Connections:
1.
Remove the AC cable from the package and firmly insert the female end in the AC receptacle located on the
back panel of your amp.
2.
With the amplifier in the "OFF POSITION" plug the male end of the AC cable into the wall outlet.
3.
Connect the speaker using Neutrik Combi-Connectors on the rear panel (they will accommodate either Speakon
or ¼” phone plugs)
. *
Make sure that you are using an "unshielded" speaker cable and that the polarity of the
cable is correct. Do not use a shielded instrument cable to connect speakers to an amplifier. Ensure that the cable
is good quality and that there are no nicks or abrasions of the insulation that could expose people or equipment
to the electrical potential that is present on the speaker conductors. Never allow speaker connections to short or
contact other metal objects. Do not connect output to anything other than a proper speaker load. Do not use a
shielded instrument cable to connect speakers to an amplifier.
4.
Now you can connect your instrument to the amplifier. Make certain that you are using a "shielded"
instrument cable to connect your instrument to your amplifier. If you are unsure of the type of cables you
currently own, we advise you take a trip to your local music store and purchase the appropriate cables.
5.
If you have a passive instrument plug it into
the instrument input and select the “HI” setting on the attenuator
switch (no blue light). If you have an active instrument then depress the attenuator switch until you see the
blue light come on, indicating “LO” gain.
Powering Up:
1.
When the Bullhead 1K is powered up by switching the AC Mains on the right hand side of the head, it will go
through a power-
up sequence. The lights will blink and you’ll see one of the red LED’s in the “Input Level
Indicator” flash. The amplifier is giving itself a test to ma
ke certain everything is functioning correctly. If the
amp is functioning properly the
all of the blue LED’s will be on.
2.
The Bullhead 1k always comes up in mute to protect your speaker system and your friendly audio engineer. Be
certain all is as you expect before you press the mute button
–
this helps to prevent your speakers from being
abused
–
and your friendly sound engineer will love you for it.
3.
Turn the volume on your instrument to the loudest position.
4.
Next, set the EQ controls (
bass, mid, and treble)
to zero
(twelve o’clock position)
and begin playing aggressively
while turning up the
Gain
control of the appropriate channel
(as indicated by the LED bar graph).
When the
LED meter lights are
green to yellow
there is still potential to increase the Gain. When the graph gets into the
red
your input is probably too hot and your signal will distort.
5.
Next,
disengage the “MUTE” button and slowly
turn the Master Control clockwise to the desired listening
volume. At this point you should be hearing your instrument amplified through the system.
6.
As you ADD EQ you are also adding gain and so, once you’ve turned up the Master and start to EQ, be aware
that the signal will INCREASE as EQ is added. You may have to re-ad
just the “Input Gain” once you’ve added
EQ.
