Carvin sx300 ユーザーズマニュアル

If you are like most players, you probably want to plug in your new amp and get start-

ed playing right away.  You can read the rest of the manual later to learn the finer points
of operating your amp.  In order to get started you will need your SX AMP, a 120 or 230
AC grounded power outlet, your instrument, and a standard guitar cord.  With the amp
turned off, you may now plug it into the proper AC voltage.  

Now turn all the volume and overdrive controls off and set tone controls at their mid center

position.  If you have purchased the FS44 foot switch,  plug it into the rear foot switch jack
for switching the channels and effects.  Now, turn the POWER SWITCH ON.  Gradually raise
the volume and overdrive controls. Check the BLUES SWITCH and HI GAIN switch setting
before adjusting the tone controls.

Connect a 1/4” guitar cable to this input. Use a professional quality 1/4” plug shielded

guitar cord (Carvin SH25) no longer than 25 feet.   A longer cable will reduce the overall
treble response from your pickups.

Select the desired channel using front panel switches or FS44 foot switch at any time.

The LED’s  will let you see which channel is functioning.  Use CH1 for overdrive/lead, CH2
for lead/blues, and CH3 for clean playing.  

When channel 1 is selected, its RED LED will be illuminated.  When channel 2 is select-

ed its YELLOW LED indicator is illuminated.  Notice when the channel indicator is illumi-
nated, the Effects indicator (14) matches the selected channel's color.  This indicates the
stored effects setting when that channel is on. 

The volume of the drive channels are to be used as a master level controls.  For partial

clean output, set the VOLUME control to nearly 10 and turn the DRIVE nearly off. 

The channel drive delivers 12AX7 tube saturation and EL34 power tube compression.

This channel incorporates a dual section lead DRIVE control with 72 dB of dynamic range.
So you can go from shimmering clean to fabulous blues soft clipping to full blown over-
drive with total tube warmth.  For mild 12AX7 tube emulation, set the DRIVE control
between 2 & 3.  For some of the best saturation, set the control between 4 & 6.  For full
blown drive, set the control between 6 and 10 (your guitar volume should be turned all
the way up).  Because the SX AMP has a lot of  gain in the DRIVE control, you can get
guitar feedback.  If feedback is a problem, reduce the amount of DRIVE or move the gui-
tar away from the speakers.

The Hi-Gain switch adds extreme gain and super scooped mids.  This setting allows for
very long sustained notes and heavily over driven power chords.

The exclusive BLUES SWITCH adds the critical mid tones in the 525 Hz range that are so

important to great sounding blues-rock tone.  However, when the BLUES SWITCH is not
used (OUT), the SX delivers a great “scooped” sound for hard rock metal players.  It is
important that you pre-select this switch for your style of playing before adjusting the
tone controls.   

These active tone controls develop the heart of your sound.  It is important that you start

at the mid point (5) on each control.  The total range of these controls are a substantial 20
dB (±10 dB) with a center frequency at 80 Hz for BASS, 600 Hz for MIDS and 8k Hz for the
TREBLE.  These controls are very powerful in their effect, so take time to adjust each con-
trol for your ultimate sound.

The PRESENCE switch frequency range is at the very high end of the guitar spectrum (11k
Hz) for shimmering, glassy harmonics. If your sound is too dull, try the presence switch
for more highs.

When channel 3 is select its GREEN LED indicator is illuminated.

Channel switching from the Drive channels into CHANNEL 3 gives you instant crisp, clean

sounds.  Thanks to special mud-cutting circuits that work between the frequencies of 550
and 700 Hz, your guitar tones will be full and vibrant.

To start, set the BASS, MID & TREBLE controls at their center (5) position.  These con-

trols are most likely to be set according to the type of pickups used (dual or single coil).
Most musicians like to reduce the MIDs deeper bass and crisper highs.

For added clarity, the CH 3 PRESENCE control increases the highest guitar harmonics in the

8-11k Hz range.  A normal bright switch works only in the 3-5k Hz range leaving your sound
somewhat flat. Single or dual coil pickups will determine the use of this control.  

The 24-BIT processor provides a host of great sounding effects including FLANGE,

REVERB, ECHO, & CHORUS.  Turn up the LEVEL control to 5 as a starting position.  Turn the
LEVEL higher if more effect signal is desired.  Use the SELECT and the ADJUST controls to
get the desired effect. Move the effects ADJUST and SELECT controls to the desired effect
for each channel.  Each channel now has its own effects.  Smart Effects™ will automati-
cally store your last selected effect settings for each channel and will recall them when
you switch between channels.  As you select each channel, notice that the LED next to the
LEVEL control changes color to match the channel LED color to indicate that the effects
has been changed.  The settings are stored in memory even when the amp has been
