The SPL Crescendo is a remarkable 8-channel microphone preamp that delivers unparalleled transparency, a vast dynamic range, and exceptionally low distortion. This compact unit occupies just 3U of 19" rack space while offering outstanding recording capabilities, capturing even the finest nuances with precision. SPL's commitment to technical innovation is evident in the Crescendo. The differential amplifiers employ carefully matched transistor pairs and are thermally coupled to achieve an impressively low level of thermal distortion. The discrete output stage op-amps operate with a 6mA dormant current, meeting the Class-A operation standard. A specially selected toroidal transformer power supply, shielded with custom-fabricated sheeting integrated into the Crescendo's housing, ensures minimal electrical interference and prevents power noise from affecting the preamps' performance. Each of the eight preamp channels on the Crescendo can be independently operated
