Installation
Mains voltage
Your products must be earthed using the power cord supplied.
Audio input connections
The audio signal input is to connect up to two audio sources using XLR inlet and/or RCA inlet.
The XLR inlet permits the connection of a source with balanced signal and uses standard wiring instructions:
Pin 1 = Ground (shield)
Pin 2 = In phase voltage ("hot")
Pin 3= Out-of-phase voltage ("cold")
The RCA inlet permits the connection of a source with unbalanced signal. It's common to link the out-of-phase
voltage (Pin 3) to the ground (Pin 1). This connection is generally made at wire level.
Warning
In order to allow you to plug up to two audio sources to the monitors using RCA and XLR inlets, please
note that both inputs will remains on. If you want to take benefit of this feature by plugging two audio
sources, make sure only one audio source is on to avoid any unwanted interaction or sound from the
second audio source.
AUTO-STANDBY MODE
The ALPHA monitors are equipped with an "Auto Standby" mode. When switching the monitors on, the "Standby"
mode is active. To deactivate it, send audio signal to monitors by slowly leveling up the output level of the audio
source. After about 30 minutes without receiving audio signal, the monitors will automaticaly go to "Standby" mode.
In "Standby" mode, the power consumption is less than 0,5W.
Positioning
The ALPHA loudspeakers are near field monitoring loudspeakers and should be positioned at a distance between
40cm and 3 meters from the listener, pointing towards the listening position. They can be sitting on the console
top or placed on appropriate stands. In any way, it is recommended that the tweeter is at a height from the floor
approximately equivalent to that of the listener's ears. If required, it can make sense to place the speakers upside
down so that the previous rule is better fulfilled. The ALPHA loudspeakers must be placed vertically pointing towards
the listener (fig. D, E).
