[. . . ] Housings should not be removed, in order to avoid the danger of an electric shock. Maintenance and repairs should only be carried out by qualified personnel. Installation and operation Please check the unit and accessories for any signs of transit damage, once you have unpacked it. Please read the operating instructions carefully before starting to use the unit. If the unit shows any signs of damage or has come into contact with any fluids should not be connected to a power supply. [. . . ] This means that as you increase the volume at the speakers, for example, the PRE OUT level is automatically changed at the same time. Application: You should select Floating Volume mode if, for example, and additional output device or an active subwoofer is connected, whose volume should also be controlled by the M219. This means that the M219 speaker output remains active. Fixed Volume: In this mode, the volume control and the M219 output devices are deactivated, i. e. the volume cannot be controlled by any wall-mounted or infrared remote control. Irrespective of whether it is addressed through the multiroom bus or a local input (Local IN 1 2 3), each source has a standard level, the so-called Line Level. Application: The Fixed Volume mode has been conceived principally for applications where digital REVOX speakers are to be connected to the M219 over a DLC2 interface.

This means that as soon as the voltage is present at IN, the M219 switches on automatically and selects the input LOCAL IN 1. When the voltage is removed from input IN, the M219 switches off again automatically, as long as no other source apart from LOCAL IN 1 was addressed. With DIL switch (3), you can define whether the volume control is handled by the M219 (Floating Volume) or the connected (TV) device (Fixed Volume). With Fixed Volume, the M219's volume control is deactivated and the audio signal at LOCAL IN 1 is transmitted with a fixed strength. In this way, volume control is carried out with the TV remote control. The volume control setting set by DIL switch 3 only has an effect on the local audio input LOCAL IN 1. LOCAL IN 1 Floating Volume Fixed Volume Application: DIL switch 3 Off On DIL position 3 3 Many devices output a voltage as soon as they are switched on. If you connect the voltage output of such a device with the IN voltage input on the M219 and the audio output with the local audio input LOCAL IN 1, the M219 will switch on automatically with the other device and transmit the sound. If your device doesn't have a voltage output, you can supply voltage to the input using a sensor-switch multiple socket outlet (Master/Slave socket outlet) and a normal plug-in power supply (5-24 V= / DC).

On a standard SCART socket, PIN 8 outputs the positive voltage (+) and PIN 4 or 14 is the earth (-). The principle of Master/Slave socket outlets With this type of socket outlets, the control device (the TV in the above example) is plugged into the master socket while all other devices are connected through the slave sockets. Connection to the IR receiver or the wall-mounted remote controller is made using a screwable Phoenix plug connector. REVOX recommends the use of a 3-core, screened cable* (microphone cable), where the screening is used as an earth. Please refer to the label for the correct cabling: GND A B VCC Front view of RJ11 Connector + IN - Positive feed - VCC IR Signal Data Earth GND the maximum number of IR receivers per M219 is 5. In this case, no further cable would be necessary if you added an additional display at a later stage. IR commands The M219 accepts all RC5 or RC6 commands and carries out those that are intended for it.
