It also includes a two-channel mixer, that allows connecting to its inputs both MIC and
LINE level signals, due to the existence of an input level selector. Each input has a green led
“SIGNAL” indicator, showing signal presence.
The unit has an effective three-band tone control at the output of the mixer. An
electronically balanced “STACK OUT” output also allows connecting the Philos unit to other
self-amplified units or conventional amplifiers.
Concerning acoustic transducers, the unit uses a 12’’ woofer that can cope with large cone
displacements. A compression driver with a 44mm titanium diaphragm is used for the high
frequency way.
5. QUICK START
- Placement
Choose a placement with enough audience coverage, and with the minimum number of
obstacles between the speaker and the audience. The higher the unit is placed, the greater and
better audience coverage will be provided.
As it is a self-amplified unit, it requires a direct connection to a mains socket, as well as to
the sound sources that you want to connect. Please, consider all these circumstances.
- Mains connection
Read WARNINGS in point 2.
Make sure that the mains red switch is in “0” position.
Plug the mains cable’s connector in to MAINS input. Connect the plug to a grounded
mains socket.
- Audio connections
The Philos 12A unit allows the direct connection to two different sound sources by means
of two electronically balanced XLR3 sockets. These sockets can be set up for both LINE level
signals (high level signals such as: MP3 players, CD, keyboards, video, deck players...) with the
knob switched, and dynamic MICROPHONES (low level signals) with the knob non-switched. Make
sure that the selected position is the appropriated one.
When connecting the Philos unit to a stereo console, select the LINE position and connect
each channel to each one of the inputs.
Before connecting the Philos unit to other self-amplified units or amplifiers, make sure that
levels selected for the first unit are the correct ones for its stand-alone performance.
- Power up
Make sure that both volume controls are set in “MIN” position, and that tone controls are
set in central position.
Switch on firstly the sound source (MP3 players, CD, keyboards, video, deck players...).
Next, switch on the power switch (“I” position). It should light automatically, as well as the
“POWER ON” blue led, indicating that the amplifiers are correctly supplied.
As soon as there is signal at the inputs, even with the volume turned down, the green led
“SIGNAL” indicators should light. Next, turn slowly the corresponding volume control until reaching
the desired volume level, NO the maximum.
After that, select the desired equalisation and next check the available power margin,
making sure that the red “CLIP” indicator DOES NOT light. If this occurred, turn down the level,
because the internal amplifiers would be permanently overloaded and the sound would distort.
