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.
