1.3.1 Unpacking
Carefully open the shipping carton and check for any noticeable damage. Every
Brüel& Kjær amplifier is tested and inspected before leaving the factory and should arrive
in perfect condition. If found to be damaged, notify the shipping company immediately.
Only the consignee may institute a claim with the carrier for damage incurred during shipping.
Be sure to save the carton and packing materials for the carrier’s inspection.
It is also advisable to save the carton and packing material, even if the amplifier is undamaged.
Should you ever need to ship the amplifier, always use the original packing.

1) Carry/protection handle: both handles can be used to carry the amplifier; they also act
as protection for the front panel. In fixed installations, or where rack front covers are
too shallow, they may be removed by unscrewing the retaining bolts behind the front
panel (see Step 17) on page 2).
2) Input level attenuators: these controls influence the input signal level. They are calibrated
in dB to assist the setup of active loudspeaker systems or cut down unwanted noise
from the input signal (see “Input Attenuators” on page 17).
3) Clip/limit indicator: this indicator signals when the amplifier output is clipping or limiting.
It has two different indication states:
• if the clip limiter is engaged, it has a short time constant and illuminates briefly (see
“Indicators” on page 18)
• if the clip limiter is not engaged, it has an increased time constant and illuminates for a
longer period
4) Protect indicator: this indicator illuminates if the amplifier tries to operate above its
maximum operating temperature (90°C). The indicator first comes on as a warning to
