Swiss pumpkin nagra jazz tube pre-amplifier brand new genuine warranty
JAZZ is the latest pure Class A tube front stage launched by NAGRA in 2012. It inherits NAGRA''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s consistent elegant shape and adopts the newly developed shortest signal path design circuit, so that the sound of the vacuum tube machine can reach high density and high on a natural and balanced basis. The level of analytical power meets the requirements of today''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s most discerning music enthusiasts. JAZZ follows its usual military-grade production requirements, using three strictly selected vacuum tubes and NAGRA special transformers to provide an unparalleled sound clarity (each vacuum tube is fully warmed up and fully tested for 48 hours to ensure the highest Performance level). The latest split power supply ACPS II can completely isolate AC line noise and provide the highest quality quietness and stability necessary for audio systems. The output of JAZZ is directly coupled to the output vacuum tube, ensuring the highest audio performance. And you can use the dial button on the front panel to set the output level at 0 or +12 dB, so that it can be more perfectly matched with the post-amplifier. Equipped with NAGRA''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s traditional highly accurate modulometer meter, which can be used to adjust the volume and fine-tune the balance between the left and right channels to compensate for the differences between recordings of different levels.
The aluminum alloy case is the same as the PL-P front stage, adopts the same panel, provides input selection, balance, volume control, and is equipped with a typical Nagra indicator. The Jazz front stage is a new design, no need to use battery power, can keep the background quiet; bandwidth 10Hz-50KHz, loss of 0.01%, very professional performance, with remote control. The Jazz front stage is powered by an external power supply. Nagra designed an ACPSII power supply device that can maintain extremely low noise and maintain a channel separation greater than 75db. All signal sources have been turned from the side to the back. There are 5 sets of RCA and a set of unbalanced XLR input terminals. The power input uses LEMO headers, which are extremely advanced. Jazz uses three empty tubes for amplification, and each tube has undergone 48 hours of burn-in testing to ensure the highest performance; the signal source is directly connected to the output tube, making no compromise.
