CARVIN ENGINEERING DATA C844, C1644(P), C2444, C3244 4-BUS MIXER OPERATING MANUAL

C1644P REAR PANEL FEATURES:

1 & 2. SPEAKER OUTPUTS

The 1/4” JACK (1.), and TWIST-LOK JACK (2.) of each amp are wired in parallel.

The minimum load for each amp is 4 OHMS. Chaining together more than one speaker on an output is fine as long as the total impedance is not below 4 ohms. If the speaker load is lower than 4 ohms, the amp may go into one of the PROTECT modes. (Two 8 ohm speakers in parallel = 4 ohms) 12 Gauge TWIST- LOK speaker cables are an industry standard for high power applicattions (pin 1+ is POS, pin 1- is NEG, pins 2+ and 2- are not used). The 1/4” jacks are used for lower power applications. Use only 16 gauge (or heavier) speaker cables, NOT shielded instrument cables. Turn power off before connecting speaker cables.

“OUT” position turns on front L/R speakers

3.AMP ROUTING switch will select between two internally routed configurations: OUT postion: AMP1-LEFT,AMP2-RIGHT,AMP3-MONITOR1,AMP4-MONITOR2

IN position: 1 amp each, for Monitors 1 thru 4.

Speaker output levels are adjusted from the Left/Right faders or Monitor 1-4 controls. The front panel GRAPHIC EQs function with the amps, depending on the front panel EQ1 and EQ2 switch settings.

4.AMP PATCH INSERT jacks offer full flexibility for mixer to amp signal routing. These jacks are T-R-S(Tip-Ring-Sleeve). Tip is the power amp input. Ring is the signal sent from the mixer determined by the AMP ROUTING switch. The limiters are post insert. Patching a compressor or equalizer between the mixer and the amp can be done by using a stereo insert cable (like Carvin’s AP1). Connect the RING signal to the INPUT of the external device, and the TIP signal from the OUTPUT of the device. Plugging in a standard 1/4” cable (mono) into the AMP PATCH INSERT jacks allows any external signal to be sent to the internal power amps.

***DO NOT USE A BALANCED CABLE***

For example, you may want to patch the GROUP outputs (1-4) into the power amps. -Plug one end of each cable into the GROUP jacks on the top panel of the mixer. -Plug the other ends of the cables into the AMP PATCH INSERT jacks.

The GROUP 1-4 faders will now control what is heard at the SPEAKER OUTPUTS.

C1644P FRONT PANEL INDICATORS:

5.AMP CLIP LEDs - The red CLIP LEDs will flash when the particular amp has reached it’s maximum output. Occasional flashing caused by bass frquencies is OK. Consistent flashing caused by higher fre- quencies may damage drivers due to excessive distortion. This will not damage the amp.

6.PROTECT LED - The yellow LED indicates the power amp system has gone into one of its protection modes. There will be no output from the amps. If the amp output has been short circuited, or overloaded by putting less than 4 ohms on the output the amp will go into protection. Check for shorted speaker cables and speaker impedance, then reset the POWER switch (off-on). If the amp has overheated, lower the volume and make sure the fan vents are not blocked. Wait for the fan to cool the amps. Normal oper- ation will return in about 1-3 minutes.

C1644

CONCERT 44 SERIES The C844, C1644(P), C2444 and C3244 feature 8 to 32 channels with true 4- bus performance. The C1644P adds four 300 watt power amplifiers built into our ROAD WARRIOR case. Never before have so many features been packed into such a rugged, compact USA made mixer. The best feature of the Concert 44 Series is the sound. Sound that is pure and quiet enough for digital recording studios. Everything is logically laid out making the powerful features simple to use. The knobs have been located so that adjust- ments can be made quick and easy with visible pointers showing you the status of your mix at a glance.

TRUE 4-BUS DESIGN The Concert 44 Series offers increased mixing flexibility over standard stereo con- soles by letting you assign channels to one of the 4 sub groups or L/R. This allows you to mix the entire drum, horn, choir, etc. into one sub group, which feeds the L/R faders. This is an easy way to control the volume of grouped mics and inputs. If you don’t need subgrouping, you can depress the L/R channel button and the channel goes directly into the L/R output like a standard stereo console. All 4 sub group outputs have bal- anced outputs for long cable runs.

