Description

• SX Series Classic Tube Emulation, awesome digital effects, rich black vinyl covering, and the brass red jewel light continue to make the American-made SX Series one of the hottest amps on the market today!

• Emulation or Modeling? Unlike other “modeling” amps, the SX doesn’t just copy the sounds of other amplifiers – it actually emulates 12AX7 tube circuitry. The SX waveforms successfully “emulate” real tube waveforms that breathe and express warmth from a mild soft-clip to a full power-soaked sustain. Pro players and industry gurus have stated that the SX Tube Emulator actually sounds better than many tube amps!

• Two channels – Clean and Distortion. Each channel has its own independent volume control for setting up equal levels quickly and easily. The SX200 and SX200H add true “Dual Channel 1 & 2” capabilities allowing both channels to be played at the same time.

• Active Tone Controls All models feature Bass, Mid, and Treble controls on both channels. The SX200 and SX200H go even further by adding a Presence control to each channel for more high-end.

• 24-BIT EFFECTS Once you have your tone, add in just the right amount of lush reverbs, rich choruses, thick textured flagging, and pristine echoes using fully adjustable parameters for damping, decay, depth, speed, time, and regeneration–up to 256 24-Bit effects. The SX200 and SX200H add a second digital processor dedicated to creating a lush, concert hall reverb at the push of a button.

• SX MODELS The 50-watt SX50 with one heavy-duty 12” speaker is perfect for any venue. The SX100, SX200, and SX200H feature a full 100-watt RMS – plenty for most situations. All combos & stacks feature heavy-duty speakers that provide awesome guitar reproduction – from clean to blues to scream metal. The SX200 features two 12” speakers for an even bigger sound. The SX200H head can be paired with either a 4×12 half stack or 8×12 full stack.

• REAR PANEL CONNECTIONS All back panels feature a voiced LINE OUT for recording or running a slave amp, HEADPHONE jack, EXTENSION
  SPEAKER jack and a FOOT SWITCH jack for the optional FS22 (for remotely changing channels and turning on/off the effects). The extra dedicated reverb on the SX200 & SX200H is controlled by a front panel switch. The SX200 & SX200H also add SEND/RETURN jacks for your own external effects. A 4, 8, 16Ω impedance switch is featured for matching speakers.

• RUGGED CONSTRUCTION SMT surface mount electronics ensure consistent, reliable performance and are nearly impervious to bumps and vibrations. Strong, lightweight plywood cabinet (not particle board), aluminum chassis, steel grille, and corners deliver one of the lightest, yet most rugged amps available.

Front & Rear Panel Controls

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 to switch 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 SX200 & SX200H)
   Connect a 1/4” guitar cable to this input. The 1/2 CH SELECT SWITCH will toggle between channels 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 SX200 & 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 LEDs 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 overdrive 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 tones. 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 midpoint (5) on each control. The total range of these controls is a substantial 20 dB (±10 dB) with a center frequency at 80 Hz for BASS, 600 Hz for MIDS, and 8k Hz for TREBLE. These controls are very powerful in their effect so take time with the different settings for your ultimate sound.

9. CHANNEL 1 PRESENCE (SX200/H ONLY)
   Channel 1 features its own PRESENCE for added treble. Its 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 control 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 and 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 controls 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 (SX200/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.
    DSP EFFECTS SECTION

14. SMART EFFECTS™ ADJUST (PARAMETER) CONTROLS
    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. Each channel now has its own effects. Move the EFFECTS ADJUST and SELECT controls to the desired effect for each channel. Smart Effects™ will auto-matically 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 1 /2 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 turned off. To change the stored effect, simply select a new effect. Note: The SELECT and the ADJUST controls do not rotate to their stored settings. Make note of your favorite effect settings.

15. EFFECT PARAMETERS
    Each of the four effects has a variable parameter that can be easily adjusted. Each “SEL “PARAMETER” is described below.

    • ECHO: SELECT the amount of the regeneration (repeating). Now select the ADJUST control for the shortest or longest delay time between the original signal and the echo.
    • REVERB: SELECT the amount of presence (high frequencies) in the reverb. Now turn the ADJUST control to provide the minimum or maximum decay.
    • CHORUS: SELECT the amount of reverb with your chorus. Now turn the ADJUST control to increase the depth.
    • FLANGE: SELECT the amount of speed with your flange (phasing effect). Now turn the ADJUST control to increase the depth.

