Introduction Congratulations on your decision to become the proud owner of this Plinius Hautonga Integrated Amplifier. This manual has been prepared to help you understand the operation of your amplifier, and to provide information about its design and the variety of ways it may be used. We have designed and manufactured this amplifier to reproduce your favourite music faithfully and accurately.
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.
Unpacking Open the box from the top and remove the accessories from the foam end caps. You may now proceed to lift the unit from the box, Once the unit is removed you can proceed with the removal of the foam end caps. These caps are designed to fit on the front and back of the unit for maximum protection. Retain the packaging for future transportation of this unit.
Care & Maintenance With simple care and maintenance your Plinius product can be kept looking and operating like new for many years to come. MAINTAINING THE CONNECTORS Exposed connectors such as the RCA connectors will be subject to environmental factors, and over time the surface may degrade. This can be greatly reduced by fitting readily available ‘RCA caps’ to reduce the effects of environmental elements on the RCA connectors. These RCA caps or RCA shorting caps can also provide sonic benefits.
Precautions PLEASE TAKE SPECIAL NOTE OF THE FOLLOWING PRECAUTIONS BEFORE OPERATING YOUR NEW AMPLIFIER. The Plinius Hautonga Integrated Amplifier can deliver in excess of 200 watts into 8 ohms. This amplifier is also capable of a very large peak current delivery. The Plinius Hautonga Integrated Amplifier operates in Class AB. It is capable of generating heat that could have an adverse effect on other electronic equipment, furniture, etc.
Front Panel Functions The front of the Plinius Hautonga Integrated Amplifier incorporates all the facilities you will require on a daily basis. 5 1 4 2 3 1. DISPLAY LED The blue LED on the front panel indicates the mode of operation. When first switched on the unit will go into standby and the display LED will vary in brightness. When the unit is taken out of standby and is ready for use, the LED will remain lit. Whenever mute or a remote volume button is pressed, the LED will dim. 2.
Rear Panel Functions This panel incorporates all terminals for connecting the input signals from your CD player, tuner, etc and the outputs to the loudspeakers and mains supply. Please remember that your Plinius Hautonga Integrated Amplifier is a high quality electronic instrument capable of an exceptional level of performance. Be sure that you understand your system’s requirements fully before you make any connection to this amplifier. 5 6 7 1 8 2 8 2 9 4 10 13 12 3 11 1.
4. INPUT SELECTION SWITCH This switch directly above the ‘CD XLR’ input is used to select the pair of CD input sockets required as described above. Towards the RIGHT channel selects the CD RCA input connections, while towards the LEFT channel selects CD XLR input. 5. HT BYPASS INPUT This input is for use specifically with home theatre processors. In some circumstances you may wish to use the power amplifier of the Hautonga Integrated as the front two channels of a surround or home theatre environment.
. MAINS POWER CORD IEC SOCKET This connector is where the mains supply cable from your wall connects to the amplifier. You will notice that a fuse holder is mounted within this connection, and it holds a mains fuse to provide surge and overload protection for your amplifier. 12. RAIL FUSES These tubular fuse holders house the positive and negative rail protection fuses. Depress and turn anti-clockwise to open. An LED is fitted next to each fuse holder and will illuminate to indicate a blown fuse. 13.
Remote Control Functions The Plinius Hautonga Integrated Amplifier features a full function remote to control all settings and configurations of the amplifier as well as complete controls for operating your Plinius CD player. INTEGRATED AMPLIFIER REMOTE FUNCTIONS: 1. STANDBY Standby is used to put the unit into a low power mode. This 1 2 disconnects the outputs of the Integrated Amplifier and turns off the white display LED’s.
6. MUTE Pressing this button toggles the Hautonga Integrated Amplifier in and out of mute. CD PLAYER REMOTE FUNCTIONS: 7. 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. It does not repeat one track only, but will repeat the entire contents on the CD. 8. DISPLAY This function enables you to quickly adjust the display brightness.
Installation & Operation WARNING: RISK OF ELECTRIC SHOCK This amplifier operates at hazardous voltage levels. We recommend that any work requiring removal of the lid be referred to a suitably qualified and experienced service technician. DO NOT place this amplifier in any position where liquids or any foreign material may accidentally enter it. PLEASE READ & UNDERSTAND THE PRECAUTIONS WITHIN THIS MANUAL FOR PLACEMENT & OPERATION OF THIS PRODUCT.
LOUDSPEAKER OUTPUTS The connection of your loudspeakers to the output posts of the Hautonga Integrated Amplifier must be made by an ‘instructed person’ with suitable ready made loudspeaker cables only. Connect your left loudspeaker (ie. the one on your left when seated in your normal listening position) to the left output terminals. Ensure the terminals on the amplifier are connected to the loudspeaker terminals Red positive (+) to Red positive (+) and Black negative (–) to Black negative (–).
USING HT BYPASS INPUT The Hautonga Integrated Amplifier features a home theatre input to bypass the preamplifier stage when used in home theatre or multimedia installations. When HT Bypass is selected, the signal will pass from the HT Bypass input directly to the Hautonga Integrated power amplifiers.
WARM-UP PERIOD You will find that the Hautonga Integrated Amplifier will become noticeably ‘purer’ in sound after being on for a period of time. We usually recommend waiting at least 24 hours before expecting the best quality of sound reproduction from your amplifier. Also, as the Hautonga Integrated Amplifier uses very little power while on, we suggest leaving the unit turned on so that it will always be at its sonic best.
Product Features REMOTE CONTROL Provided with your Hautonga Integrated Amplifier is a 16 function remote control. Two AAA batteries power the remote, and these are replaced by removing the two screws on the base of the remote that hold the battery compartment in place. The bottom end of the remote is now free to slide out for access to the batteries. Replace the two batteries, taking care to refit the new ones with correct polarity.
IMPORTANT: DO NOT FIT A FUSE WITH A HIGHER RATING. In the unusual event that this fuse should blow, you must first establish the cause of this failure (such as power surges, damaged mains cable, etc) before replacing the fuse with one of the same rating and type. Should the amplifier continue to suffer mains fuse failure, contact your Plinius dealer. OVER TEMPERATURE PROTECTION The Hautonga Integrated Amplifier is fitted with an auto-reset thermal sensor.
Loudspeaker Selection Your Plinius Hautonga 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. You may find loudspeaker specifications confusing or misleading, so you should discuss this with your audio dealer prior to purchase.
Troubleshooting NO SOUND FROM THE UNIT If the unit is not reproducing audio take the following steps: Check the source is correctly connected to an appropriate input on the unit. Refer to the Installation & Operation section on page 13. Check the source is playing, and not paused or muted. If it has adjustable volume, check this is at the usual output level. Check the unit is set to select the correct source input. Adjust the source selector for the correct source component.
