From the rear input panel is possible to configure the speakers in order to have the perfect response
from the ambience in which are located.
Input Sensitivity Control
The input sensitivity can be adjusted through this control from -6 dBu to +6 dBu. By turning it
clockwise the input sensitivity is increased. The central (0 dBu) and the 2 extreme positions of
the control (+6 dBu, -6 dBu), are dented.
Dip-Switch Settings
Bass Tilt (A, B dip-switches)
This setting is a low-shelf shaping filter that reduces frequencies below 500 Hz by the selected
amount (OFF, -1dB, -2dB, -4dB). This filter helps to correct the progressive increase of mid-low and
low frequencies due to resonances in small rooms.
The amount of correction will depend on the size and shape of the room (a bigger correction for
smaller and regular shaped rooms). A large room shall require no correction.
Bass Roll-Off (C,D dip-switches)
This filter that reduces the very low frequencies. If the switch is set in OFF position the filtering is
bypassed.
In the - 3 dB or - 6 dB position the low-shelf filter reduces frequencies below 80 Hz by the selected
amount. The low frequency attenuation is necessary when loudspeakers are placed near the room walls or corners.
The amount will depend on the specific situation (in general -3 dB for wall placement and -6dB in case of corner placement).
The 80 Hz High Pass filter apply to the input a Butterworth high-pass filter with cut-off frequency
at 80 Hz. This filter will be used for vocal monitoring purposes or when the Mytho monitors are used in
combination with a subwoofer.
Woofer (E dip-switch)
It turns on/off the low frequency amplifier. This switch must be kept on and set to MUTE for testing purpose only.
Power Led (F dip-switch)
This switch in low position turns off the LEDs around the RCF logo in front of the speaker. This option can be
required when the positioning of the Mytho Monitor is close to video sources or in residential applications.
Tweeter (H dip-switch)
This switch in low position mute the high frequency amplifier. This option will help evaluating the proper
working condition of the bass channel. This switch must be kept on and set to MUTE for testing purposes only.
Treble Tile (I, J dip-switch)
This setting is a high-shelf shaping filter that increase or reduce frequencies above 6 kHz by a selected amount.
A room can be very dull or very bright depending on wall materials. This filter help to correct the behaviour
in the high frequencies for a specific room. For a normal room no correction shall be applied (0 dB position).
For a dull room the treble tilt filter shall be set at +1 dB. The filter shall be set at -1 dB or -2 dB for a
bright or very bright room.
Equalisation (K dip-switch)
The woofer emission is omni directional for very low and mid-low frequencies but tend to be more directive
for mid frequencies. When the room is small the amount of reflections from the walls is bigger for the very
low and mid-low frequencies that will tend to be to be predominant compared to mid frequencies in case of same
axial emission.
When this switch is set to LINEAR POWER response a dedicated filter compensates this lack of mid frequencies
from the woofer channel. In medium to large rooms, where the wall reflections tend to be negligible, this
switch must be set in the LINEAR FREQUENCY response.
Desktop Control (L dip-switch)
This control reduces the emission in the frequency range (centred in the 150 Hz octave) that is usually
boosted when studio monitors are directly placed on a reflective surface (e.g. the mixing desk, a table, etc.).
If Mytho Monitors are placed in this positions set this switch ON to obtain a linear listening.
