The AH600-7 600W, 7-Band amplifier head is loaded with features like Pre Shape, which puts the signature Trace Elliot tone at your fingertips, and a specially designed Compressor that uses a studio-quality VCA with soft-knee threshold and adaptive attack and release times. Also included are a Mute function that will silence all outputs except for Tuner Out, plus a balanced low impedance DI output and an effects loop. With the 600W output stage, this unit can drive one of the large 4-ohm cabinets or a stack of any two of the 8-ohm cabinets.
