Congratulations on your purchase of the PA410 or PA620 mixer! These mixers are
the culmination of Carvin’s 50 years of knowledge and experience in the pro sound
arena. The quality and features included in these powerful little units make them rev-
olutionary and unheard of in their price range! Please take the time to review this
manual so that you may fully enjoy all the benefits your mixer has to offer.
PRO FEATURES
The PA series mixers give you pro XLR mic preamps, along with 1/4" line inputs on every
channel. Phantom power is provided on the XLR inputs for compatibility with high quality
condenser mics. Each channel also provides a MONITOR send, a GAIN switch for accom-
modating low and high input signals, EFFECTS send and LEVEL control.
ACTIVE EQ
Each channel of the PA series provides a HI and LOW shelving EQ with ±12dB of adjust-
ment range featuring an internally optimized midrange circuit, for easy, effective tone
adjustments that sound great for vocals.
BUILT-IN POWER AMPS
The amplifiers in the PA series mixers are powerful enough to easily drive your speakers
for excellent coverage and clean, punchy sound. The PA410 delivers 100 Watts RMS,
while the more powerful PA620 delivers 200 Watts RMS! (Note: Each model is designed
to be used with 8Ωspeakers (not 4 Ω). If the relay protection engages after 20 minutes
of heavy use (no output from the mixer while the power LED is on), you are using 4Ω
speakers. If the mixer goes into protect, let the mixer cool down and it will reset).
24-BIT DIGITAL PROCESSOR
Perhaps the most incredible feature of the PA series mixer is the "Full-Featured" 24-Bit Digital
Processor. You get awesome lush Reverbs, rich Chorus, crisp Delay and Echo, and thick,
layered Flanging – all with full band-width and pristine clarity. And with the PARAMETER
control, you can continuously modify each effect for up to 64 different sounds for a total of
256 effects! Nobody else has offered these features in a mixer in this price range!
MASTER SECTION
The master section of the PA series provides a MAIN volume for controlling your over-all
mix volume. A master MONITOR knob lets you control the over-all volume of an exter-
nal monitor amp. The TAPE IN control is for varying the level of the signal being received
at the RCA TAPE IN jacks. A PHANTOM POWER switch is provided for engaging or dis-
engaging power to condenser mics. Three controls EFFECT, SELECT, and PARAMETER,
are for setting up the full-featured Digital Effects. Finally, there is a master 7-Band
GRAPHIC EQ for fine tuning your over-all mix. It’s so easy to get a great sound!
CONNECTIVITY
The PA series mixers allow easy connections to most related equipment. There is a 1/4"
MAIN LINE OUT for sending the main signal to an external power amp or for plugging in
headphones. The MONITOR OUT is a 1/4" jack for feeding an external monitor amplifier.
RCA TAPE IN and OUT are provided for easy connection to keyboards, tape decks, CD
players, MiniDisc, computers, etc. The EFFECTS FOOT SW jack allows the connection of
the optional FS22 or equivalent footswitch for turning on or off your effects during per-
formances. Two 1/4" SPEAKER jacks provide quick, easy connection for two 8 Ohm
speakers.
CONSTRUCTION
Solid plywood construction, space-age aluminum chassis and a modern power supply all add
up to make the PA series the best-built and most lightweight, compact pro mixers available.
Technical advances like SMT (surface mount components) and incredible 24-Bit DSP ensure
that they are the best sounding and most reliable compact mixers as well.

LIVE SOUND SYSTEM
In a live sound reinforcement or a public address system (P.A.
System), the input signals to the mixer will come from the micro-
phones and instruments on the stage. Each microphone or instru-
ment to be amplified by the P.A. system must be connected to one
of the mixer’s inputs. If you have enough channels, try to mic each
stage instrument. This allows for the best overall sound control of
the instruments as they are mixed together and then amplified by
the P.A. system. This will also provide the ability to record your
performace with all instruments in the mix via the TAPE OUT RCA
jacks.
THE SOUND CHECK
The sound check takes some skill, but mostly patience from the
performers and especially you the system operator. If you get frus-
trated during the sound check the performers can lose confidence
and the sound may suffer due to things missed in the sound check.
The basic sound check follows this format: First test all micro-
phones and other input devices (direct boxes, etc.) before the per-
formers are included in the sound check. A good thing to also
check here is feedback in the monitors from the microphones.
Good positioning of the monitors and the use of the graphic equal-
izer solves most major monitor feedback problems. Now for a
sound check with the performers. First set the level of each per-
former individually and in cases where a performer has multiple
microphones, such as with a drummer, set each drum mic individ-
ually then the drum set as a whole. This is also a good time to
make some channel tone control adjustments to tailor the sound of
the individual performers and instruments. Next after setting each
individual, have the performers run through a song or a portion of
the show. Don’t hesitate to stop the performers if something needs
to be adjusted or if an individual performer or microphone needs to
be heard solo again. Remember the sound check is not a rehears-
al, but a system check, a time to work the bugs out of the system
so the show can go smoothly.

