Symbols and Notes N THIS MANUAL A LIGHTNING SYMBOL WITHIN A TRIANGLE WARNS YOU ABOUT THE POTENTIAL FOR DANGEROUS ELECTRICAL SHOCKS – WHICH CAN ALSO OCCUR EVEN AFTER THE MACHINE HAS BEEN DISCONNECTED FROM A POWER SOURCE. AN EXCLAMATION MARK (!) WITHIN A TRIANGLE IS INTENDED TO MAKE YOU AWARE OF IMPORTANT OPERATIONAL ADVICE AND/OR WARNINGS THAT MUST BE FOLLOWED. BE ESPECIALLY ATTENTIVE TO THESE AND ALWAYS FOLLOW THE ADVICE THEY GIVE.
Important Security Information Lightning: Before thunderstorms or other severe weather, disconnect the machine from wall power (but to avoid life threatening lightning strikes, not during a storm). Similarly, before any severe weather, disconnect all the power connections of other machines and antenna and phone/network cables which may be interconnected so that no lightning damage or overload results from such secondary connections.
Introduction M/S Stereophony Our ability to identify the direction and distance of a sound source is the essence of spatial hearing. The human ear can identify level and time differences from ear to ear very precisely and use that information to localize sound. At frequencies up to 1500 Hz the ear analyzes basically time differences to localize sound, while above this frequency it uses level differences.
Introduction M/S encoding is also used for VHF radio transmission. In this case, the Mid signal is sent with much higher energy. If the reception is not very good, a stereo receiver can switch to mono to retain the most important information. A mono receiver will always receive a mono compatible signal. Equally beneficial is M/S encoding when using „Joint Stereo“ compression with MP3. As long as there is almost no information in the side signal, the compression rate can be higher as with L/R encoding.

Rear Panel Connections Signal Connections Turn off the unit before connecting or disconnecting any cable or equipment to it. Otherwise you risk the possibility of damaging your ears or equipment. Input and Output Electronics The input and output electronics of the M/S Master possesses two very distinctive features: 1. Bridge circuits that keep the signal flow constant, regardless of malfunctioning equipment and power outages (power fail safety by relay hard bypasses). 2.
Rear Panel Connections XLR sockets All signal connections are made via balanced XLR connectors. Inputs are always female and accept male connectors; outputs are always male. All in all, a very comprehensible principle. Balanced connections It is impossible to exclude interferences when a single audio signal is transmitted. Shielding is effective against electric, but not against electromagnetic influences. Motors, transformers, and alternating current can always induce interferences.
Rear Panel Switches Voltage Selector VOLTAGE | FUSE 230V ~50Hz 315mA slow The rear panel VOLTAGE selector sets the local line voltage (115 V position: 110-120 volts/6o Hz, 230 V position: 220-240 volts/50 Hz). The diagram shows the correct switch position for 230 V power supply. 115V ~60Hz 630mA slow BEFORE you connect electrical power make sure that the VOLTAGE selector setting reflects the correct local power line voltage.
Operation Input settings Input settings Given that all productions are mixed differently, it is impossible to provide general recommendations regarding settings. By default, settings correspond to a passive M/S encoder without applying any processing, i.e. L/R stereo is encoded as M/S stereo and the rest of the M/S Master functions have no influence on the sound.
MID section Control Elements Mid MID: INSERT Use the INSERT switch to activate the insert point for the Mid channel. You can connect any mono processor, or a single channel of a stereo unit, to the insert jacks on the rear panel. As soon as you engage the INSERT switch, the connected units are integrated into the M/S Master processing path. To use the processors independently of the M/S Master, as well as for mono or L/R processing, disengage the ACTIVE switch of the M/S Master.
Control Elements -/+ FILTER –/+ -1 0 1 2 4 -7 -6 -5 -4 - 3 3 -2 5 6 -8 7 8 9 9 SIDE section FILTER The „-/+“ knob controls the only actual effect on the M/S Master: a shelving filter meant to boost or attenuate low and mid frequencies in the Side signal. The frequency range below the given cut-off frequency is equally boosted. Use the LOW RANGE push button next to it to set one of two possible cut-off frequencies, in order to define the frequency range to be processed (see the next section).
SIDE section Control Elements SIDE: INSERT Side Use the INSERT switch to activate the insert point for the Side channel. You can connect any mono processor, or a single channel of a stereo unit, to the insert jacks on the rear panel. As soon as you engage the INSERT switch, the connected units are integrated into the M/S Master processing path. To use the processors independently of the M/S Master, as well as for mono or L/R processing, disengage the ACTIVE switch of the M/S Master.
Control Elements OUT8PUT - -2 3 -15 -14 0 2 4 M PPM Use the OUTPUT control to attenuate the output signal up to -16 dB or boost it up to +4 dB, in order to match it to the following unit in the chain. The output level on the VU-meter is indicated in PPM mode. Before starting any processing, always set the OUTPUT control to 0 (around three o‘clock). That way you can read the Mid and Side signal levels on the VU-meter without the output setting having any influence on them.
Output & VU section -10 dB Control Elements PPM Use this push button to reduce 10 dB the sensitivity of the VU-meters. When the VU-meters‘ needle points at 0 db, it actually corresponds to -10 dBu and the maximum value is +15 dB. The sensitivity switch allows you to analyze very high level signals that would otherwise be beyond the range of a normal meter. ACTIVE VU ACTIVE Use the ACTIVE push button to switch on or off the processing electronics of the M/S Master.
Working with External Processors Compressor We will describe in detail the two most common types of processing units used: compressors (to process dynamics) and equalizers (to correct or shape signals based on frequency). You can obviously connect all sorts of processors to the inserts of the M/S Master: reverb and delay effects, a De-esser in the MID INSERT to reduce vocal sibilance, tube processors to add character to the sound... Whatever suits your needs.
Equalizer Working with External Processors Equalizer The possibilities that an equalizer provides when working with the Mid or Side signals correspond to the normal applications of an EQ, the full scope of which is beyond our purpose. Two of the most common functions of an EQ ought to be more than enough to illustrate the potential of using it as an INSERT: attenuation of low frequencies and boosting of high frequencies.
