Samson C Valve Tube Microphone Preamp    Item #: SAM CVALVE 

The Samson C Valve adds the warmth of analog tubes to digital recordings.
The Samson C Valve is a true tube preamp that provides pure signal and silky sound. The C Valve features variable gain and variable tube process saturation for adding harmonics. Regardless of which mic you use, it will maintain detail and transparency. 48-Volt phantom power, phase and peak limiter round out the control set. A large analog VU output meter and a 6-segment LED input meter make it easy to adjust the gain. Use its insert points along with a C Class Compressor for a direct path to a gorgeous front end sound. The C-valve provides a digital output as well.

Samson C Valve Features

• A high quality microphone or instrument pre-amplifier using discrete transistor and tube gain cells.
• On board Limiter for leveling the output is useful in recording and live sound applications.
• The total amount of harmonic overtones or “warmth” can be controlled using the Saturation control.
• An Input Gain control is included to maximize the overall input gain stage, handling levels from microphones or instruments.
• A pre-set “sweetening” equalization curve can be added using the Enhance switch.
• Positive or negative phase can be selected using the Phase switch.
• The addition of an Analog VU meter makes it easy to read the Output Level.
• 48-volt phantom power for powering condenser microphones is available by pressing the LED, backlit, 48-Volt push switch located on the front panel.
• S/PDIF output via an internal, high quality A-to-D (analog-to-digital) converter sends 24-bit digital audio to hard disk recorders via the rear panel RCA connector.
• Sample rate selection via the front panel, backlit switch allows 48 or 96K sample rates.
• Six segment LED Input VU meter displays the level after the Gain control.
• Convenient 1/4-inch insert points are included for external signal processing.
• Balanced XLR microphone input and 1/4-inch balanced line input connectors allow easy hook up of mics or instruments.
• Oversized, rubber bumpers with tilting feet allow several Samson C class units to be stacked and tilted in an ergonomically correct operating position.
