The booster amplifier is delivered for tabletop use, but you can mount it in a 19" rack using the brackets supplied
with the unit. In case of rack mounting, you must:
remove the 4 feet from the bottom of the unit. Without the feet, the LBB1930 and LBB1935 are 2U high and the
LBB1938 is 3U high.
leave 1U empty rack space above the LBB1930 or LBB1935 to ensure sufficient air flow.
ensure that the ambient temperature of the unit in the rack does not exceed 55 °C.
In case of rack mounting, removal of the top cover of a booster amplifier is allowed to improve the ventilation. In
such a case, always use the shimming washers that come with the brackets and make sure to comply with the safety
instructions. The amplifier has a built-in temperature controlled fan for reliable operation at high output power for a
prolonged time. If the internal temperature reaches a critical limit due to insufficient air flow, overload or an
excessive ambient temperature, the overheat protection will be activated, causing the amplifier to switch to standby
mode.
