CARVIN PA1200 User manual

CONGRATULATIONS on your purchase of Carvin’s PA800, PA1200 or PA1200R Series
mixer! The "R" version is a non-power rack model designed for your own power amp while the
PA800 and PA1200 models included built-in high power amplifiers for direct hook-up to your
speakers. Please read this manual carefully to take all the advantages of your new mixer.
SUPERB SOUND is derived from the extremely low distortion, high "Headroom" design.
A state-of-the art, low noise, high headroom, balanced XLR preamp for each channel features
a common mode rejection of better than 78 dB, which means that any possible noise that may
come over your cables is virtually eliminated. Even the balanced XLR output connectors guard
your system from cable noise for professional recordings or external power amp connections.
Distortion is nearly non-existent with THD below .1%, which guarantees the purity of your
sound. Hear the difference - your sound will not seem "sterile" or "processed". It will be
dynamically open and transparent just like it was meant to be!
LIGHT WEIGHT and EASY TO USE everything is logically laid out making the PA
Series simple to use, which helps to eliminate operator error. Its compact size and weight of
28 lbs. makes it the lightest, most powerful mixer of its kind. No other competitor in the
industry offers a higher performance to weight ratio!
3 HIGH CURRENT AMPLIFIERS deliver 333 watts RMS each. A total of 666 watts is
delivered to your main speakers (333 watts each for the R/L if played in stereo), plus a 333
watt amp to drive your stage monitors for a total of 1000 watts. This is the kind of output
required for today’s professionals to maintain purity and integrity of sound. Six output jacks,
two from each amp, deliver full power into 4 ohms, making these mixers more powerful than
most amplifiers rated at 2 ohms. A peak indicator for every amp and a protect LED gives you
a visual monitor.
A HIGH CURRENT POWER SUPPLY is provided by a beefy toroid transformer to
assure continuous high amperage DC voltage to all three power amplifiers, eliminating "overload"
or shutdown. 20,000 mfd capacitors offer a large power reservoir for bass thumping output.
The PA1200R features a 125k Hz switching power supply for operating your mixer at any volt-
age from 90 VAC to 240VAC. Like a laptop computer, you can go anywhere in the world and
not worry about power adapters.
2 INDEPENDENT 24-Bit STEREO DSP EFFECTS allow you to assign each chan-
nel to your choice of effects. You can dedicate chorus/rev to the acoustic guitar channel and
reverb to the vocals, etc. Both effects are adjustable to your stage monitors so you can hear
yourself with full effects. The effects processors with 256 effects each, include reverbs, cho-
ruses, flanging and echoes, with parameters fully adjustable for; damping, decay, depth,
speed, regeneration and time.
ACTIVE 3 BAND CHANNEL EQ provides easy adjustment for the tone you want. The
LO frequency controls starts at 20 Hz and continues through 80 Hz for a solid non-flabby bass.
A simple adjustment with the MID band, gives you the best sound for vocals or guitar in the
very important 750Hz frequency range. The 11.5k Hz HI treble control adds sparkle to your
top-end without adding harshness. Both the LO and HI are "shelving", which means they are
effective from 20Hz up to 20k Hz.
TWO 9 BAND EQUALIZERS provide precise 1 octave adjustments to fine tune your
over all sound and to help control feedback. Unlike one stereo graphic equalizer, two inde-
pendent 9 bands give you total flexibility. At the push of a button, you can assign both equal-
izers to the main and monitor speakers or to the L and R outputs.
ENGINEERED TO LAST Every PA Series mixer incorporates a rugged reinforced steel
chassis. Continuous full power is assured from a 370 sq inch, high-grade 6063-T5-aluminum
heat sink cooled by a quiet dual-speed fan. You’ll never have to worry about protect or power
reduction modes.

