effect. Turning the control to the right increases the reverb decay time.

  CHORUS (with Reverb)

: When the control is in the last 1/3 of rotation it selects 

the CHORUS effect, with optional Reverb. The first setting will be a slow chorus 

swell without Reverb. Turning the control to the right will increase the Chorus 

speed. REVERB is added at the half-way mark and the Chorus speed settings are 

repeated from slow to fast.

15.  LINE OUT XLR JACK

  The LINE OUT XLR provides a balanced output for going direct to a house system, 

recording input or to other powered systems like a powered subwoofer. The LINE 

OUT signal is affected by the channel LEVEL, EQ controls and internal DSP effects.

  With the LINK TO MAIN switch OUT, the XLR output is adjusted from the LINE 

OUT LEVEL control, and the signal is not affected by the MAIN level. 

  With the LINK TO MAIN switch IN the XLR output is adjusted by the MAIN control. 

  The XLR is protected against Phantom power (DC voltage) on cables coming 

from phantom powered mixer inputs. Ground pin 1 of the XLR is lifted to 100 

Ohms above the chassis ground to prevent hum from grounding issues.

16.  LINK TO MAIN SWITCH

 (LINE OUT XLR)

  If the LINK TO MAIN switch is set to the OUT position, the LINE OUT XLR output 

level is adjusted from the LINE OUT LEVEL control and the signal is not affected 

by the MAIN level. 

  With the LINK TO MAIN switch IN, the LINE OUT XLR level is adjusted from 

the MAIN volume control along with the S600B speaker outputs. This provides 

better control when connecting a powered subwoofer to the S600B; once a good 

bass balance is acheived, the MAIN volume will also control the subwoofer level.

17. PHONES JACK

  The PHONES jack is a stereo 1/4” jack designed for connecting headphones, tuner 

or stereo recording device. The volume is adjusted by the DIRECT OUT LEVEL 

control, containing the audio mix from the channel LEVEL settings. To listen to 

headphones without hearing the other speakers, turn down the MAIN control and 

adjust the headphone volume with the DIRECT OUT LEVEL control.

18. LINE OUT LEVEL (PHONES)

 The DIRECT OUT LEVEL controls the output level to the 1/4” PHONES jack and 

with the LINK TO MAIN switch OUT, also controls the XLR output. 

  With the LINK TO MAIN switch IN, the XLR output is only adjusted by the MAIN 

control.

19. SPEAKER OUTPUTS

  The S600B has two 1/4” SPEAKER OUTPUTS connectors, each connected to 

a different amplifier allowing stereo operation when the R (Right) jack is used.

 For the best perfomance use the matching S648 extension speaker featuring 

identical drivers and cabinet design as the S600B.

  The L (Left) speaker jack is connected in parallel with the internal S600B speaker 

system amplifier. You may connect one S648 extension speaker or a speaker with 

an impedance of 8 Ohms or higher. 

  The R (Right) speaker jack is connected to a second amplifier and activates 

stereo mode when plugged into. Stereo sources from CH.5 or CH.6, including 

the 

Bluetooth®

 audio connection, will then be heard in stereo. 

You can connect up to two S648 extension speakers to the R (right) speaker jack, 

or speakers with a total impedance of 4 Ohms or higher.

If you go below the minimum speaker load rating, the S600B will protect and 

shut off. 

20.  POWER SWITCH / LED

 The POWER switch turns the amp ON or OFF. The green POWER LED will light 

approximately 3 seconds after the POWER switch is turned on.

  To charge the S600B from AC power, the POWER switch must be ON.

21. AC POWER JACK & FUSE

  The AC POWER JACK will accept 90VAC to 250VAC, 50Hz or 60Hz. Plug the 

cord into a grounded 3 prong power source. No attempt should ever be made to 

use the AC cord without the ground connected. 

  A locking AC cord (Carvin part# 120V18L7) is supplied. However, a standard AC 

cord can be used. (for European 230V use a CEE-7 plug cord set).

 To detach the cord from the amp, press the release lever on the underside of 

the cord near the amp.

  The FUSE for AC power is located internally near the AC input. To check or 

replace, first turn the POWER switch 

OFF

 and 

remove the power cord

. Remove 

the 12 screws from the edge of the control panel. Carefully remove the control 

panel from the speaker enclosure.

The AC fuse type is a 5mm x 20mm 250V Slow Blow rated at 5A.

