Key Features
The 3500A includes selectable passive or active input, tube and solid-state preamps and variable compression. The 10-band graphic EQ allows you to create a broad range of tonal colours and a dedicated in/out button even lets you preset an equalization curve. Two fully adjustable contour knobs (high pass and low pass) also provide further control over shaping your bass sound.
An electronically balanced direct output provides a means of routing signal to professional mixing consoles in both live performance and recording environments. A ground lift switch also helps prevent hum or buzz from entering the signal and a pre/post switch allows the direct signal to be derived either before or after the amp EQ section.
For enhanced reliability, the 3500A features protection relay circuitry that protects connected speakers from dangerous overloading and even prevents "thumps" when powering on or off. Plus, rugged construction makes this amp totally roadworthy, so you can be sure you'll get dependable performance night after night.