PA800, PA1200, PA1200R MIXERS
ENGINEERED TO LAST cont. Hidden deep in the heart of these mixers is the
“SMT” Surface Mount Technology construction that utilizes surface mounted com-
ponents to prevent parts from shaking or vibrating loose. Sealed controls and switch-
es guard against the outside elements while heavy-duty connectors provide a posi-
tive connection to your cables. Fire retardant FR-4 military spec circuit cards feature
double-sided copper construction to guard against noise and radio frequencies (RF).
Precision 1% tolerances guarantee that your settings will be accurate every time. The
multi-ply wood cabinet is not the typical heavy particleboard that can break or crack,
and the Duratuff covering is scratch and dent resistant. The PA Series is profession-
ally made in the USA for years of service!

PA800/1200/1200R MIXERS

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 instruc-
tions to get you going quickly. With the mixer unplugged and
the unit turned off, complete the following procedures:
A. CONNECTING AC POWER TO YOUR MIXER
• Be sure to plug your mixer into the proper voltage for your
country, either 120V-60Hz or 240V-50Hz. The PA1200R
accepts both voltages listed.
• Use only a grounded (3 prong) power outlet to prevent a
shock hazard. This gives the quietest grounding for your
mixer.
B. CONNECTING INPUTS TO YOUR MIXER
• For balanced microphones, use a shielded cable and plug
into the XLR MIC inputs.
• For high output devices like instruments & keyboards, plug
into the LINE input jacks using a shielded cable. Depress
the GAIN switch “IN” for mic or “OUT” for instruments.
C. TURNING YOUR MIXER ON
• Set all channel and master LEVEL controls to their OFF
positions
• Set all HI, MID, and BASS controls and the graphic equal-
izers to their center “flat - no boost or cut” position.
• Adjust all channel “PAN” controls to their center position.
• Connect your speakers and monitors at the rear panel.
• Turn the mixer on by the rear POWER SWITCH and watch
for the front POWER LED to come on. Your mixer is now
ready to operate by turning the levels up.
MIC CHANNEL FEATURES
1. LINE INPUT JACK
The LINE input is a 1/4” phone jack designed for balanced or
unbalanced line or instruments. Examples of these inputs
would be guitar, keyboard or CD player. The line input can be
used at the same time the mic input is being used.
2. XLR MICROPHONE INPUT
The XLR MIC input is designed for balanced low impedance
microphones. The high performance, low noise preamps do
a superb job of noise reduction. 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). Note:
Make sure the phantom power is switched off before con-
necting or disconnecting microphones to the mixer. It is rec-
ommended to allow 5 seconds for the phantom power to dis-
charge before making any microphone connections.
3. GAIN SWITCH
The GAIN switch increases the input sensitivity on both the
LINE and MIC input jacks by 20dB. Depress the GAIN switch
“IN” for mic or “OUT” for instruments. If distortion is heard,
the input source is overdriving the input stage. Disengage
the GAIN switch to the “OUT” position.
4. CHANNEL LEVEL CONTROL
The LEVEL control adjusts the volume of the channel before
going to the PAN control. Here is where the individual chan-
nel volumes are adjusted to make up the desired mix at the
main outputs. A general rule to prevent internal overdriving,
is to keep the MAIN master LEVEL the same or higher than
the channel LEVEL.
5. MONITOR LEVEL CONTROL
The MON level control adjusts the volume of the channel
going to the master monitor send. The monitor level control
is a pre-channel level control. This means it is unaffected by
adjustments from the channel level. The purpose for this is
the main mix adjustments can be made without disturbing
the monitor mix.
6. CHANNEL PAN CONTROL
The PAN control puts the channel into the LEFT, RIGHT or
CENTER in the stereo main outputs. If stereo placement is
needed, set the PAN control to the full RIGHT or LEFT position.
7. CHANNEL EFFECTS 1&2 LEVEL
The EFF 1&2 adjusts the level sent to the dual effects proces-
sors and to the EFF SND 2 jack. The effects control is post-
channel level, which automatically tracks the channel’s
LEVEL & tone controls. Turning this control to the left will
send to the internal effects processor 1. Turning to the right
will send to the internal effects processor 2 (and the external
EFF 2 SND jack). Reduce these levels if PEAK LEDs are flash-
ing on the effects processors.
