1.9.1 Intake/Exhaust Air Ducts
Fig. 31 Intake air duct (1) and exhaust air duct (2); here R&S NV8304 with option intake air from below
The air from the intake duct is drawn in by the fans and forwarded to the distribution shaft.
The distribution shaft provides enough air to each amplifier to cool it. The heated air is rout-
ed to an air collecting shaft on the opposite side of the amplifier and expelled via the ex-
haust duct.
Note The intake/exhaust outputs are located either on the top or bottom of the rack, depending
on your order specifications.
