Attention!
Risk of electric shock
Do not open
Do not expose to rain or moisture
The lightning flash with arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated «dangerous voltage» within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product.
The loudspeaker is supplied with the following elements (apart from this manual):
Please check that none of these items is missing, and remove all accessories from the box. To remove the loudspeaker from its box without damage, open the end flaps fully and bend them right back. Then remove the upper cushion and lift the loudspeaker out gently. Inspect the speaker for signs of any possible damage. In the unlikely event of this having occurred, please inform the carrier and supplier. It is a good practice to keep the packaging in case of future transportation.
We would like to give a word of warning about the high sound pressure levels that can be generated by these loudspeakers, especially in a 5.1 configuration. Because of their low levels of distortion, and the minimal fatigue incurred by the user, it is not always obvious to realize the actual sound pressure level while working. Please bear in mind that exposure to excessive levels over a sustained period of time may lead to permanent hearing loss.
These products are guaranteed against defects in components and workmanship only, for a period of two years from the date of shipment to the end user for countries of the European Union. For other countries, please refer to the law in effect. During the warranty period Focal will, at their discretion, either repair or replace products which prove to be defective, provided that the product is returned, shipping prepaid, to an authorised Focal service facility. Defects caused by unauthorised modifications, accident, negligence or any misuse are not covered by this warranty.

ALPHA 50
The ALPHA 50 is an active 2-way near field professional monitoring loudspeaker (2 internal amplifiers), composed of a 5" (13cm) woofer/ midrange speaker with a Polyglass cone loaded in a large laminar port and of an aluminum inverted dome tweeter.
ALPHA 65
The ALPHA 65 is an active 2-way near field professional monitoring loudspeaker (2 internal amplifiers), composed of a 6.5" (16.5cm) woofer/ midrange speaker with a Polyglass cone loaded in a large laminar port and of an aluminum inverted dome tweeter.
ALPHA 80
The ALPHA 80 is an active 2-way near field professional monitoring loudspeaker (2 internal amplifiers), composed of a 8" (21cm) woofer/ midrange speaker with a Polyglass cone loaded in a large laminar port and of an aluminum inverted dome tweeter.
Mains voltage
Your products must be earthed using the power cord supplied.
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.
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.
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.
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.
Once the position is defined, decouple the monitors from the stand / desk by positioning the 4 rubber pads provided. The gap and the right/left positioning of each loudspeaker permit to control the width, the centering and the global coherence of the soundstage (left/center/right), at the source of your recording/mixing precision.
We highly recommend you to position the monitors to have an equilateral triangle. The 3 points of the triangle are composed of the 2 monitors and your listening position.
In case of 5.1 set up, we recommend you to position the monitors on a circle to have the same distance between the sweet spot (listening position) and every single monitor. The center monitor should be placed at 0°, front right monitor at 30°, rear right monitor at 110°, rear left monitor at 250° and front left monitor at 330°.
As in all brand new loudspeaker, the drivers need some run-in period: the ALPHA transducers are mechanical elements demanding a little time to settle and adapt to the climatic environment. This period will vary, depending on the working conditions and may take up to a few weeks. Avoid pushing the speakers very hard during their first hours of use, but to accelerate the run-in process, it is good practice to operate the speakers at moderate levels for 20 hours or so, with programs having significant low frequency content. Only once the transducers have come to stabilize will you get the optimum performance.
