The System 9098 DMA contains two high quality signal paths that can be used as
a stereo pair or two individual paths. When used with a stereo mic setup, the
central WIDTH and M-S controls enhance the manipulation of the stereo image.
The DI (Direct Injection) switch changes input from the rear XLR to the front panel
jack socket. In DI mode, the input impedance is greater than 100kOhms for use
with guitars and synthesisers.
A phantom power switch is fitted for use with capacitor mics
and applies phantom power to the rear mic input XLR.
A phase invert button is fitted to easily correct any phase anomalies
caused by difficult mic placement or mis-wired cables
The high pass filter attenuates signals below 120Hz@18dB/Octave.
The DMA is capable of output levels in excess of 25dBu. The switched gain control
provides a range of 0-66dB in 6dB steps, so when using the minimum gain setting of
0dB only the most extreme sources produce an overload.
The variable Trim control has a range of /- 6dB allowing fine
gain adjustment between the 6dB switched gain steps. It also
allows the gain to be extended by 6dB at either end giving an
overall gain range of -6dB to 72dB
