CARVIN ENGINEERING DATA C1600 16CH & C2400 24CH STEREO MIXER OPERATING MANUAL 12340 World Trade Drive, San Diego, CA 92128 (619) 487-1600 (800) 854-2235 www.carvin.com Congratulations on the purchase of your mixer. Your new Concert Series mixer demonstrates CARVINÕs commitment to producing the highest qual- ity and most sophisticated engineering in the audio industry today. The ÒCÓ 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. OVERVIEWThe MIC/LINE input channels feature Balanced XLR and TRS 1/4Ó 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 CIRCUITSThe 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) ÒshelvingÓ 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 Òband passÓ 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 ÒactiveÓ tone circuits, you are able to boost or cut your tones without any signal loss to your sound. RECEIVING INSPECTIONÑread before getting startedINSPECT 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 ROUTINGA balanced mic or instrument plugs directly into the high quality XLR Neutrikª 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. HEADROOMHeadroom is very important when designing a mixerÑespecially 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. ThatÕs why we have taken great care in the ÒCÓ series to make sure that each gain stage is properly designed and balanced for more headroom along the entire audio path. SWITCHING POWER SUPPLYThe 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.

C1600 & C2400 CONTROLS CHANNEL FEATURES 1. 1/4Ó LINE IN The line connectors are for connecting balanced and unbal- anced instruments, mics, and line level sources such as drum machines or keyboards. 2. XLR MIC INThe balanced Mic inputs are for connect- ing microphones that use XLR connections. 3. CHANNEL INSERT/CHANNEL DIRECT For inserting channel effects, compressor, ETC. Or, as a direct output for multi-track recording. For a direct out use a 1/4Ó TRS (Tip Ring Sleeve) phone jack. To achieve a direct out from the channel insert to the first ÒclickÓ (1/2 insert).4. GAIN CONTROL Adjusts the GAINwhen connecting various instruments & mics. The type of mic (uni-directional, omnidirectional, etc) and model will require GAINsettings for each individual mic. Monitor the GAINlevel with the PEAK LEDs. If an LED is con- stantly illuminated decrease the amount of GAIN. Too much GAINmay cause distortion. If distortion is present, decrease the amount of GAINuntil the distortion is eliminated. 5. LOW CUT SWITCH 75 Hz low cut filter helps eliminate unwanted low frequen- cies from any particular channel. Great for reducing ÒboomÓ noise from mic stands or from acoustic/electric guitars. This filter can also help punch up the bass by turning up the LOW tone control while using the LOW CUTswitch.6. MID SHIFT SWITCH An exclusive feature giving you two different midrange center frequencies. This is ideal for vocals and/or instruments. The MIDtone switch on each channel is easier to use than con- ventional sweep controls because they allow you to compare for the best vocal or instrument sound by switching between the two MID frequencies. 7. ACTIVE 3 BAND TONE CONTROLS The C series mixers provide studio quality tone controls with distortion less than .009%Ðexceptionally clean for record- ing & live sound. The ±15 dB boost or cut give an overall 30 dB range for powerful EQ control. The active circuits deliver deep bass from the 20-80 Hz LOWcontrol. The MIDcontrol works in the 2.5k Hz range or the 700 Hz range depending on the MID SHIFT switch. The HIcontrol functions at 11- 20k for crisper highs. Start out with all tone controls at their center zero position. Determine which position your MID SHIFT sounds best at,then cut or boost your HI, MID and LOW frequencies for each as needed. If you are trying to mic instru- ments such as acoustic guitar or drums, try various mics and mic placement before adjusting your tone controls (condenser mics work well for these applications). Cutting and boost- ing frequencies improperly can cause an Òun-naturalÓ sound to your vocals or instruments. Your goal is to achieve a nat- ural sound for your entire performance or recording. 8. & 9. MONITOR 1 AND 2 CONTROLS Separate MONITOR level controls for each channel allows you to create two independent monitor mixes. The MONITOR sig- nals are routed to the master MON 1 & 2 faders respectively before going to the MONITOR output connectors. The mix you create with the MON 1 & 2 controls can also be heard C1600 & C2400 1 2 3 4 7 8 9 10 11 12 1314 15 16 17 5 6 QUICK START UP If youÕre like most new owners, youÕre 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: 1. CONNECTING AC POWER TO YOUR MIXER¥ The mixer can be used with 120 or 230VAC (it automati- cally switches internally) ¥ Use only a grounded (3 prong) power outlet to prevent a shock hazard. This gives the quietest grounding for your mixer. 2. CONNECTING INPUTS TO YOUR MIXER¥ For low level balanced devices such as microphones, plug into the balanced MICinputs using a shielded microphone cable with XLR ends.¥ For high level unbalanced devices such as instruments & Keyboards, plug into the LINEinput jacks using a shielded cable with 1/4Ó phone plugs. Adjust the GAINknob for the mic or line input being used. 3. TURNING YOUR MIXER ON¥ Adjust all channel FADERS and master LEVELcontrols to their OFF positions ¥ Adjust all channelÕs HI, MID, and BASScontrols and the two master 9 Band Graphic EQÕs to their center position. ¥ Adjust all the Channel ÒPANÓcontrols to their centerposition. ¥ Turn the mixer on by the rear panel POWER SWITCHand watch for the POWERLED to come on. Your mixer is now ready to operate.