MIC CHANNEL FEATURES
1. XLR MICROPHONE INPUT
The XLR MIC input is designed for balanced low impedance
(microphone) input signals. The differential balanced input
amplifier reduces the common noise picked up on the
microphone cables. The XLR connector is wired as per the
industry standard, pin 1 is ground, pin 2 is non-inverting
(positive), and pin 3 is inverting (negative). Phantom power
is available on every XLR input jack when the phantom
power switch in the master section is pressed. This feature
allows condenser microphones to be run directly from the
mixer. Note: When using phantom power, make sure the
phantom power is switched off before connecting or dis-
connecting microphones to the mixer. It is recommended
to allow 5 seconds for the phantom power to discharge
before making any microphone connections. Also, to avoid
hearing a pop, turn down the master volume when turning
on the phantom power.
2. LINE INPUT JACK
The LINE input is a 1/4” phone jack designed for unbalanced
line and instrument level inputs. Examples to use in these
inputs are guitars, keyboards, mics, or a CD or tape player.
The line inputs can be used at the same time the XLR inputs.
3. +20DB GAIN SWITCH
The GAIN switch increases the input sensitivity on both the
LINE and MIC input jacks by 20dB. After determining the
input is too low for mixing with the level control, turn down
the level control, press in the gain switch and adjust the
level again. If distortion is heard regardless of the channel
LEVEL control’s setting, disengage this switch to eliminate
over-driving of the input stage.
4. CHANNEL LEVEL CONTROL
The LEVEL control adjusts the volume of the channel before
going to the MAIN master LEVEL. Here is where the indi-
vidual channel volumes are adjusted to make up the desired
mix heard at the main outputs. A general rule to prevent
interstage distortion is to always keep the MAIN master
LEVEL the same or higher than the channel LEVEL.
5. MONITOR LEVEL CONTROL
The MONITOR level control adjusts the volume of the chan-
nel going to the monitor mix. The monitor level control is
pre-channel level and pre-channel tone controls. This
means it is unaffected by adjustments in channel level and
tone controls. The purpose for this is so the main mix
adjustments for tone and level can be made without dis-
turbing the monitor mix.
6. CHANNEL EFFECTS LEVEL CONTROL
The EFFECT control adjusts the volume of the channel going
to the internal effects. Make sure the effects level is not set
too high, if the master effect PK (Peak) LED flashes red, turn
down the Channel Effect until it stops flashing. See # 11 for
more details.
7. CHANNEL TONE CONTROLS
Each channel features active tone controls LOW and HI. Both
function as boost (clockwise) & cut (counter-clockwise) con-
trols where the center 0position is neutral. Both LOW and HI
are shelving type tone controls with corner frequencies at
80Hz and 11.5k Hz respectively. It is suggested the channel
tone controls start out in their center 0positions. A good set-
ting for added dynamics is to set the LOW & HI at +6.
8. THE GRAPHIC EQUALIZER
The 7 band graphic EQ is an excellent tool to fine tune the
overall mix. Set all sliders to their center detent position.
When the sliders are in this position, they do not effect the
audio signal. When a slider is raised or lowered it boosts and
cuts the listed frequency respectively. One setting that can be
used to enhance your sound is to cut the mid range (set the
1KHz slider to -8) and raise the high and low frequencies as
shown. This is a common “smile” curve that gives a tight
punchy sound with
plenty of highs to
cut through a
crowd. The
Graphic EQ can
also help to reduce
feedback.
9. MAIN MASTER LEVEL CONTROL
The MAIN control is the master volume control for the mixer. The
MAIN will control the volume of the LINE OUT jack, the TAPE OUT
RCA jack and the internal power amplifier (speaker volume).
10. PHANTOM POWER
SWITCH AND LED
The PHANTOM power switch turns on the microphone
phantom power in the channel XLR jacks. This power is
used for supplying a bias voltage to condenser micro-
phones. The LED indicates the phantom power is turned
on. The phantom power will not damage dynamic micro-
phones.

QUICK START UP
If you’re like most new owners, you’re probably in a
hurry to plug your mixer in and use it. Here are some
brief instructions to get you going quickly. With the
mixer unplugged and the unit turned off, complete the
following procedures:
1. CONNECTING AC POWER TO YOUR MIXER
• Be sure to use the correct power cable for your country.
(120VAC or 240 VAC)
• Use only a grounded (3 prong) power outlet to prevent
a shock hazard and reduce hum and noise.
2. CONNECTING SPEAKERS
• Use the 1/4” SPEAKER jacks on the front panel to con-
nect up to two 8Ωspeakers. The speaker cables are to
be non-shielded with a minimum size of 16 gauge.
NOTE: Do not run your speakers through microphone
wire, guitar cables, or multi-conductor microphone
junction boxes or “snakes” as they are sometimes
referred to. This wire is normally shielded and of a very
light gauge causing a substantial loss of power.
3. CONNECTING INPUTS TO YOUR MIXER
• For low level balanced devices such as microphones, plug
into the balanced MIC inputs using a shielded XLR cable.
• For high level unbalanced devices such as instruments
& Keyboards plug into the LINE input jacks using a
shielded 1/4” phone cable. Set the GAIN switch so the
LEVEL control is not overly sensitive.
4. TURNING YOUR MIXER ON
• Turn all channel and master LEVEL controls to their off
positions
• Adjust all “EQ” tone controls— the channel’s HI and LOW
and the 7 Band Graphic EQ’s to their center position.
• Turn the mixer on by the rear panel POWER SWITCH and
watch for the POWER LED to light. Your mixer is now
ready to operate.

