® IT’S TIME TO CHANGE THE CHANNEL! The standard of excellence for channel strip processors has just been raised. From the world leader in signal processing comes the new 376 Tube Channel Processor with Digital Output. ® dbx Professional Products has been paving the way for audio excellence for more than 25 years, and with the introduction of the 376, the drive continues. The 376 has taken the standard features ® of a channel strip processor, added the classic dbx 902 De-Esser and turned the channel strip market on it’s end by combining digital outputs and a tube as standard features. It’s no longer necessary to have a separate tube preamp for classic analog warmth and external analog-to-digital converters for digital recording. The 376 brings them both together with world-class analog signal processing, making it the perfect companion piece for tracking vocals and other mic’d applications in the analog or digital domain. The 376 Tube Channel Strip w/Digital Output is the latest addition to the Silver Series family. The 376 puts the best of both worlds into one affordable package by combining the warmth of the vacuum tube with the pro- ® prietary dbx Type IV™ conversion system. The 376 boasts many of the same features as other products in the Silver Series such as +48V phantom power, a phase invert switch, and low cut filtering. The 376 also offers digital output in both AES/EBU and S/PDIF formats. The high impedance, 1/4" instrument input located on the front panel as well as the mic/line switch and 20 dB pad show our dedication to providing convenience in the studio. The LED meters provide a clear and concise visual of the signal at a glance. The rear panel includes both mic and line inputs and outputs, word clock sync input and output, insertion jack and digital outputs. Add selectable sampling rates of 44.1 kHz, 48 kHz, 88.2 kHz, or 96 kHz; selectable dithering and noise shaping; and selectable analog and digital output metering to this already impressive list of features and we think you’ll agree ® that the 376 lives up to the uncompromising standards of dbx Professional Products. • Tube microphone pre-amp • Type IV™ conversion system • 200V tube plate voltage • Selectable sampling rates (96, 88.2, 48, 44.1kHz) • Selectable mic/line switch • 24, 20 and 16 bit wordlengths • +48 Volt phantom power • AES/EBU and S/PDIF digital outputs • 3-Band Parametric EQ • Selectable dither and noise-shaping algorithms • Compressor • Word clock sync input and output • De-Esser 8760 S.
