53. INSTALLATION3.1. Location and assemblyThe CA40 is suitable for installation on a wall or under a surface (table, shelf, cupboard,etc.), thanks to its design and layout of its connectors, controls and LED indicator lights.3.2. Mains connectionThe amplifier is powered by alternating current through its external power source: 100-240VAC and 50-60 Hz.This apparatus must be earthed through its mains cable (earth resistance, Rg = 30 , orlower). The atmosphere should be as dry and dust free as possible. Do not expose the unit to rainor water splashes. Do not place liquid containers or incandescent objects like candles on top ofthe unit.Should any work or connection / disconnection task be done, always disconnect the unitfrom the mains supply. There are no elements that can be manipulated by the userinside the amplifier.To avoid buzzing, do not allow the power cable to intertwine with the shielded cablesthat transport the audio signal.3.3. Audio input connectionsThe CA40 accepts two types of signals in its input channels: Microphone (MIC): has a balanced Euroblock or jack type connection, ready toaccept a signal level between -20dBV y –50dBV, with adjustable sensitivity withthe ADJ controlNOTE: the microphone input has a phantom power supply to powercondenser microphones, activated by internal bridge (see section 10.CONFIGURATION DIAGRAM). Line signals (LINE 1, LINE 2): they have unbalanced minijack or double RCAtype stereo connections. They are prepared for input of between -6dBV and0dBV, with input sensitivity that can be adjusted by internal port (see section 10.CONFIGURATION DIAGRAM). You can connect signals from CD players,radio tuners, mixing consoles, media players, the audio outputs of PCs andtablets, etc. to these connections.NOTE: Turntables CANNOT BE CONNECTED directly to this device because none ofthe inputs have an RIAA preamp.The CA40 has the following operating modes according to the input sources selectedas active: LINE 1: only LINE 1 input is sent to the mix bus to be amplified and delivered to the Land R OUT outputs LINE 2: only LINE 2 is sent to the mix bus to be amplified and delivered to the L and ROUT outputs MIC: only microphone (MIC) input is sent to the mix bus to be amplified and delivered tothe OUT L and R outputs
