SYSTEM DESCRIPTION 5
musikelectronic geithain GmbH RL-Amplier 2
3 System description
The RL-Amplier2 is a device especially designed as a separate 19inch rack amplier for 3
channel studio monitors from Musikelectronic Geithain GmbH. The device has PWM power
ampliers to allow operation with convection cooling in a compact 19-inch housing. It
offers technical protective measures to ensure safe operation of the attached loudspeaker.
It is designed for users searching for a device with minimum space requirements. The use of a
digitalsignalprocessorallowsforexibleadjustmentofthefrequencyresponsetotheacoustical
environment. Integration into digital production work chains is easily possible due to the AES/EBU
input.