MASTER SECTION FEATURES

11. DSP EFFECTS SELECTOR
The 24bit processor will provide a host of awesome sound-
ing effects that include: Flange, Reverb, Echo, & Chorus. The
EFFECT control will adjust the volume level of the selected
effect. Remember each channel has its own EFFECT send
that will adjust the amount of signal sent to the effects
processor. The red PK LED will indicate when the effects sig-
nal from the channel is clipping. Lowering the channel
EFFECT control until the PK LED stops flashing is a good rule
of thumb when setting up your effects. (Note: An audible
note can be heard when adjusting the effects).
EFFECT PARAMETERS
Each of the four effects has a variable parameter that can be
easily adjusted.
ECHO: When the SELECT control is at the “7 O-clock” posi-
tion, it is selected to the first ECHO setting where you get a
single repeat echo (minimal regeneration). Turning the
PARAMETER control to 1 will provide the shortest delay time
between the original signal and the echo. Increasing the
PARAMETER
control to the
right will
increase the
time delay
between the
original signal
and the echo.
You can get a maximum of .5 second delay. To increase the
number of echoes, turn the SELECT control clockwise to “9
O-clock” (maximum regeneration).
REVERB: When the SELECT control is at the “10 O-clock”
position, it is selected to the first REVERB setting. Turning
the SELECT control clockwise will increase the amount of
high frequencies in the reverb. Turning the PARAMETER con-
trol to 1 will provide minimal decay time of the reverb.
Increasing the PARAMETER to the right will increase the
reverb decay time.
CHORUS: When the SELECT control is at the “1 O-clock”
position it is selected to the first CHORUS setting. Turning
the SELECT control clockwise will increase the amount
reverb in the chorus. Turning the PARAMETER control to 1
will provide a minimal chorus depth setting. Increasing the
PARAMETER to the right will increase the chorus depth.
FLANGE: When the SELECT control is at the “4 O-clock”
position it is selected to the first FLANGE setting. Turning the
SELECT control clockwise will increase the flanger’s speed.
Turning the PARAMETER control to 1 will provide minimal
flanging depth. Increasing the PARAMETER to the right will
increase the flanger’s depth.
12. MONITOR MASTER LEVEL CONTROL
The MONITOR master level control is the master volume
for the monitor mix which is sent to the monitor output.
This control receives its signals from the channel monitor
level controls.
13. TAPE IN
The TAPE IN control sets the level coming from the RCA
TAPE IN jacks. Just like the channel LEVEL control, the
TAPE IN will add this signal to your overall mix with your
MAIN control adjusting the entire mixer volume output.
14. MONITOR OUTPUT JACK
The MONITOR line out jack is the monitor mix from the
MONITOR master level control. This is a line level output to
drive an external power amplifier like our HT100M for sep-
arate floor monitors. This output will include any effects
mixed at the individual channels allowing you to hear your
effects in your monitors!
15. MAIN OUTPUT JACK
The MAIN line out jack is a line level post graphic EQ output
of the main mix. Use this to drive an external power amp.
This same signal is also being fed to the internal power
amplifier.
16. TAPE IN-OUT RCA JACKS
The RCA IN jacks are Ideal for pluggng in keyboard, cas-
sette deck or CD player. The LEFT/RIGHT TAPE OUT RCA
jacks deliver the main mix for recording (pre graphic EQ).
17. EFFECTS/FOOTSWITCH
Plug the optional FS22 footswitch into this jack to remote-
ly turn the effects ON or OFF.
18. SPEAKER OUTPUT JACKS
Connect the main speakers to these two 1/4” phone jacks.
A total of two 8Ωspeakers can be connected (one per
jack). Connecting 4Ωspeakers or more than two 8Ω
speakers will cause the mixer to go into “protect mode”
and mute the audio. The output relay will engage after 20
minutes of heavy use when using 4Ωspeakers.
19. POWER LED
The Power LED indicates when the mixer is powered up.
HELPFUL HINTS
1) FEEDBACK: To reduce feedback, the placement of the
speakers with respect to the microphones may need to be
reconsidered. As much as possible, try to have the main
speaker facing away from and in front of the microphones
not on stage behind them. The graphic EQ may be used to
reduce feedback from microphones.
2) NO HIGH FREQUENCIES: Check the channel tone con-
trols and EQ settings. The tweeters or midrange drivers may
have been damaged or blown from feedback or overpowering.
