8. STARTING UP
This is directly done via the POWER mains switch (10). Even is the power-up noise of
SAM412T is minimal, we highly recommend to power up all equipment in the following
order: sound sources, mixing units, equalizer, processors and finally power amplifiers.
The power down sequence is the inverse of the power up one.
9. EQUALIZATION
Tone controls (4, 5, 6) provide ±15 dB gain/attenuation for each of the three bands,
centered on 100Hz, 2kHz and 10kHz. Given this unit's application philosophy, tone
controls are designed to be set with a screwdriver, thereby preventing accidental
manipulation during normal usage.
10. VU-METER
The SAM412T has a VU-meter (9) to show the main mixing signal.
11. GROUND LOOPS, BACKGROUND NOISE
You should always make sure that the signal sources coming to the unit, as well as all
devices connected to its outputs, do not have their grounds interconnected, that is;
ground must never come from two different devices. Should this ever happen, noises
could occur and seriously interfere the sound quality.
Cable shields, when connected to the chassis, must never be linked together. This will
avoid ground loops.
The SAM412T mixer was designed to produce the lowest background noise.
Independently from the electronic design, the resulting background noise directly relies
on the correct use and installation of the mixing unit.
I. e.: setting a channel VOL to "2" and the output to "10" is not the same as the other way
round. In the first case, the signal coming to the mixing amplifier - which has got its own
noise - is low, and so is the signal-to-noise ratio (low signal). When the output amplifier
boosts the whole signal we will get a very high background noise. In the second case -
with the channel fader at maximum - the mixing level is high, and so is the signal-to-
noise ratio. When the signal reaches the VOL OUTPUT and is boosted, it will keep a
much better signal-to-noise ratio than in the preceding case.
