User manual MICROMEGA CD-30

[. . . ] If for aesthetic or ease of use reasons, you choose to stack the units, it is imperative that you place your amplifier on the top. We recommend that you provide a space of at least 30cm above your amplifier in order to ensure adequate ventilation. CONNECTIONS The display indicates: - On the left side the selected source. - In some cases the status of the unit (Balance, Headphone…). SELECTION (< INPUT SELECT >) Having verified that the mains voltage indicated on the rear of the unit corresponds to the local power supply mains voltage and that the ON/OFF switch is on OFF position, connect the mains leads provided to the rear the unit and to the wall socket. Connect the Stereo Interconnect cables from the rear of all your sources to the corresponding inputs on your amplifier. [. . . ] It is important to use quality speaker cable to get the maximum out of your amplifier. The selection of inputs is made via the < INPUT SELECT > keys. - In order to select your choice of input use successive depressions of the key. The display will indicate the name of the selected source from the following list: PHO – AN1 – AN2 – AN3 – AN4 – iPod. VOLUME The setup of volume is achieved with the rotary control located in the centre of the front panel. The display will indicate a level between -80dB and 0 dB. Note: The rotary control allows access to different speeds of volume adjustment. This will allow you to move to the desired volume with great ease. LISTENING TO HEADPHONES (HEADPHONE) 2. 1 MODE Your amplifier is equipped with a SUB-OUT output. The level of this output is set by the main volume control of the unit. If you have an audio-video processor like AP-180, a SUB-IN input is available just above the SUB-OUT connector. Connect the SUB-OUT of your audio-video processor to the SUB-IN of your amplifier. When in Stereo mode your amplifier will control the level of your active subwoofer while when in PRO-ON mode the audio-video processor will take control over your active subwoofer. This unique feature allows a complete different subwoofer set-up between stereo mode and home cinema mode. ANALOG INPUTS NAMES The four analog inputs AN1, AN2, AN3, et AN4 can be renamed using the internal name library of the microcontroller of your amplifier. On another end, as soon as your amplifier will have detected the presence of an iPod or an iPhone, it will automatically select the iDok analog input and the front panel iPod input will be disconnected. CONTROL VIA RS-232INTERFACE It is necessary to confirm your choice by a second depression on the MON/PRO key. If you go to standby mode (Pressure on the STANDBY key) or if a power failure happens while your unit was set in PRO ON mode, the unit will revert automatically into PRO ON mode when going out of standby or when power comes back again. MUTING (MUTE) - Press this key when you want to put the amplifier into MUTE mode. The display will indicate: - Press again MUTE to resume listening BALANCE (MUTE) - Press the MUTE key for a period of 2 seconds. The display will indicate: - Set the desired balance using the central rotary control. - If you turn clockwise, the display will show R1, R2…R6 indicating that the right speaker level will be increased by 1, 2…6 dB. - If you turn counter clockwise, the display will show L1, L2…L6 indicating that the left speaker level will be increased by 1, 2…6 dB. If you had offset the balance, the display will indicate it by inserting a balance logo : Your amplifier is equipped with a DB9 female connector to control it via RS232 interface. It accepts the following format: Baud Rate Data bits Parity bit Stop bits Flow control : : : : : 19200 Bauds 8 None 1 None PRE-OUT OUTPUTS Your amplifier is fitted with PRE-OUT outputs to allow you to use an external power amplifier. You will find complete instructions concerning this interface in the separate RS232 manual.
