SWR Baby Baby Blue Operating Instructions Manual page 18

Note: Inserting a plug into the Effects Receive jack activates the Effects Blend control. The control
receives this command through the ground created by the phone plug making contact with the jack.
The plug must be a mono plug (tip and ground). If you have a stereo plug only, it will be necessary to
tie the ring and the ground together.
HEADPHONES JACK (STEREO ONLY)
By inserting a set of stereo headphones into this jack you can monitor your sound more closely in a studio
situation, or practice silently (in conjunction with the Speaker On/Off Switch on the back panel) so as not
to completely annoy your neighbors. The headphone volume level is adjusted by the Master Volume. We
suggest you begin with the Master Volume full off (counter-clockwise), then slowly bring up the volume to
the desired level. If you hear some distortion in your headphones that isn't present through your speaker
system, turn down the Master Volume. You are probably overdriving your headphones and could ruin them,
to say nothing of what you may be doing to your ears.
Any impedance headphones will work. However, optimum impedance is 75 ohms.
SPEAKER FUSE
The speaker fuse is provided to protect your speakers in the unlikely event of a power amp failure or to
protect your power amplifier from incorrect speaker impedances or hookups. Size and rating of the fuse is
4 amp, fast-blo. Do not defeat the purpose of this feature by using a higher rated fuse as it can damage
your amplifier and void your warranty.
The fuse can open as a result of a fault in an extension speaker cable, the speakers themselves, or the
power amp being sent well into clipping. With this in mind, it is wise to carry extra fuses at all times.
LINE FUSE (A/C OR MAINS FUSE)
This fuse is provided to protect the internal electronics against power surges, etc. It also protects the unit
against itself should one of the internal components fail. If this fuse should open, replace it with the same
type of fuse and rating. Do not defeat the purpose of this feature by using a higher rated fuse as it can
void your warranty.
Proper rating of the fuse is as follows:
United States (120V): 3 amp slo-blo
Japan (100V): 3 amp slo-blo
Europe (230V-240V): 1.6 amp slo-blo
A/C CORD RECEPTACLE
This receptacle accepts a standard A/C power cable (supplied with the Baby Baby Blue in the United
States) used with almost all current musical, professional and household electronic devices. We
recommend great care when packing up. If it does become misplaced, a replacement cable can be
purchased at almost any music or computer store.
Note: The rating for this cable is 3 conductor, 10 amperes minimum. Look for this rating on the
cable. Make sure the cable is plugged in all the way in both the amp and the wall socket.
TWO-POSITION SPEAKER ON/OFF SWITCH
Located on the rear of the speaker cabinet section, this two-position switch can defeat the entire speaker
system if desired. Its primary function is to allow for silent practicing in conjunction with a set of stereo
headphones, but it can also be used as an overall mute switch. The upper position (marked "On") allows
the speaker system to operate in its normal capacity. The lower position (marked "Off") defeats both the
speaker and the tweeter in the Baby Baby Blue.
