Sound Velocity; Ch1, Ch2, Ch1+2 Settings; Q/Bandwidth, Q/Gain And Shelving Slope Dual Mode Input - Martin Audio MA12K - 2010 User Manual

Analogue backup mode connection: the amplifier runs with AES3 input selected, in parallel mode. In the
above example diagram, the R channel of the AES3 stream is selected, which is the "Parallel from CH2"
choice from Source Selection submenu. Also the L channel can be used, by selecting "Parallel from CH1".
This signal goes, through processing, to both amplifier outputs. A cable with an analogue signal identical to
that provided by AES3 should be connected to IN1 of the amplifier for backup purposes. The level should be
accurately trimmed, by using the AES3 gain trim setting, or by changing the analogue signal level.
3.10.2.4

Sound velocity

This option sets the sound velocity used for time to distance conversions throughout the local interface. It
can be set from 320 m/s to 360 m/s.
3.10.3

CH1, CH2, CH1+2 Settings

The channel (or the channels) that are being edited are shown on the top-right corner in these sub-menus:
CH1, CH2, or 1+2 when you are editing both channels at once.
3.10.3.1 EQ
This menu lists the 16 parametric filters. You can move from filter to filter using the arrow keys.
The parameters are synthesised on the display. You can check all equaliser settings by switching through all
16 filters.
You can change the settings for the selected filter by clicking "edit".
You can enable the filter or set it to a flat response.
You can choose the filter type from the following types:

peaking (Peak)

low (LSh) and high (HSh) shelving (from 3 to 15 dB/oct)

low pass EQ (LPEQ) and high pass EQ (HPEQ)

bandstop (Notch)

bandpass (BandP)

allpass (AllP)
You can change:

The frequency in 1/96 octave steps from 20Hz to 20 kHz.

the gain – for peaking or shelving filters – in 0.1dB from –15 to +15 dB

the Q factor - for all filters except shelving – in 0.1 steps from 0.1 to 30

the shelving slope from 3 to 15 dB/oct
