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.
