal sources without clipping.
It can also be used as a balanced line driver accepting nominal +4dB signals at the balanced line input jack. A high impedance instument input is also included with a thru jack for live/di use. A 6 position output pad allows the use of the overload character of the box. With a plethora of input and output configurations, the Khan VTMP can enhance your recording process. Specifications:. Instrument Input impedance 2.2M ohm. Max Signal Input: 3v RMS (+10dB).
