MAS Flex Series Use and maintenance manual

MAS-210 Flex controls
As illustrated in the picture at the left there are
spaces for four switches.
Top: The tweeter control switch. This switch
will allow selection of one, two, or no tweeters.
The default setting is (marked with an *) the
single tweeter setting.
Bottom: The Voicing control Switch. This
controls the signal phase between the Mid/High
section and the Woofer section. The default
setting (marked with an *) is in phase.
Arming Switch SW1: This switch arms or
disarms the DARK setting in SW2. The default
setting (marked with an *) is Neutral or Off.
Bright/Dark SW2: This switch controls
Mid/High output in relation to the Woofer
section. The default setting (marked with an *)
is Dark. However, unless the Arming Switch
SW1 is lifted to the Arm SW2 setting SW2
remains in the Neutral setting and the Dark
setting is not enabled.
Placing all the switches in their Default settings
places the cabinet in a Neutral voicing with an
even response curve. In this setting the cabinet
is +/- 7db from 35Hz to 16Khz.
Switching in operation:
The MAS-210 flex is shipped with all switches in the Default or Neutral setting.
This is a good place to start when finding desired tone. The instrument signal chain can
be adjusted and optimized prior to moving the Loudspeaker from its Neutral setting.
The Arming Switch SW1 on the 210 Flex allows a third voicing in the
Bright/Dark SW2 switch. With the Arming Switch SW1 in the Default setting (Neutral)
the Bright/Dark switch is not allowed access to the internal PXB circuit thereby not
allowing the Dark voicing. In this mode the Bright/Dark SW2 switch will only change

voicing from Neutral to Bright. This allows rapid change from Neutral to Bright without
accidental engagement of the Dark setting. When the Arming SW1 switch is lifted to the
Arm (Arm SW2) position the Bright/Dark SW2 switch then has access to the PXB circuit.
If the Bright/Dark SW2switch is in the Bright position the PXB circuit remains
disengaged. If the Bright/Dark SW2 switch is then put into the Dark position the PXB
circuit is engaged and the cabinet enters the Dark voicing. The PXB circuit causes a
slight decrease is sensitivity of the Mid/High section and when pushed into high power
(700 watts or more) adds gentle compression and warmth. For a more aggressive tone
the Bright/Dark SW2 can be lifted to the Bright setting. This increases the sensitivity of
the Mid/High section. The Bright setting can be set no regard to the position on the
Arming SW1 switch.
The Tweeter switch can be used to set three different High Frequency options. In
the default setting one tweeter is operational. The switch can be moved to the Off (center)
position. In this position the High Frequency section is inactive allowing the Mid-range
drivers to produce High Frequency output extending beyond 8KHz. This will produce an
extended Mid-range presence with a High Frequency roll-off. The Tweeter switch can be
moved to the two tweeters (left) setting. This engages the second tweeter and makes a
subtle change in the High Frequency crossover. This setting adds extra presence in the
10KHz range as well as the entire High Frequency section.
The Voicing switch is a phase control between the Mid/High section and the
Woofer section. This controls the interaction of these two sections in the Upper Bass /
Lower Midrange region of the loudspeaker. This is useful in controlling the bass contour.
In the Default setting this bass region is full and even. In the Non-Default setting this
bass region is thinned. This thinner contour allows greater bass control in boomy
environments or to create a cleaner sound when in Dark mode.
