GETTING STARTED QUICKLY
If you are like most players, you probably want to plug in your new amp and get started 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 FS22 foot switch, plug it into the rear foot switch jack
for switching the channels and effects. Note: The CH SELECT
SWITCH
must be in the OUT
position (CH 1) for the FS22 to function (only CH 2 will function if it’s in the wrong position).
Now, turn the POWER SWITCH ON. Gradually raise the volume and overdrive controls.
Check the BLUES SWITCH setting before adjusting the tone controls.
FRONT PANEL
1. INPUT 1 (INPUT 1/2 ON SX200C & SX200H)
Connect a 1/4” guitar cable to this input. The 1/2 CH SELECT SWITCH will toggle
between channel 1 and 2. Use a professional quality 1/4” plug shielded guitar cord
(Carvin SH25) no longer than 25 feet. A long cable will reduce the overall treble response
from your pickups. Note: For remote footswitching leave the 1/2 CH SELECT SWITCH
in the “out” (CH 1) position when connecting the FS22 footswitch.
2. INPUT 2 (DUAL CHANNELS SX200C & SX200H ONLY)
To use the true dual channel feature of the SX200 and SX200H, plug a second guitar into
INPUT 2. When a guitar is plugged into both inputs, the channels become independent
of each other and can be played simultaneously.
3. CHANNEL SELECT
Set the channel switch to the desired channel. The LED’s next to the CHANNEL 1/2 will
let you see which channel is functioning. Use CH 1 for overdrive/lead. Use CH 2 for clean
playing. For the FS22 footswitch to function, set the CH SELECT to the “ OUT” or “CH 1”
position.
CHANNEL 1 DRIVE
4. CHANNEL 1 INDICATOR
The RED LED will illuminate when the OVERDRIVE channel is selected.
5. CHANNEL 1 VOLUME
The volume of the drive channel is to be used as a master level control. For partial clean
output, set the VOLUME control to 10 and turn the DRIVE nearly off.
6. CHANNEL 1 DRIVE
The drive channel delivers 12AX7 tube saturation and EL34 power tube compression.
This channel incorporates a dual section lead DRIVE control with a 72 dB dynamic range
so you can get shimmering clean, a fabulous blues tone or 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 guitar away from the speakers.
7. BLUES SWITCH
The exclusive BLUES SWITCH adds the critical mid tones in the 525 Hz range that is 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.
8. CHANNEL 1 BASS, MID & TREBLE
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 with the different settings for your ultimate sound.
9. CHANNEL 1 PRESENCE (SX200C/H ONLY)
Channel 1 features its own PRESENCE for added treble. It’s frequency range is at the
very high end of the guitar spectrum (11k Hz) for shimmering, glassy harmonics. If your
sound is too bright with single coil pickups, you may want to adjust the PRESENCE con-
trol and TREBLE control.
CHANNEL 2 CLEAN
10. CHANNEL 2 CLEAN INDICATOR
The GREEN LED will illuminate when the CLEAN channel is selected.
11. CHANNEL 2 CLEAN VOLUME
Channel switching from the Drive channel into
CHANNEL 2
gives you crisps, 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.
12. CHANNEL 2 BASS, MID & TREBLE CONTROLS
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.
13. CHANNEL 2 CLEAN PRESENCE (SX200C/H ONLY)
For added clarity, the
CH 2 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 level of this control.
