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 two variable parameters that can be easily adjusted. The
SELECT
and
ADJUST
parameters are described below.
A) ECHO: SELECT
is the amount of the regeneration (repeating). The
ADJUST
controls the
delay time between the original signal and the echo.
B) REVERB: SELECT
is the amount of presence (high frequencies) in the reverb. The
ADJUST
is the decay time or length of reverb.
C) CHORUS: SELECT
is the level of background reverb with your chorus. The
ADJUST
con-
trol increases the depth.
D) FLANGE: SELECT
is the speed of your flange. The
ADJUST
control increases the depth.
16. SX300C & SX300H ALTERNATE REVERB SYSTEM
The
REVERB SWITCH
is an alternate reverb system that is independent from the
Smart
Effects™
system. By pushing in the
REVERB SWITCH
, a small amount of reverb is added
to enhance your sound. The
FS44
footswitch does not externally control this reverb,
which allows you to have reverb on at all times whether
Smart Effects™
are ON or OFF.
17. EFFECTS OUTPUT LEVEL CONTROL
The effects
LEVEL
control is used to set the amount of effects you want blended into your
guitar. This control affects the overall effect levels including the alternate reverb system.
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 (SX300C/H only)
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. INPUT B (SX300R only)
This input is the same as the front panel input. The front panel input when used will over
ride the back panel input. This back panel input is great in a rack mount situation where
other rack mounted gear is used in front of the
SX300R
such as wireless units, external
effects, and tuners.
20. FS44 FOOTSWITCH JACK
This jack is NOT a MIDI jack. It is design for the Carvin
FS44
quad footswitch. The
FS44
will give you remote control channel switching and Smart Effects muting.
21. HEADPHONE
The stereo
HEADPHONE
1/4” jack is “
CABINET VOICED
” to prevent excessive highs. This
greatly reduces ear fatigue. On the SX300R the +4/ -10dB switch affects headphone level.
22. 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.
IMPORTANT: TO INSURE THAT THE SX300C DOES NOT SHUT OFF (PROTECTION
MODE), PLEASE SELECTED THE PROPER SPEAKER IMPEDANCE ON THE REAR. IF
YOUR SX300C/H TURNS OFF DURING A PERFORMANCE, SET THE IMPEDANCE TO 4

23. SPEAKER OUTPUTS (SX300C/H only)
Both units have two 1/4" speaker output jacks and an impedance matching switch. The
SX300C
combo uses one of these jacks for the internal two
Celestion
speakers. Be sure to set this
switch to the correct impedance setting when plugging in external speakers on the
SX300C
.
24. EFFECTS LOOP (SEND & RETURN) (SX300C/H ONLY)
Although the
SX300C
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.
25. AC POWER & FUSE
The
SX300R
is design to operate from 90-250VAC (50 or 60 Hz). The
SX300C
combo
and
SX300H
head come in 120VAC and 230VAC models for best power amp perform-
ance. All models should be plugged into a grounded "3 prong" outlet. No attempt should
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

26. SX300R SPEAKER EMULATOR OUTPUT DIRECT
The speaker Emulator outputs are for D.I. (Direct) connections to a PA system. These
outputs are custom shaped using 4 stages of filtering to emulate a speaker cabinet that
has been mic'ed. Both unbalanced 1/4" and balanced XLR are provided for any situation.
The +4/-10dB switch provides a final output level adjustment. Use the +4dB setting for
line level and -10dB setting for instrument level.
27. SX300R MAIN OUTPUT SECTION
These jacks are for going to the main power amplifier that is running guitar specific
speakers. This output should NOT be used to go to a PA system or other system with
non-guitar specific speaker cabinets. Both unbalanced 1/4" and balanced XLR are pro-
vided for any situation. If you are using an amplifier (like the Carvin DCM series), it is
best to use the XLR connector for the best level and lowest noise to the amplifier. The
+4dB setting is for line level and the -10dB setting is for instrument level.
