Product Description

The Symetrix 303 Interface Amplifier creates a proper interface between consumer and professional audio gear. This tool provides bi-directional level-matching and balanced/unbalanced conversion between professional (+4 dBu nominal level, balanced) audio equipment and consumer (-10 dBV nominal level, unbalanced) audio components. The 303 has two completely separate channels of conversion and level matching in each direction (from -10dBV to +4dBu, and from +4dBu to -10dBV). This means that, in each direction, the 303 may be used as a stereo interface amplifier, or as two mono interface amplifiers. All inputs and outputs may be used at the same time, allowing up to four channels of simultaneous levelmatching and conversion. Level-matching permits the connection of consumer and pro audio gear, while allowing both types of units to operate at optimal performance levels. A typical use of the 303 would be to connect a DAT, cassette deck or computer sound card (all of which generally run at -10dBV nominal level), to a professional audio mixer (+4dBu nominal level) or vice versa. The Symetrix 303 also provides conversion from unbalanced, -10dBV outputs to balanced, +4dBu inputs and conversion from balanced, +4dBu outputs to unbalanced, -10dBV inputs. This conversion can also be used to minimize noise and hum. 

     Low noise operation is also ensured by the Symetrix 303 s external power supply, which eliminates the possibility of power supply noise developing in the 303's circuitry.
