312A Features

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.