8-10. CHANNEL TONE CONTROLS
Each channel features active 3-band tone controls LO, MID,
and HI. All three function as boost (clockwise) & cut
(counter-clockwise) controls. The center 0is the “flat” or no
effect position. The LO and HI controls are shelving type
with corner frequencies at 80Hz and 11.5k Hz respectively.
The MID control is a band pass type centered at 750Hz.
Recommended setting: LO & HI +4, MID at -4. For electric
guitar, set the MID at -6 to -12 to add clarity.
MASTER SECTION FEATURES
11. MAIN MASTER LEVEL (AMPS 1&2)
The MAIN control is the master volume control for all chan-
nels. The MAIN signal is sent to the GRAPHIC EQ that feeds
the power amps and the RIGHT and LEFT XLR output jacks.
12. MONITOR MASTER LEVEL (AMP 3)
The MONITOR master level is sent to the GRAPHIC EQ (if
switched “IN”) and feeds the MONITOR power amp 3 and
XLR output jack.
13. EFF 2 SEND JACK
The EFF 2 SEND jack can send a signal to an external proces-
sor. This is the same signal sent to the internal EFF 2 processor.
14. RETURN LEVEL & L-R RETURN JACK
The RETURN level control and L-R jack provides another
input into your mixer. It is most commonly used for an out-
board effects processor returning the signal from the EFF 2
SND, or as another input from a stereo source or instru-
ment.
A stereo TRS (Tip, Ring, Sleeve) cable will send the Tip signal
to the Land the Ring signal to the R. Inserting a mono plug
partially (first "click") will send a mono signal to both L-R.
15. L-R XLR OUTPUT CONNECTORS
The L-R professional balanced XLR line outputs are post
graphic EQ connectors. Use these to feed additional power
amps or recording gear. Note: If the INSERT jacks are being
used for patching, the new signal will be present.
16. MONITOR XLR OUTPUT CONNECTOR
This line output is the same signal that feeds the internal
MONITOR AMP 3. Use this professional balanced XLR out-
put for additional power amps.
17. PRE EQ INSERTS 1 AND 2
These jacks allow you to inject a signal into the master sec-
tion of the mixer. This insert is before the GRAPHIC EQ
using a stereo (tip ring sleeve). The TIP is the SEND and the
RING is the RETURN. The typical use of these jacks are for
the insertion of a compressor or other outboard gear
between the master preamp and the EQ. If a mono plug is
inserted into these jacks, the channels are disconnected
from the power amps.
18. TAPE JACKS
The L-R TAPE IN RCA inputs are ideal for connecting a CD or
tape player. These TAPE IN jacks can also be used for returning
another stereo effects processor or instrument (keyboard).

18. TAPE JACKS CONT. The L-R TAPE OUT RCA
jacks sends the MAIN signal (pre graphic EQ) for recording.
If the TAPE OUT is being used to record, make sure the
TAPE IN control is turned OFF to avoid feedback. The TAPE
OUT jacks are another way to access the output of the mas-
ter section if the INSERT jacks are being used.
19. DSP PROCESSORS
Two 24-Bit proces-
sors provide a host of
great sounding
effects including
Flange, Reverb, Echo,
& Chorus. The chan-
nel EFF 1&2 send
controls delivers the
signals to the dual processors. Note: Reduce these levels if
the red PEAK LEDs are flashing on the processors.
Turn up the EFFECTS control to 5 on the processor(s) to add
your effects, while at the same time adjust the SELECT and the
PARAMETER controls to get the desired effect. Note: An audi-
ble noise will be heard while adjusting the effects.
EFFECT PARAMETERS
Each of the four effects has a variable parameter that can be easily
adjusted. Each “SELECT” & “PARAMETER” is described below.
A) ECHO: SELECT the amount of the regeneration (repeat-
ing). Now select the PARAMETER control for the shortest or
longest delay time between the original signal and the echo.