TWO EFFECT SENDS / TWO 24-BIT EFFECT PROCESSORS Two built-in24-Bit effects, each offering 256 stereo effects, is a first in a 4-bus mixing console. Since there are two, you no longer have to choose between that great vocal reverb with delay and that awesome guitar chorus - you can have both! Each processor offers lush REVERBS, rich CHORUSES, thick textured FLANGING and pristine ECHOES with fully adjustable parame- ters for damping, decay, depth, speed, time and regeneration. Both processors can be sent back into the moni- tor mix so the performers can hear exactly what the audience is hearing.

FOUR MONITOR SENDS Every channel has 4 MONITOR sends with MASTER output level controls. Monitor

send jacks are balanced TRS.

3 BAND EQ/MID SWEEP The superb EQ system gives extended 15 dB boost and cut tone shaping. The LOW frequency control builds bass starting with 20 Hz through 80 Hz for a solid non-flabbylow-end. The exclu- sive offset of the MID FREQ. control ends the confusion of selecting your mid frequency from 100 Hz to 5kHz. The MID cut and boost control adjusts the gain to the perfect mid-dip or boost curve to enhance all instruments and vocals. The 11.5k Hz HI treble control adds sparkle to your top-end without adding harshness. Both the LOW and HI are “shelving”, which means they are effective from 20 Hz and up to 20k Hz. The LO CUT switch eliminates stage rumble or other unwanted low frequencies that would normally rob power from your woofers.

CHANNEL FEATURES Every channel has a full balanced XLR and LINE (1/4”) preamp with an INSERT jack for a compressor or EQ that also serves as a DIRECT OUT when plugged half way. The PAN con- trol directs the channel into the L/R output or any of the 4 sub groups after depressing the appropriate ASSIGN switches. A PFL (pre fader listen) switch allows you to hear the channel in the headphones before the fader is turned up. A solid “on” condition of the PEAK LED indicates that the MUTE switch has been activated which turns the channel off including all monitor and effect sends. When flashing during use, the PEAK LED also lets you know when to adjust the channel’s GAIN control to prevent chan- nel cliping. The SIGNAL LED lets you know that a signal is coming through the channel starting at –20 dBu. A silky smooth 60mm audio taper FADER delivers professional fade-outs. The PHANTOM power switches provide power through the XLR connectors for use with condenser mics like the Carvin CM90E in groups of 8 channels.

MASTER FEATURES Each of the 4 SUB GROUP faders can be switched to the R/L outputs or used independently through their own balanced output jacks. Each of the sub group’s PFL switches allow you to listen to the sub groups in your headphones before it is turned up. The R/L MAIN output faders are independent for added flexibility over a single stereo fader. A MONO control sums both the R/L outputs together (pre-graphic EQ) for a center, side fill or subwoofer output. The stereo HEADPHONE control tracks the METER switches which allow you to look and listen from the L/R, MONO, MONITOR 1/2 and 3/4 outputs and channel PFL switches. The master section also features 2 EFFECT SENDS, 4 RETURNS and RCA TAPE IN/OUT jacks. All 4 SUB GROUPS, 4 MONITORS, XLR L/R and MONO outputs are bal- anced. A FOOT SWITCH jack turns both effects processors on or off remotely with the optional FS22 foot switch.

SWITCHING POWER SUPPLY Our exclusive 125k Hz switching power supply eliminates trans- former noise. Like a laptop computer, go anywhere in the world and not worry about power because you can run on any voltage from 90 to 250VAC. (except C1644P)

SUPERB SOUND State-of-the-art low impedance, low noise preamps are featured on every channel. The balanced common mode rejection is better than 70 dB to eliminate cable noise. All main outputs are balanced to guard against system noise. The near theoretical limit on distortion has been achieved with THD below .01% to guarantee the purity of your sound, ensuring it will be dynamically open and transparent.

ENGINEERED TO LAST Hidden deep in the heart of these San Diego, CA made mixers is the SMT con- struction that utilizes surface mounted components to prevent malfunctions caused by vibrations. Sealed controls and switches guard against the outside elements while heavy-duty jacks provide a positive con- nection to your cables. Fire retardant FR-4 military spec circuit cards feature double-sided copper to elim- inate radio frequency interference. Precision 1% tolerance components guarantee your settings will be accurate every time. The Concert 44 Series is built to strict standards.
