Avalon microphone preamplifiers have been in use around the world since 1986. All preamplifiers share the combined technologies of low ratio transformer balanced inputs coupled with high-voltage cascade FET twin bipolar discrete class A amplifiers.

• 100% discrete, pure class A mode
• Transformer coupled inputs
• Musically balanced harmonic detail
• Low noise, high headroom +30dB
• Variable highpass filter on M5
• B&K 130v optional card on M5
• Accurate 2dB stepped gain control
• High impedance DI instrument input
