Output & Solo Controls - Mesa/Boogie LoneStar Amplifier Owner's Manual

FRONT PANEL: Controls & Features
100W / 50W: Channel Power Select
TRACKING setting on the Rear Panel RECTIFIER SELECT switch.
Or, you might want the opposite and set Channel 1 to 50 watts of sparkling, yet forgiving clean performance and go for the bold auth-
ority of 100 watt power for Channel 2 set to a soaring high gain voice using the DRIVE circuitry.
Whatever scheme you choose to use, the ability to select the power rating of each channel adds incredible expression power to the
LONE STAR.
NOTE: The RECTIFIER SWITCH (Rear Panel) has a built in RECTIFIER TRACKING feature that ensures proper matching for each
power setting. In 50W, either a TUBE RECTIFIER or a silicon DIODE may be chosen as the rectification element with the Tube offering
the most give and elasticity. In the 100W setting, DIODE rectifiers are automatically brought on line and this is a proper match which
provides the reliable and powerful headroom of a 4x6L6 output section.
NOTE: At some point in your experimentation with the Channel Power Select switches, try setting one or both of the Channels to
50W and moving the Speaker Load to the 4 Ohm jack. This produces a brighter, snappier response that is great for certain applica-
tions, especially clean sounds.There is no right way, but the difference in response is definitely worth investigating for both clean and
overdriven sounds.

controls the volume of the power section.
NOTE: NOTE: NOTE: The Effects Loop RETURN jack can serve as a power amp input so that you may use the LONE STAR amplifier as a power
amp for either stereo reproduction or to incorporate additional pre-amps. Here are a few things to remember that will help you when
interfacing to the LONE STAR for use as a power amp only;
1.) Connect "Dummy" plug or loose cable to SEND jack. ( This prevents any possible loading that could result in diminished RETURN
sensitivity.)
2.) The OUTPUT Level will be the only active control on the Front Panel (the PRESENCE control of Channel 1 will be active only
when that channel is engaged - see #3 )
3.) The SOLO control may be used to footswitch to a pre-determined amount of boost when the footswitch is connected.
NOTE: Therefore, we recommend selecting Channel 1 when you wish to use the LONE STAR as a power amp.

OUTPUT: This control determines the overall output volume level of the amplifier. After the
controls, the OUTPUT control allows you to change the playing level by adjusting a single
control. The OUTPUT control is also wired as the Effects Loop Return Level control.

Should you ever use your LONE STAR amplifier as a power amp alone by inserting a signal
into the RETURN jack, the OUTPUT control will serve as the master level control.
NOTE: To use the LONE STAR amplifier as a power amp - use the EFFECTS RE- NOTE: NOTE:
TURN as an input. The SOLO control can be used to attain a footswitchable boost if the
Footswitch is connected. It is wired in parallel to the OUTPUT control and therefore also