22. CHARGE 12VDC CONNECTOR, LED INDICATOR & FUSE

  The CHARGE connector is for charging the S600B internal battery from a car 

or other vehicle using an adapter such as our C12VDC power cord to plug into 

a 12V car accessory socket (cigarette lighter). The S600B will charge through 

the CHARGE connector whether the POWER switch is OFF or ON. The S600B 

can be used while connected to the CHARGE 12VDC connector for continuous 

use. It is recommended to start with a full charge.

  The LED will indicate GREEN when the battery is at full charge, OFF when it is 

slightly drained (OK), and RED when the battery is LOW.

NOTE: Charging a completely dead battery, running at high volume and multiple 

speakers each require more power and can drain your vehicle’s battery faster.

  The FUSE for the 12VDC power system is located internally near the 12VDC 

connector. To check or replace, first turn the POWER switch OFF, and remove the 

power cord. Remove the 12 screws from the edge of the control panel. Carefully 

remove the control panel from the speaker enclosure.

The battery fuse type is a 6.35mm x 32mm 250V Slow Blow rated at 15A.

23. ACCESSORY BAY 

(FOR OPTIONAL UHF WIRELESS RECEIVER)

 The S600B is designed with an accessory bay which allows direct mounting of 

our UX600R UHF Wireless Mic/Instrument receiver, for use with the UX600M 

wireless handheld microphone or the UX600B beltpack transmitter. The 

UX600R plugs directly into the bay without any connectors to connect.

  Audio from the UHF receiver will be heard through Channel 4 while allowing 

full use of the CH.4 XLR input.

  To mount the receiver in the accessory bay, first remove the adhesive cavity 

cover. Remove the bag containing 4 mounting screws. Slide the unit into the 

bay until you feel some resistance, then press more firmly as the receiver is 

seated and the face panel meets the S600B. Screw in the 4 screws, being care-

ful not to strip the plastic housing.

HELPFUL HINTS:

NO SOUND

:  

- The channel LEVEL or MAIN volume are set to “0”.

- Speaker Output jack has been shorted or not fully plugged in, triggering protection circuits.

POOR HIGH FREQUENCIES

:

- The HI frequency EQ control is set too low.

- Set the Hi-Z impedance switch IN for instruments on Ch.1 or Ch.2.

AMP SEEMS VERY SENSITIVE TO INPUT SIGNALS

- Adjust the channel LEVEL or MAIN volume.

- Turn OFF the GAIN switch for Ch.1-4.

FEEDEBACK FROM MIC OR INSTRUMENT

- Keep the mic or the face of the instrument pointed away from the speakers.

- Use the EQ controls to reduce feedback or reduce the channel LEVEL.

DEVICE DOES NOT CHARGE WHEN CONNECTED TO USB CHARGE PORT

:

- The phone or device battery is too low and is pulling too much power from the charge port, 

which will stop the charging.

FOR MAXIMUM OUTPUT

:

- Connecting an extension speaker to the “R” Speaker Out will make use of the second 

internal amplifier. The S600B will drive a total of 3 extension speakers. Every time you 

double your speakers your acoustic output goes up by a factor of four.

BATTERY OPERATION AND CHARGING

  

The 

S600B

 features a rechargeable 12 volt battery system which is able to power 

the unit without connecting to a wall AC socket.

  

MAXIMIZING BATTERY LIFE:

 Run time will vary depending on speaker volume and 

the number of speakers connected. The S600B alone can run for over 2 hours at 

100W peak power. At lesser volumes the S600B can run with all extension speakers 

for 4 hours or more. If the CHARGE LED near the power switch blinks RED or if 

the sound becomes distorted, lower the volume for better sound and longer play.

  

CHARGING:

 The battery will charge when the unit is powered ON from AC power, 

or it can be charged through the CHARGE 12VDC connector. Charge time for a nearly 

dead battery to full charge is approximately 6 hours.

  

BATTERY REPLACEMENT:

 If battery run time is greatly reduced after many charge 

cycles it may need replacement (Carvin part #

B600

).

 

To replace the battery first turn 

the POWER switch 

OFF

, and 

remove the power cord

. Remove the 12 screws from the 

edge of the control panel. Remove the panel from the speaker enclosure. Disconnect 

the wires from the battery posts (leave these wires connected to the circuit board 

to prevent shorting the battery) and disconnect the 4-pin speaker connector from 

the circuit board. Remove the nut and wood block holding the battery. Secure the 

new battery with block and nut. Connect the wires with the correct 

+/-

 polarity.

Replace the control panel screws by hand to avoid stripping (after repeated use).
