Congratulations on the purchase of your mixer. Your new Concert Series
mixer demonstrates CARVIN’s commitment to producing the highest qual-
ity and most sophisticated engineering in the audio industry today. The
“C” series mixers are designed to be professional mixers for use in live per-
formance sound reinforcement systems. Features include a full function
stereo mixer with two nine band graphic equalizers. Exclusive features include
grouped phantom power and internal 24 BIT stereo digital effects. The high
quality construction will provide years of performance in and out of the studio.
Enjoy your new mixer.
OVERVIEW
The MIC/LINE input channels feature Balanced XLR and TRS 1/4” inputs with grouped phan-
tom power for condenser mics. There are 3 bands of EQ with a MID SHIFT and LOW CUT,
2 post fader effect sends, and 2 monitor pre-fader sends on each channel. The master sec-
tion features two 9 band graphic EQs, master stereo main and monitor mix controls, a mono
main control, a complete 16 program effects processor with send and return controls that
allow the effects to be heard through the main mix and monitor mix, and stereo external
effects returns.
CHANNEL EQ WITH ACTIVE TONE CIRCUITS
The Concert Series incorporates 3 bands of EQ per channel. They offer smooth non inter-
active tone curves so your adjustments will sound natural and yet be effective. The high
(treble) and low (bass) “shelving” type controls cover the complete upper and bottom por-
tions of the audio range. The LOW CUT switch provides instant elimination of unwanted
low frequencies below 75 Hz. The MID EQ controls are a “band pass” type which peak at
2.5k Hz or 700 Hz (depending on the MID SHIFT switch) for added presence to your mid
range tones . Because CARVIN uses “active” tone circuits, you are able to boost or cut your
tones without any signal loss to your sound.
RECEIVING INSPECTION—read before getting started
INSPECT YOUR MIXER FOR ANY DAMAGE which may have occurred during shipping.
If any damage is found, please notify the shipping company and CARVIN immediately.
SAVE THE CARTON & ALL PACKING MATERIALS. In the event you have to re-ship your
unit, always use the original carton and packing material. This will provide the best pos-
sible protection during shipment. CARVIN and the shipping company are not liable for
any damage caused by improper packing.
SAVE YOUR INVOICE. It will be required for warranty service if needed in the future.
SHIPMENT SHORTAGE. If you find items missing, they may have been shipped sepa-
rately. Please allow several days for the rest of your order to arrive before inquiring.
RECORD THE SERIAL NUMBER on the enclosed warranty card or below on this manual
for your records. Keep your portion of the card and return the portion with your name
and comments to us.
INTERNAL SIGNAL ROUTING
A balanced mic or instrument plugs directly into the high quality XLR Neutrik™ connectors
and is then routed into the differential circuits for excellent hum and noise cancellation.
As your signal continues within the console, a double-sided printed circuit board (FR-4
fire rated) carefully guards the circuit traces with a copper shield running over the traces.
This reduces RF interference and crosstalk substantially. The printed circuit board has
plated-through holes which means that every component is soldered securely in three places
(on the bottom, in the hole and on top). This offers unsurpassed component security while
reducing circuit resistance for pure dynamic sound.
HEADROOM
Headroom is very important when designing a mixer—especially for recording. Lack of head-
room will cause your sound to become distorted and muddy. This can happen when you turn
the volume too high, the input signal is too hot or excess EQ is added. With most mixers, you
have to reduce the input gain to fight headroom problems, but this just increases noise. That’s
why we have taken great care in the “C” series to make sure that each gain stage is properly
designed and balanced for more headroom along the entire audio path.
SWITCHING POWER SUPPLY
The Concert Series power supply offers unsurpassed rejection of noise and hum while
providing precision voltage for all preamp stages. The internal switching power supply
takes the 60 Hz AC line input and immediately converts it to 100kHz well outside of the
audio range. The 100kHz AC is sent through a transformer and converted to precision
DC voltages. Now you can go anywhere and never worry about inconsistent sound due
to fluctuating voltages because your mixer automatically switches internally to use 120
or 240VAC. (120VAC & 240VAC compatible with the proper AC cable) CARVIN has spared
no expense to achieve the best possible quality & performance.