B) REVERB: SELECT the amount of presence (high frequen-
cies) in the reverb. Now turn the PARAMETER control to pro-
vide the minimum or maximum decay.
C) CHORUS: SELECT the amount of reverb with your chorus.
Now turn the PARAMETER control to increase the depth.
19. DSP PROCESSORS CONT. D) FLANGE: SELECT
the amount of speed with your flange (phasing effect). Now
turn the PARAMETER control to increase the depth.
20. DSP PK 1, PK 2 LED’s
The DSP PEAK LED indicates that the signal level to the
processor is too high. To prevent distortion, turn the EFF 1-2
control towards the center (off) position until the PEAK LED
stops flashing.
21. EFF TO MONITOR CONTROL
The EFFECTS TO MONITOR level controls the amount of the
effects that goes into your monitors.
22. TAPE IN LEVEL
You may use the TAPE IN level as another input into your
mixer using the RCA TAPE IN jacks.
23. AMP “CLIP” LED’s
The amp CLIP LEDs indicate when the power amps are
starting to distort (clip). Reduce the MAIN 1-2 and/or
MONITOR 3 master volumes to prevent distortion.
24. POWER LED
The Power LED indicates when the mixer is powered up.
25. PROTECT LED
The mixer will “protect”, engaging relays to mute the speak-
ers if: a) impedance is below 4Ωon any amplifier b) short-
ed speaker cables, or c) ventalation problems. If this LED
comes on, shut the mixer “OFF” and check for cable prob-
lems, proper impedance and obstructed rear cooling vents.
If you encounter an over-heat problem, leave the mixer
“ON” allowing the fan to cool down the internal compo-
nents. The mixer will auto-reset. If a problem persists,
please contact Carvin’s service dept. 800-854-2235.
26. GRAPHIC EQUALIZER SWITCH
The EQ button will switch the EQ’s from LEFT-RIGHT to
MONO/MONITOR. The “OUT” position puts both EQ’s in the
L-R MAIN mix only. EQ1 is for the LEFT amp and EQ2 is for
the RIGHT amp. The “IN” position will combine the L-R mix
into EQ1 as a mono mix. Then the monitor mix is routed
through EQ2 for use with the MONITOR 3 amp to help control
stage feedback.
27. ADJUSTING THE GRAPHIC EQUALIZER
When the EQ sliders are in their center position, they do not
affect the audio signal. When EQ sliders are raised or low-
ered from this position, they boost or cut respectively a nar-
row frequency band. To reduce feedback in the low fre-
quency range, try lowering one of the 63, 125 or 250 Hz
sliders. High frequency feedback is reduced by lowering
one of the 2k or 4k Hz sliders.
To help with feedback reduction, the main speaker should
always be placed in front of the microphones.
For tone enhancement you may want to raise the 63, 125 (for
deeper bass)
and the 4, 8 and
16k (for crisper
highs) forming
a “smile” curve
as shown.
28. EFFECTS FOOT SWITCH JACK
The optional FS22 will remotely
shut off EFFECTS 1 or 2.
29. 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 voltage to condenser microphones.
The LED indicates the phantom power is turned on. The
phantom power will not damage conventional dynamic
microphones. Note: Make sure the phantom power is
switched off before connecting or disconnecting micro-
phones to the mixer. It is recommended to allow 5 seconds
for the phantom power to discharge before making any
microphone connections.
REAR PANEL-POWER/SPEAKER CONNECTIONS
The rear panel contains the POWER SWITCH and AC power
cable connection. For the PA800 and PA1200, there are 3
groups of 1/4” speaker jacks. Each group has two 1/4” out-
puts (wired in parallel). AMPS 1 and 2are for the LEFT and
RIGHT speakers. AMP 3 is for the MONITOR speakers.
NOTE: 4ΩMIN IMPEDANCE PER AMPLIFIER (Maximum one
4Ωor two 8Ωspeakers per amp). MAKE ALL SPEAKER
CONNECTIONS BEFORE TURNING THE MIXER ON .
