Page 7: Preamp Operation Instructions
Preamp Operating Instructions The 2-610 is a two-channel, vacuum-tube microphone/instrument/line preamplifier. Each channel has two gain stages that each utilizes a dual-triode tube operating in a class A single-ended configuration. Variable negative feedback is applied to both of these stages to control gain, distortion, and frequency response. -

Most modern condenser microphones often require +48 phantom voltage to operate. Each channel of the 2-610 has a toggle switch that applies 48 V to the MIC INPUT when the switch is up. It is good practice to keep phantom power off (switch down) when it is not required. To avoid loud transients, always keep phantom power off when connecting or disconnecting microphones. -
