US BLASTER USB 7004
Our USB 7004 has 3 channels (A, B and C) of which each includes a fader and 1 channel
without any fader. This last channel enables a microphone to be used; the microphone
volume level can be set using the gain control. You will surely appreciate the long,
flexibly operating (100 mm) ALPS faders, which are mounted so that any dirt is
prevented from entering them and, therefore, a long-term trouble-free operation is
ensured. The 3 channels have 2 inputs to connect, besides turntables, line signals. Due
to the button situated next the channel input control, switching from Input 1 to Input 2
is easy because switching the plugs is eliminated.
Extra attention is paid to tone adjustment: perfect trebles including their boosting,
middle tone presence and beautiful basses. In addition, 3 killers enable bass, middle
tone and/or treble to be removed from X-fader within a second. The X- fader operates
on 2 external faders and Transform switches add music fragments from one channel to
those from the other.
Pre-listening operates on both channels and uses an outstanding amplifier, which is
equipped with a switch to reproduce pre-listening and master signal at the same time.
The balanced master output is fitted with chassis XLR connectors and the built-in relay
prevents undesirable cracking noise (plops) from occurring so that your sound system is
protected in an optimum manner.
In addition to the master output, the USB 7004 includes a Sub output, Monitor output
and 2nd Phones output.
