Premium-Quality Preamp

With its range of high-quality components and rugged design, the Twin-Servo 500 Preamp is ideal for processing a range of equipment including condenser microphones for maximum audio fidelity. Radial have maximised the gain-margin within the preamplifer, resulting in minimal distortion for a range of different inputs. The sound is reproduce through the dual 990 op-amps with two servos and two Jensen transformers for maximum audio quality and minimal distortion. For monitoring, the preamp features a 10 segment LED meter so you can monitor your levels at a glance.

Exceptional Audio Quality

As well as the internal components and design, the Twin-Servo 500 also provides you with a varied amount of inputs to connect external devices such as microphones and guitars. The 500 series preamp produces up to 60dB of gain with a dual-gang potentiometer for level adjustment. The front-panel of the preamp also features a Neutrik Combo connector allowing you to connect either XLR or 1/4'' input. The pramp features 48V phantom power and an activation switch for use with phantom powered enable equipment such as condenser microphones. The preamp also incorporates a subtle high-pass filter that helps to eliminate excessive resonance along with a -10dB pad for added versatility.
