HEADPHONE JACK
The headphone feature allows the user to monitor their sound via the use of stereo headphones. "Silent"
practicing can be achieved by removing the speaker cable from the back of the Baby Blue electronics. Do not
remove the cable from the cabinet jack only as there is a chance the cable could hit a "ground" and
momentarily short out the power amp. NO HARM will be done to your amplifier by not having any speakers
plugged in.
WARNING: Stereo headphones must be used in this jack as mono headphones will short out one side.
Since the headphone "amp" is actually a reduced signal from the power amp, the Headphone volume is
controlled by the Master Volume.
EXTENSION SPEAKER
The Extension Speaker jack can be used to plug in a second set of speakers. If you use this feature, make
sure that the impedance of the cabinet that you are plugging in is NOT LESS THAN FOUR (4) OHMS. Use a
good quality speaker cable that is at least 18 gauge or heavier (the lower the gauge, the heavier the wire).
DO NOT USE INSTRUMENT CABLE FOR HOOKING UP SPEAKERS!!
SPEAKER FUSE
This feature is provided to protect your speakers in the unlikely event of a power amp failure or your power
amp from bad speakers or their respective cables. This fuse can open (blow) if your amp is on and you are
playing while plugging in the internal speakers or an extension speaker cabinet. This is because the power
amp is momentarily shorted out to ground. Always check this fuse first if no sound is coming from your
cabinet(s). Correct size and rating of the speaker fuse is: 3AG, 6 amp, fast blow.
SPEAKER JACK
Use the Speaker jack to plug in the internal speaker system found in your Baby Blue.
A/C LINE FUSE
The line fuse can open (blow) due to power surges or high powerline transients. This fuse will also open in the
event of an electronics failure inside your amplifier.
Correct size and rating of the Line (Mains) fuse is 3AG, 3 amp slo blo for 120V operation and 1 1/2 amp slo
blo for 240V operation.
DO NOT DEFEAT THE PURPOSE OF THIS FEATURE BY USING A FUSE WITH A HIGHER RATING. IT CAN
FURTHER DAMAGE YOUR AMP AND VOID YOUR WARRANTY.
