Q&A - KAHAYAN Proaudio 8x4 MIDI Selector Operator's Manual

Q&A
Listed below are the most typical questions that we have received from the
users of the 8x4 Selector:
- Does the selector have an input buffer?
No, this unit is a transparent amp/speaker selector, with no active electronics
components in the signal path, just a very short high quality cable in the
instrument input.
- What impedance 8x4 selector uses? Can the 8x4 selector adjust the
amp impedance?
This is like a 'patchbay', you connect your amp with the speaker you want, we
don´t make adaptations. For example if you have an 8 ohm amp and you have
2 cabinets (16 and 8 ohm), you have to choose the 'correct' speaker.
- What guitar cable do you recommend? We don´t have a preferable brand
but the cables must have good quality and good soldering. We have
detected that a configuration with no quality cables changes the sound, then
users tends to think there is a problem in our 8x4 selector. Then, changes the
cables and recovers the definition and sound quality.
-Can I put all my amp heads in 'tower' configuration (One above the
other)? You can configure all your amp heads in the way you want but the
users must take attention of the position of the power transformer (connected
to the power grid) of the amps. Some amp brands put the power transformer in
the left side of the head, and others in the right side. If you combine this two
cases amp, probably the induction of this power transformer will affect to the
second amp and you could have some noise. We recommend put the same
head amps (transformer position) in one 'tower' and the others in a second
'tower'.
- If I turn off the 8x4 selector and amps are on, is there a problem? No,
because all the amps go directly to the internal phantom load in that case, and
all your amps will be loaded.
