1. Basic information 1.1 Mechanical construction The case is fully made of aluminium. The audio-connectors are all gold plated to minimize electrical losses and provide long lasting perfect contacts. 1.2 Power supply A switch mode power supply delivers clean, hum-free electrical energy for the digital and analogue sections of D/A-converter and the preamplifier. All voltages are additionally buffered by large capacitors directly in the circuitry where they are needed.
1.5 CD player / D/A- converter C8 and C9 are equipped with upsampling circuitry and highly precise a/d converters. The theory of function will be described in the following text. If You are not interested in technical details, skip these chapters and simply listen to the music. You will discover Your CD collection anew! And that is what we want to achieve. Because application of new technologies is not just a gimmick but offers audible and measurable advantages to the listener. 1.5.
1.5.3 Filtering If a digital signal is converted to analogue the analogue signal contains not only the original signal, but as well it’s mirror image which lies in the frequency domain beyond one half of the sampling frequency. This mirror image (aliasing) can cause unwanted interference with the original signal and thus must be filtered out before passing the signal to the amplifier.
2. Control & operating elements 2.1.1 INSPIRATION C8 The numbers in the drawings below mark the control elements. They refer to the numbers in the text, where the operation of the unit is described.
2. Control & operating elements 2.1.2 EVOLUTION C9 The numbers in the drawings below mark the control elements. They refer to the numbers in the text, where the operation of the unit is described.
2.3 Installation and cooling The unit can become hot depending on demanded output power / environmental temperature. Therefore it is important, that the cooling air can flow unhinderedly into the air inlet in the bottom and flow out through the holes in the rear panel. Direct exposure to sunlight is not recommended because this will heat up the unit. 2.4 Connection to mains Connect the unit to the mains outlet by using the power cord which is (in some countries) delivered together with the unit.
2.7 Connecting a recorder Connect the recorder’s output to one of the inputs (18). The inputs of the recorder must be connected to the fixed level outputs (23). 2.8 Connecting processors / equalizers Connect the processor’s outputs to the inputs main in (25). The inputs of the processor must be connected to the outputs pre out (24). Additionally You must activate the processor loop (see 4.13) 2.
3. Basic operation 3.1 First operation / self test In case the C8/C9 was not connected to mains a self test will be performed when it is switched on by mains switch (34) for the first time. The unit checks it’s configuration and if all installed components work properly. The procedure is shown in the display. After that the unit will switch to stand by. 3.2 Switching on / standby Using the button power (1) You can switch between on (operate) and stand by.
3.5 Tuner (if built in) The basic functions of the tuner can be accessed by the buttons right under the display (4 – 8). For more sophisticated functions see chapter 4.4 to 4.8 3.5.1 Tuning Depending on the selected mode (manual / auto, see 4.2) the most right buttons (7, 8) under the display (3) are named AUT or MAN . In AUT-mode a tip on one of the buttons lets the tuner automatically seek the next upper or lower station.
3.6 CD player The basic functions of the CD player can be accessed by the buttons right under the display (4 – 8). For more sophisticated functions see chapter 4. 3.6.1 Insert / eject Insert a CD The C8 / C9 have a slot-in CD drive. Insert the CD (coverside up) and push slightly. The drive will now automatically draw the disc inside. After that the player reads the TOC and shows it on the display.
3.6.4 Programming an individual playlist If a disc is inside the player You can program Your individual playing sequence as follows: Hold the button "MENU" (6) down for more than 2 seconds to enter the playlist-menu. The display shows on the left side the actual title ("TRCK"), below the playing time of this title ("TIME"). Pressing the buttons SELECT (4, 5) allows You to select a title. Pressing "ADD" (6) adds the selected title to the playlist.
4. Menu system The C8/C9 offer a lot of custom specific settings in their menu system. To enter the menu just tip on the button MENU (6). The button now changes to EXIT. A second tip on this button leads You to the normal operating mode. When the menu system is active You can select the desired function using the buttons ITEM (4, 5). The setting is done using the buttons VALUE (7, 8). Depending on the actual source the menu system offers the following settings: 4.
4.10 Loudness If You listen to music at low levels, You often recognize that bass and treble reproduction are weak. This is because the human ear is not sensitive to bass and treble at low sound levels. To compensate this You can use the parametric loudness function of the C6m. This function will increase bass and treble levels when You decrease the volume. When the volume is increased the frequency response will be more and more flat and remain linear at high volume levels.
6. Cleaning Use a soft cloth and normal glass cleansing fluid. CAUTION: Make sure that no fluid comes into the unit. Do not use scouring cleaners. They may damage the surface. 7. If something doesn’t work....... Some putative defects are often caused by mistakes in operation. Sometimes other units connected to the amplifier can cause problems. Therefore please read the following tips before You consult Your dealer or us. 1.
8. Conditions of warranty (EC only) If despite expectations a defect occurs that cannot be repaired by yourself or your dealer, we undertake the repair of your unit free of charge for up to three years from date of purchase. The warranty covers the costs of material and working time, transport costs are to be borne by the owner. Provisions for this warranty are: • The unit must have been purchased from an authorized dealer. Equipment from other sources will not be repaired, not even at charge.

10 Appendix 10.1 Personal setup Several settings can be done in the personal setup To access the personal setup switch the unit to standby (power button (1)). Then press and hold the most right key under the display (8). While holding that key switch the unit on (power button (2)). The display now will show "**personal setup***". Release the button (8) and the unit is in personal setup mode. When the personal setup is active you can select the desired function using the buttons ITEM (4, 5).
10.1.6 FM auto store This function is useful when storing a large quantity of stations from cable. Please note that the stations are stored including the actual tuner setting (see 4.1 - 4.5). For cable we recommend: RDS-display = name, scanmode = auto, 2-ch mode = stereo, bandwidth = narrow, sensitivity = local. Once the tuner parameters are set in the desired way enter the personal setup and select "FM auto store". Then press the button START (4).
