Four high-quality stereo inputs receive the signals and with very loss of signal, pass them on through goldplated silver contact relays to the other modules. In order to meet high quality demands, the signal transfer and processing is done exclusively balanced, based on professional studio standards. Even vinyl fans will appreciate the I/O module as it offers an excellent phono input which can handle cartridge systems from both MC and MM devices. There is also an analogue Record output for use with recording devices such as the legendary Revox tape deck. I/O stands for In/ Out, i.e. this is a module which makes Inputs and Outputs available. 2 I/O Module Re:source Installation The I/O plug-in card has the most modern technology on it and should be handled with care. Before you start to install the card, the M51 must be switched off and the power plug must be removed from the power socket. Any plug position can be selected for the card, with the exception of Slots 3 and 7 which are reserved for the DVD and 5.1 Decoder cards respectively. Loosen the two screws with the TORX screwdriver supplied and remove the slot blanking plate. To be on the safe side, you should discharge any static from yourself by touching an earthed metal object such as a radiator. Remove the I/O module from its packaging and insert it into the slot position, using the two tracks within the M51 to guide it into position. The lettering on the card must be at the top. Just before the card is fully inserted, you will feel a certain mechanical resistance as the card meets the M51 contact strip. Push the card fully home by pushing in the area where the 2 screw holes are located and fix it in place with the two screws. All further steps needed to integrate the new module into the M51 will be carried out automatically next time the unit is switched on. Before removing the I/O module from its packaging, make sure that you are not charged with any static electricity. This could cause a damaging power discharge when you touch the module. 3 I/O Module Re:source Connections REVOX L AUX R Line inputs You will find the 3 AUX inputs AUX-1, AUX-2, AUX-3 on the connection side of the I/O module. AUX-1 can be defined as a Line or Phono input. The factory setting is Line input. This input, along with AUX-2 and AUX-3 can be used for the connection of devices such as a CD player, an external tuner or the audio output from a satellite receiver. IN 1 2 3 REC - REC - OUT A n a l o g I / O 1.551.081.00 Next to these, there is REC-IN, a further input which can be used for recording devices such as cassette or tape decks. As the analogue music signal from a cassette desk doesn't differ from that from a CD player, other devices can also be connected to the REC-IN input. Line input The analogue outputs of the following devices can be connected to a line input: Tuner, CD player, MiniDisc player, Cassette deck (Play), Picture disc player, DAT player, Tape deck, audio signals from TV, Satellite receiver, Game consoles. 4 I/O Module Re:source Phono input A special feature of the M51s I/O module is the ability to configure AUX-1 as a phono input. By setting DIP switches on the board, the AUX-1 input can be configured to meet the requirements of the phono playback system. There are three options: AUX-1 AUX-1 AUX-1 Line input MM Phono MC Phono Important Before starting work, switch the M51 off and remove the power plug from the power socket. Remove the two screws with the TORX screwdriver supplied and screw one of the Torx screws into the threaded hole on the top right of the I/O card. The I/O module releases itself from the M51 as you do this and can then be removed. It is best to set the switches before installing the card in the M51. If the card is already installed, you should proceed as follows: Note: Phono earth There is a knurled screw in the accessories kit supplied with the M51. If you are connecting a record deck, this screw should be used to replace the lower of the two screws on the I/O module. The turntable system can now be earthed through this knurled screw to the housing of the M51 which ensures hum-free vinyl enjoyment. 5 I/O Module Re:source The I/O plug-in card This graphic shows a schematic plan of the card, highlighting the position of the two switch blocks: Switches Cinch sockets I/O plug-in card The upper and lower switch blocks define the left and the right channel of AUX-1 respectively. For this reason, they must always have the same switch settings. The following switch settings should be used for the different input sources. The best thing to use for positioning the switches is a stylus or a small screw driver. 6 I/O Module Re:source AUX-1 as Line input REC-OUT output The REC-OUT output is used with recording devices such as cassette or tape decks. The REC-OUT output should be connected to the input socket of the recording device. (Factory setting) Input for CD player, external Tuner etc. AUX-1 as MM Phono Input for phonograph with MM cartridge system. AUX-1 as MC Phono Input for phonograph with MC cartridge system. Note As soon as the Line input AUX1 is configured as Phono input, this will be automatically shown in the source menu of the M51 with the new source name Phono. 7 I/O Module Re:source Connection assignments REVOX L AUX R 1 AUX-1: configurable as: Line input, MM or MC Phono AUX-2: Line input AUX-3: Line input IN 2 3 REC - REC-IN Line input for recording devices REC-OUT Line output for recording devices REC OUT A n a l o g I / O 1.551.081.00 The five large buttons on the front of the M51 are shown as Setup Source Amplifier Power Disc in the following chapters. 8 I/O Module Re:source Select input source The various sources are selected through the SOURCE menu. Press the Source button on the M51 and the following menu field appears: Select Record source If you want to make a recording to a device such as a cassette deck, you need to tell the M51 which source should be recorded from.
