CONNECTION OF ONE OR MORE POWER AMPLIFIERS
The SA-96 preamplifier has two stereo preamplifier outputs with RCA connectors for the connection to the main amplifier(s). The stereo audio signal (R, L) is output on each of the two RCA socket pairs. So you have the option to connect one or two stereo main amplifiers, up to four mono main amplifiers or one mul- tichannel main amplifier to supply up to four loudspeakers. This also allows you to operate either more than two loudspeakers or two loudspeakers in Bi-amping (e.g. with two stereo main amplifiers). The main amplifiers supply the system’s loudspeakers and the loudspeakers are connected to the outputs of these. Connect the required output sockets in the field “OUTPUT” with the RCA input sockets of the main ampli- fier channels (often marked as “INPUT” or “POWER AMP IN”). For this you need RCA cables. The follo- wing drawing shows the connection of two mono main amplifiers (e.g. Vincent SP-996).

If main amplifier channels are to be connected for two pairs of loudspeakers, please additionally use the second stereo pair of the preamplifier outputs.
If there are four main amplifier channels available and the loudspeakers support this, it is also possible to operate one pair of loudspeakers in “Bi-amping”. The loudspeakers used must be suitable for this. You will recognise this by the double connection of the loudspeaker terminal whose bridges can be removed for ope- ration in Bi-amping or Bi-wiring. Your specialist dealer will advise you of this on request.
CONNECTING HEADPHONES
A set of headphones equipped with a 6.3 mm jack can be plugged into the “PHONES” socket (8) on the front of the appliance.
All headphones with an impedance of between 32 Ohm and 600 Ohm may be used. Unsuitable head- phones with too low impedance may damage the amplifier or produce such unexpectedly loud volume that your hearing may be damaged. The volume should be reduced for safety reasons before a set of phones is connected. The output signals of the preamplifier are not affected by plugging-in headphones.
CONNECTIONS FOR THE STANDBY CONTROL
(POWER CONTROL)
Many AV-Systems consist of a multitude of individual components. To avoid the necessity of switching them on and off before and after every use, many manufacturers have equipped their devices with what is known as “POWER CONTROL” circuit or “TRIGGER”. This kind of remote-controlled standby circuit is used primarily for preamplifier and power amplifiers. To employ these functions, direct or indirect cable connections must be made between the preamplifier (or integrated amplifier) and all the devices which support this function. The “POWER CONTROL” function operates in such a way that each switching on or off of one device in the system (usually the preamplifier) automatically brings about the switching on or off of all the connected devices which support this function. Please keep in mind that all devices which respond to the power control are not disconnected from the mains network when switched off. They are set to a standby state instead. For connecting cables, two-core cables with 3.5 mm jack plugs (mono) are used. For each connection between two devices one of those cables is needed.
If the whole system is to be turned on and off with the SA-96 preamplifier, the cable connections for the power control described below must be made correctly. If you don't wish to use this function or if the other components do not support it, all you have to do is leave out these cable connections.
The SA-96 has two output connections for the power control. Two HiFi components that are able to react to the power control signal can be connected directly to the preamplifier's power control outputs. If more than two devices, which can be controlled, are to be connected, then it is necessary, to make the power control connection between the preamplifier and these further devices through the outputs of the two devices which are connected directly. For that reason, every HiFi component that accepts power control signals is also equipped with a power control output. Thus, in theory it is possible to provide an infinite number of HiFi com- ponents with the power control signal. This approach, to loop a signal through a chain of components, is commonly referred to as “daisy chaining”.

Many devices which can be controlled by a switching signal (not preamplifiers or integrated amplifiers), have two terminals which do not differentiate between input and output. In this case either of the two can be selected.
“POWER CONTROL” sockets of preamplifiers or integrated amplifiers must not be interconnec- ted! All receiving devices must not be connected to more than one preamplifier or integrated amplifier (directly or indirectly)!
