Breaking-in
The transducers used in the Trio11 Be monitors are complex mechanical elements which require a breaking-
in period to operate at their best and to become acclimatised to the temperature and humidity of the
environment. The length of time this takes can vary depending on the conditions, and can sometimes last
several weeks. Avoid listening at high volume during the first few hours of use. In order to shorten the
breaking-in period, we advise you to let your equipment operate for about twenty hours at medium volume
with programmes having significant low-frequency content. Once the transducers' characteristics have
totally stabilised, you will be able to enjoy the full performance of your Focal products.
Settings and connections
1 - INPUT
The XLR connector enables you to connect a source with a balanced signal and has a standard wiring layout:
Pin 1 = ground (cable shield)
Pin 2 = in-phase signal (aka hot)
Pin 3 = reverse-phase signal (aka cold)

2 - INPUT SENSITIVITY

This selector allows you to adjust the input sensitivity of the monitor speaker according to the source (mixing
console, sound card...). If the source transmits an audio signal via an unbalanced line, set the input sensitivity
of the monitor speaker to -10 dBV. If the audio signal is transmitted via a balanced line, set the input sensitivity
of the monitor speaker to +4dBu.
3 - LF SHELVING
The LF SHELVING potentiometer allows you to activate or deactivate the volume correction below 250Hz.
We recommend setting the LF SHELVING potentiometer to +2dB when the acoustics of the listening room
naturally soften that frequency range. We recommend setting the LF SHELVING potentiometer to 0 when the
acoustics of the listening room are neutral. We recommend setting the LF SHELVING potentiometer to -2dB
when the monitors are placed near a wall or a corner.
4 - LMF EQ
This potentiometer allows you to adjust the level of the low-mid frequencies. The centre frequency is 160Hz
and the Q factor is 1. The corrections are made on a range of +/- 3dB. This correction is also useful if the
monitor speaker is installed on top of a mixing console. Activating this function will diminish the reflections
generated by the mixing console.
5 - HF SHELVING
The HF SHELVING potentiometer allows you to activate or deactivate the volume correction above 4.5kHz.
We recommend setting the HF SHELVING potentiometer to +2dB when the acoustics of the listening room
naturally soften this frequency range (mat environment). We recommended setting the LF SHELVING
potentiometer to 0 when the acoustics of the listening room are neutral. We recommend setting the LF
SHELVING potentiometer to -2dB or -3dB when the acoustics of the listening room naturally increase this
frequency range (clear environment).
