Connecting PLATINUM

Note:

  • The mounted Ortofon 2M RED cartridge is a MM cartridge, so please set your audio system to MM (not MC).
  • Make sure the audio system/amplifier you connected to PLATINUM is switched off and its volume set low.
  • Before turning on your audio system and PLATINUM, make sure all connections are made properly, and you choose the right preamplifier setting.
  • Failures in doing so may lead to loud hum noise which may damage your audio system or speakers.
  1. Connecting to an audio system/amplifier
  • Connect your audio system and PLATINUM by using the delivered RCA cable.

  • If your audio system has a built-in phono amplifier, there most probably will be a grounding terminal. Please screw the grounding cables on both sides: Your audio system and PLATINUM. As well plug the RCA plugs into the phono input of your audio system and the output of PLATINUM.
    Note:

  • The ground terminal of PLATINUM is not a safe ground connection.

  • Depending on the amplifier, connecting the ground terminal might have the reverse effect of increasing noise. In this case, it is not necessary to connect the ground terminal.

  • It is not recommended to connect PLATINUM’s phono ground to MAESTRO’s phono ground plate.

  • If your audio system has no phono input, use a free Aux-in RCA input.

  • The white plug is for the left channel, and the red plug is for the right channel.

2. Setting pre-amplifier selector switch  Switch the pre-amplifier switch on the back side of PLATINUM according to the features of your audio system/amplifier PLATINUM is connected to:

  • Set the switch to the OFF position. If your audio system/amplifier has a PHONO input jack, PLATINUM can be connected directly to it, bypassing it’s built-in preamplifier by switching it OFF.

  • Set the switch to the ON position. If your audio system/amplifier has no phono input, you can use the built-in pre-amplifier of PLATINUM by switching it ON.

3. Connecting the AC adapter

  • After completing all other connections, connect the included AC adapter to the DC input socket.

  • Insert the power supply into an AC inlet socket.
