Trickfish Amplification BULLHEAD MINI 500, Operation Manual

Connections:

�. 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.

�. With the amplifier in the "OFF POSITION" plug the male end of the AC cable into the wall 
outlet.

�. Connect the speaker using Neutrik Combo Connector on the rear panel - 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.

�. 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.

�. If you have a passive instrument plug it into the instrument input and select the “HI” setting on 
the attenuator switch.  If you have an active instrument then flip the attenuator switch to the 
“LO” gain setting.

Powering Up:

�. Turn the volume on your instrument to the loudest position.

�. Place the amp in the “mute” position.

�. 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 indicators).  When the top LED stays in the red your input is probably too hot and your 
signal will distort.  A little bit of the red LED on the peaks is OK.

�. Next, disengage the “mute” switch 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.

�. 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‐adjust the “Input 
Gain” once you’ve added EQ.
