All operational, technical and descriptive material in this publication is subject to change at any time without notice. For further product information or queries, please contact your Plinius dealer. Plinius products are designed and manufactured by Plinius Audio Limited, New Zealand. -
Page 3: Introduction
We have designed and manufactured this amplifier to reproduce your favourite music faithfully and accurately. With a little care and a full understanding of the operating recommendations in this manual, your Plinius Hiato Integrated Amplifier will provide years of high-quality, trouble-free performance. -
Page 4: Design Philosophy
Design Philosophy From a distance you can see that the design of the Plinius products is more than an applied styling exercise to the front panel. We have started from the ground up to produce a casing for our electronics that is unrivalled in its physical strength and visual simplicity. -
Page 5: Unpacking
Please ensure that the heat vents (slots in the base and lid) are not covered or restricted in any way. The Hiato Integrated Amplifier design incorporates a very high level of mechanical decoupling of the input and output. It can however still be influenced by acoustical feedback in the operating environment. -
Page 6: Care & Maintenance
SURFACE CLEANING From time to time you may wish to clean the surface of your Plinius equipment to remove dust, or any material build up from the atmosphere or on commonly used controls. Your Plinius product is made up of parts that have a hard anodised or a powder coat finish and will clean easily without being damaged. -
Page 7: Precautions
PLEASE TAKE SPECIAL NOTE OF THE FOLLOWING PRECAUTIONS BEFORE OPERATING YOUR NEW AMPLIFIER. • The Plinius Hiato Integrated Amplifier can deliver in excess of 300 watts into 8 ohms. This amplifier is also capable of a very large peak current delivery. •... -
Page 8: Front Panel Functions
Front Panel Functions The front of the Plinius Hiato Integrated Amplifier incorporates all the facilities you will require on a daily basis. 1. DISPLAY LED An LED on the front panel indicates that the power is on. When first switched on the unit will go into standby and the display LED will vary in brightness. - Page 9 The volume control is a motorised unit that will accurately convey the selected source signal to the line stage of the Plinius Hiato. When using the remote control to alter the volume level, briefly press the button to make small adjustments, or hold the button down to continuously adjust the volume.

PIN 1 to GND PIN 2 to +Signal PIN 3 to -Signal NOTE: Because of the way Plinius balanced inputs are configured it is not possible to connect to both XLR and RCA at the same time for use. 3. INPUT SELECTION SWITCH This switch, located with each of the CD, Line 1 and HT Bypass inputs, is used to select the pair of CD input sockets required as described above. - Page 11 This input is for use specifically with home theatre processors. In some circumstances you may wish to use the power amplifier of the Hiato as the front two channels of a surround or home theatre environment. The HT Bypass input can be used for this purpose, as any signal connected to these inputs can be sent directly to the power amplifier bypassing the preamplifier entirely.
- Page 12 This socket is for connecting to an external remote control sender. Some companies such as Xantech manufacture these devices to enable multi-room remote control. Please see your Plinius dealer for further advice. 13. GROUND LIFT SWITCH This switch allows the signal ground to be isolated from the chassis. In some installations a hum loop may exist due to duplicate ground paths from different equipment.

LED’s. It also switches the power amplifier to a low bias mode to reduce power consumption and still keep the circuitry active. This allows a minimum warm up period before the Hiato is at it’s sonic best. 2. DISPLAY The display button on the remote enables you to adjust the display brightness of the white LED’s. - Page 14 7. MUTE Pressing this button toggles the Hiato Integrated Amplifier in and out of mute. CD PLAYER REMOTE FUNCTIONS: 8. REPEAT The repeat LED on the front panel will illuminate once this button is pressed. The CD Player will play all tracks on the CD as normal, but then repeat all tracks from track 1 in an endless loop.

CONNECTED YOUR INPUT/OUTPUTS CORRECTLY FOR YOUR SYSTEM. CONNECTIONS Connections to your Plinius Hiato should be made in the same order as they are listed in this section. DO NOT attempt to connect your Plinius Hiato until you have read and fully understood these instructions. - Page 16 SOURCE COMPONENT INPUTS Connect your Source to the input of the Plinius Hiato using suitable single-ended RCA or Balanced XLR interconnect cables only. For RCA, make sure you connect the red coded cable to the red RIGHT RCA input, and the white (or black) cable to the white LEFT RCA input.
- Page 17 HT Bypass input will also go to BOTH the RCA and XLR pre out connectors. USING PRE OUT A preamplifier output is provided on the back of the Plinius Hiato. If you wish to use the Plinius Hiato as a pre-amp only, or to send signal to another amplifier, fit the...
- Page 18 Check the wall outlet is switched OFF, then connect the local mains plug end of the lead to the wall outlet. Check the Hiato is switched OFF, and connect the IEC end of the cable to the IEC socket at the back of the Hiato. With the cord fully connected, switch the wall outlet ON.

PHONO GAIN ADJUSTMENT The Hiato Phono input can also be set to one of four gain settings to suit your phono turntable specifications using the 2-way mini-switches labelled ‘GAIN’. These 2-way mini-switches allow the gain to be adjusted as low as 50dB, to suit high output Moving Magnet (MM) cartridges, or as high as 66dB for low output Moving Coil (MC) cartridges. - Page 20 ERROR DETECTION The Plinius Hiato Power Amplifier has in-built error detection. This will function when an amplifier channel is overdriven/clipped; Should this arise the amplifier will disconnect the output of both channels until the input signal level returns to normal. Whenever error detection is triggered, the power LED will flash on and off.

Page 21: Loudspeaker Selection
Loudspeaker Selection Your Plinius Hiato Integrated Amplifier is designed for use with high fidelity loudspeakers. It should not be used to operate with any other type of appliance or equipment. Be certain that your loudspeakers can handle most of the rated output power of this amplifier. -
