9—Working with Input Signals
This chapter describes how to get signals into the VS-2400CD’s analog and digital input
jacks and connectors. We’ll discuss setting analog input levels and configuring the
VS-2400CD’s coaxial and optical digital inputs. Finally, we’ll describe how to get your
input signals to the desired input channels.
Analog Input Signals
Making Analog Connections
When connecting an instrument, mic or other sound-producing device to the
VS-2400CD, connect one end of the device’s cable into the device, and the plug on its
other end into the appropriate VS-2400CD jack.
The VS-2400CD’s SENS knobs allow it to accommodate a wide range of input levels,
from mic level (-50 dBu) to line level +14 dBu).
About XLR/TRS Connectors
This instrument is equipped with balanced (XLR/TRS) type input
jacks. Wiring diagrams for these jacks are shown in this
illustration. Make connections after first checking the wiring
diagrams of other equipment you intend to connect.
Avoiding Feedback
If you’re listening to the VS-2400CD through speakers, and you’re using microphones,
feedback—unpleasant high-pitched squealing—can occur. To avoid feedback:
• make sure that your mics are pointed away from the speakers to avoid feedback.
• try to move the mics and speakers further apart.
• turn down the speakers’ volume.
Before connecting instruments, microphones or other external sound sources to the
VS-2400CD’s analog input jacks, bring the MASTER fader all the way down to prevent
damage to your speakers, headphones or other equipment as you make the connection.
After the connection’s been made, bring the MASTER fader back to its 0 marking.
If you’re using an AKG C3000B, Roland DR-20, Shure SM-57 or SM-10, or Lavaliere
mic, consider using the VS-2400CD’s Microphone Modeling to simulate the sound of an
expensive studio mic—see Page 220.
If a cable’s plug doesn’t exactly fit the input jack,
don’t force it
. Make sure you’ve
selected the correct VS-2400CD jack. If the jack seems too small or large, it’s most likely
the wrong jack. See Chapter 2 for detailed information on the VS-2400CD’s input jacks.
You may need to purchase an adaptor to use the cable with the VS-2400CD. If you’re
sure you’ve properly matched plug to jack and still have a problem with the connection,
consult the vendor from whom you purchased the plug or cable.
To prevent hazard or damage, ensure that only microphone cables and microphones
conforming to IEC-268-15A are connected.
Afin d’éviter tout risque ou dommage, ne brancher que des câbles de
microphone et des microphones conformes à la norme IEC-268-15A.
