Preamplificatore microfonico Mono a rack - PSU Incluso
The 312A is available as a 500 series module or a single or dual channel 19" rackmount.
Because there are no capacitors in the audio path, the 312A is super fast and punchy, allowing transients to pass easily, making them a favourite for drummers.
Made with the highest quality parts including Jensen input and output transformers and the BAE 2015 opamp. The 312A also includes a high impedance DI for instruments.
Made using BAE 2015 opamps
Supplied with Jensen input and output transformers.
Remote power supply with four-foot cable capable of four times the current needed by the preamps for optimum sound quality.
Switches have gold contacts for long life.
XLR connectors on the back for mic input and output and phone jack in front for direct input.
High impedance direct input for guitar and synthesizer.
Separate front panel switches for phantom power.
