1. Basic information 1.1 Mechanical construction & supply The case is fully made of aluminium. The audio-connectors are all gold plated to minimize electrical losses and provide long lasting perfect contacts. The PA3.2's power supply consists of an oversized toroidal transformer with minimized magnetic stray field and 10.000 µF of capacitance. In the A3.2 / A5.2 a switch mode power supply delivers clean, hum-free electrical energy for the analogue sections of the preamplifier.
1.5 Phono (option) The phono pcb is also installed in a slot in the rear panel of the unit. You can connect MC pickups as well as MM-types. The phono pcb is very versatile and allows individual setting of cartridge type, cartridge load and gain. The RIAA-equalization uses precise film capacitors and has a built in subsonic filter. So it works well with most of all cartridges on the market. 1.6 D/A-converter (option) The optional D/A-converter can also be plugged into a slot from the rear panel.

2.4 Insertion and removal of plug-in cards CAUTION: Before installing or removing cards ensure that the power plug is disconnected. Printed circuit boards are never to be installed or removed with the unit switched on. If you are inexperienced in working with electrical appliances it is recommended that you request your dealer to install the plug–in cards. We offer three plug in cards: A tuner card and a phono input and a digital input.
2.5 Setting of the phono card (option) To ensure that the phono card works in an optimal way, it must be set according to the requirements of the cartridge. Please refer to the operating manual / technical data of your cartridge to find out the correct settings. The setting is done by switches on the pcb. The upper switches are for the right channel, the lower for the left channel. The switches for both channels must be set identically.
2.6 Installation and cooling The unit can become hot depending on demanded output power and 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, this can heat up the unit. 2.7 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.
2.12 Connecting subwoofers 2.12.1 Active subwoofers without filters If you use an active subwoofer (with built in power amplifier), simply connect it's input to the proc out (21) and adjust the bass level at the subwoofer. If the subwoofer has a trigger input, connect it to the trigger output (26). 2.12.2 Active subwoofers with built in filters Most active subwoofers have a built in frequency divider network.
2.17 Headphones / front input 2.17.1 Headphones Plug the 3.3 mm headphones plug to the headphone jack (11). The loudspeaker and preamp outputs will mute automatically when the plug is in. 2.17.2 Front input The 3.5 mm jack in the front panel (11) can be configured as an additional input (see 4.13). You can use it then for easy connection of a music player. NOTE: the front input is connected in parallel to the rear input IN5. The inputs are naturally decoupled from each other.
3. Basic operation 3.1 First connection to mains When the amplifier is connected to mains and switched on for the first time the it 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. In the on state the display (4) lights up and the LED (3) is off.
3.5 Tuner (option) The tuner can be selected using the program selector (2). The basic functions of the tuner can then be accessed by the buttons right under the display (5 - 9). For more sophisticated functions see chapter 4. 3.5.1 Tuning Depending on the selected mode (manual / auto, see 4.2) the most right buttons (8, 9) under the display (4) 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.
4. Menu system The PA3.2 / A3.2 / A5.2 offer a lot of custom specific settings in their menu system. To enter the menu just tip on the button MENU (7). 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 (5, 6). The setting is done using the buttons VALUE (8, 9). Depending on the actual source the menu system offers the following settings: 4.
4.9 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.
5. Remote control The main functions of the can be controlled by the RC3: ON/OFF, Volume control, source and station select. The RC3 works up to distances of 7 meters. For best function point with the RC3 to the front panel of your hifi set. If the hi-fi set doesn’t react or reacts only over short distances, the batteries of the RC3 must be changed. Changing batteries RC3 Bottom view Unscrew the 6 marked screws (CAUTION, do NOT unscrew the 2 unmarked screws in the middle).
8.

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 (9). While holding that key switch the unit on (power button (1)). The display now will show "**personal setup***". Release the button (9) and the unit is in personal setup mode. When the personal setup is active you can select the desired function using the buttons ITEM (5, 6).
10.1.6 FM auto store (only if tuner installed) 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 (5).
