INSTALLATION AND OPERATION 12
musikelectronic geithain GmbH RL-Amplifier 2
7 Installation and operation
Every amplifier output is paired to exactly one speaker by the same serial number. The according
serial number is located next to the output. Ensure installation in pairs.
During installation ensure sufficient convection at the heat sink. The amplifier should not be installed
below devices that tower above it.
In case of rack installation the amplifier is only screwed to the rack through the face plate. Therefore
ensure secure mounting.
Before start-up check the mains voltage stated on the backside of the device. If your local mains
voltage does not match the specification of the speaker, please refer to your retailer or direct
distribution. When the stated and your local mains voltage comply connect the mains connector
(11)
to the socket with the included mains cable.
For further connections, ensure the amplifier is turned off (display unlit). In case the display is
blue, turn of the device by pressing the power button at the front of the device (1) . Now connect
the speakers with Speakon cables to the amplifier (10) . To minimise EMI distortion that could be
produced by the device we advise the usage of the Speakon cables sold separately by Musikelectronic
Geithain GmbH. Connect the signal source to the amplifier through the analogue XLR connectors
(8) . For digital signal sources use the digital AES/EBU input (9) .
7.1 Cable connections
The input of the integrated amplifier is electrically balanced. When your signal source also utilizes
balanced connectors, please use a cable wired as stated in the table:
Balanced
connector (Amplifier)
Balanced
connector (Signal source)
Unbalanced
connector (Signal source)
XLR XLR RCA
Earth Pin 1 Pin 1 Ring
Pin 2 Pin 2 Tip
Signal - Pin 3 Pin 3 Ring
When using a signal source with unbalanced outputs (RCA) you need to balance the connecting
cables. This avoids hum and other noise interferences. The table and the following figure show the
wiring.
