  • Page 9: Front Panel Functions

    Front Panel Functions The front of the Plinius Kiokio Power Amplifier incorporates all the facilities you will require on a daily basis. 1. POWER LED An LED in the centre of the front panel indicates the power is on. When first switched on, the display will vary in brightness until the initialisation sequence is completed, after which the LED remains lit.

  • Page 10: Rear Panel Functions

    1. INPUT TERMINALS Input terminals for your Plinius Kiokio Power Amplifier are easily accessible and fitted near the top centre area of the rear panel. RCA INPUTS: These standard RCA terminals are for use with unbalanced signals from most signal sources such as audio preamplifiers.
  • Page 11 The Amplifier Configuration Selector (ACS) is a unique switching method that exploits all of the operational features of your Plinius Kiokio Power Amplifier. By using this switch it is possible to operate your amplifier with either balanced or unbalanced signals.
  • Page 12 Plinius Kiokio has remote trigger terminals fitted to the rear panel. By connecting a processor with a remote trigger signal to these terminals, the Kiokio can be put in and out of Standby by the processor to which it is connected. When in Standby the amplifier draws less current and will operate at minimum temperature.

  • Page 13: Installation & Operation

    FOR PLACEMENT & OPERATION OF THIS PRODUCT. CONNECTIONS Connections to your Plinius Kiokio should be made in the same order as they are listed in this section. DO NOT attempt to connect your Plinius Kiokio until you have read and fully understood these instructions. Although these instructions refer to the connection of a preamplifi er, the Kiokio can also be safely installed into multimedia systems by following the same installation guidelines.
  • Page 14 Bi-wiring uses two pairs of loudspeaker cables for each channel loudspeaker. You will notice that the rear panel of your Plinius Kiokio has two pairs of output terminals for this purpose. Be sure to follow correct practises for stereo and mono configurations when using bi-wiring.
  • Page 15 Check the wall outlet is switched OFF, then connect the local mains plug end of the lead to the wall outlet. Check the Kiokio is switched OFF, and connect the IEC end of the cable to the IEC socket at the back of the Kiokio. With the cord fully connected, switch the wall outlet ON.

  • Page 16: Product Features

    Product Features ERROR DETECTION The Plinius Kiokio Power Amplifier has in-built error detection. This will function under the following conditions: • When the amplifier is overdriven/clipped • If any internal fuse is damaged. Should either of these circumstances arise the amplifier will disconnect both channels and mute the input.
  • Page 17 TEMPERATURE MONITORING The Plinius Kiokio Amplifier has temperature-monitoring circuitry. When the amplifier reaches an internal temperature of 65 degrees C, the amplifier will be shut down until the temperature returns to normal. When the temperature has exceeded the set point, the power LED will turn off and the mute LED will flash on and off quickly.

  • Page 18: Loudspeaker Selection

    Loudspeaker Selection Your Plinius Kiokio Power Amplifier is designed for use with high fidelity loudspeakers. It should not be used to operate any other type of appliance or equipment. Be certain that your loudspeakers can handle most of the rated output power of this amplifier.

  • Page 19: Troubleshooting

    NOTE: If the unit immediately or repeatedly suffers rail fuse failure, there may be a major problem and you should contact your Plinius dealer. POWER FAILURE The unit may have suffered mains fuse failure or be in thermal overload protection mode.
