CONTROLS
INPUT
Electronically balanced input for the connection of high-level signal sources like mixing consoles or signal processors. Connections can be established using phone or alternatively XLR-type connectors.
Caution: Preventing the occurrence of spurious noise. Prior to connecting/disconnecting the input, set the level control to its counterclockwise stop.
OUTPUT
This connector is connected in parallel to the input allowing the through connection of the input audio signal.
LEVEL
dB-scaled level control for adjusting the power amp’s overall amplification. To prevent distortion and clipping of pre-linked mixing consoles, the control should generally be set to a value between 0dB and +6dB.
MODE
This switch allows selecting the operation mode of the M15. The cabinet’s internal active frequency crossover is automatically deactivated when set to FULLRANGE. The loudspeaker system transmits the entire frequency range. Setting the switch to the position MID-HIGH activates an active frequency crossover with 124Hz crossover frequency, so that only the audio signal’s mid-high range is transmitted. When using a M15 in combination with a M18 subwoofer, selecting MID-HIGH is generally recommended, to ensure linear frequency response of the M15/M18 combination.
Using the cabinet in MID-High mode in monitoring applications may be favorable for attenuating the reproduction of low frequency signals.