16. SX200 & SX200H ALTERNATE REVERB SYSTEM
    The SX200 & SX200H also feature an alternate reverb system that is independent of the Smart Effects™ system. By pushing in the REVERB SWITCH, you have a modest amount of reverb added to both channels to enhance your sound. The FS22 footswitch does not externally control this reverb, which allows you to have reverb on at all times whether Smart Effects™ is ON or OFF.

17. EFFECTS OUTPUT LEVEL CONTROL
    The effects LEVEL control is used to set the number of effects you want blended into your guitar. This control affects the overall effect levels including the alternate reverb system featured on the SX200. Note: The effects level is not controlled by the Smart Effects™ memory so you must manually change it if you need different levels between channels.

18. POWER ON/OFF SWITCH & PILOT LIGHT
    The front power switch will turn on the power to the amplifier. The brass jeweled red pilot light illuminates when the amp is powered on.
    REAR PANEL

19. FOOTSWITCH
    Carvin’s FS22 dual footswitch is recommended for remote channel switching and DSP effects ON/OFF switching. Most foot pedals with 2 switches featuring a stereo plug will work. For channel switching, be sure that the 1/2 CHANNEL select switch between the channels is in the “OUT” position. If only CH 2 works, the 1/2 channel select switch is in the wrong position.

20. HEADPHONE
    The stereo HEADPHONE 1/4” jack is “CABINET VOICED” to prevent excessive highs. This greatly reduces ear fatigue.

21. CABINET VOICED LINE OUT OUTPUT
    The voiced 1/4” LINE OUT gives the same response as if you were micing the speaker. Special equalization reduces the harsh highs that are normally associated with a line-out signal.

22. SPEAKER OUTPUT
    A 1/4” SPEAKER OUTPUT is featured to operate an extension speaker system. The minimum impedance of an extension speaker for the SX50, and SX100 is 8Ω. The SX200 and SX200H have a switchable impedance of 4, 8 and 16 ohms. Set this accordingly when adding additional speakers.
    IMPORTANT: TO ENSURE THAT THE SX200 DOES NOT SHUT OFF (PROTECTION MODE), PLEASE SELECT THE PROPER SPEAKER IMPEDANCE ON THE REAR. IF YOUR SX200/H TURNS OFF DURING A PERFORMANCE, SET THE IMPEDANCE TO 4Ω.
    Speaker/Switch Setting

      Note: these settings may not be suitable for cabinets with different speakers.
      Amp Model/Cabinet/Switch Setting

    • SX200 Combo 2×12 8Ω

    • SX200 2×12 ext. cabinet (total 4×12) 4Ω

    • SX200H 4×12 8Ω

    • SX200H 8×12 4Ω

23. EFFECTS LOOP (SEND & RETURN) (SX200/H ONLY)
    Although the SX200 has built-in effects, you may want to use its separate effects loop. For the lowest noise from a pedal effect, use this effects loop instead of plugging the guitar into the effects and then into the amp. To use the EFFECTS LOOP, plug the input of your effects into the SEND jack and the output of your effects into the RETURN jack. Use shielded cables.

24. AC POWER & FUSE
    The AC POWER CORD is designed to operate with any voltage from 90-250VAC, 50- 60Hz. Plug the cord into a grounded “3” prong” power source. No attempt should ever be made to defeat or use the amp without the ground connected. The internal FUSE is located inside the chassis. This is not user-serviceable. Contact Carvin’s Service Department at 800-854-2235 or carvin.com.

HELP SECTION

• AMP WILL NOT TURN ON
  Check the power to the amp. Check for tripped circuit breakers, unplugged extension cords, or power-strip switches that may be turned off.

• SX200/H AMP SHUTS OFF WHILE PLAYING
  Check the rear SPK IPM switch to make sure it is set properly. Switch to the 4Ω position if you are unsure where to set it. If the problem continues, contact our service technicians.

• NO OUTPUT with POWER light ON
  Make sure that your speaker is functioning and not blown. Check input, cables & effects connected to the effects loop, and extension speaker cables for defects & connections. a) Also verify the effects loop is working by inserting a 1/4” stereo plug into the return jack and short the tip and ring. If the amp works by doing this, the effects loop jack is defective.

• KEEP YOUR AMP LOOKING NEW
  Try to keep your amplifier free from dust and moisture. To clean, use a damp cloth to wipe the control chassis panel and wipe the vinyl covering. Use a dry cloth to be sure the moisture is removed.
