CARVIN ENGINEERING DATA C1648, C2448, C3248, C1648P 4-bus MIXER OPERATING MANUAL

C1648 featuring 4-band EQ and 8 channel sends

CONCERT 48 SERIES The C1648(P), C2448, and C3248 feature 16 to 32 channels with true 4-bus performance. The C1648P adds four 500 watt power amplifiers. Never before have so many features been packed into such a rugged, compact USA made mixer. The best feature of the Concert 48 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 adjustments can be made quick and easy with visible pointers showing you the status of your mix at a glance.

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.

TRUE 4-BUS DESIGN The CONCERT 48 Series offers increased mixing flexibility over standard stereo consoles 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 channel L/R button and the channel goes directly into the L/R output like a standard stereo console. All 4 sub group outputs have balanced outputs.

4 COMPRESSORS Each of the 4 sub groups feature a studio-grade compressor to reduce the output when it gets above the level you set with the COMP control. Ideal for drums or horns.

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 vocal reverb or that awesome guitar chorus - you can have both! Each processor offers lush reverbs, rich choruses, thick textured flanging and pristine echoes with fully adjustable parameters for damping, decay, depth, speed, time and regeneration. Both processors can be sent back into the monitor mix so the performers can hear exactly what the audience is hearing.

SIX MONITOR SENDS Every channel has 6 MONITOR sends with MASTER output level controls and XLR balanced outputs.

4 BAND EQ/DUAL MID SWEEPS 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-flabby low-end. The LO MID and HI MID FREQ controls offer variable freqency settings from 45 Hz to 2kHz and 200Hz to 10kHz 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.

TWO 9 BAND EQUALIZERS Precision equalizers provide 1 octave adjustments to tune in your overall sound and control feedback. Unlike one stereo equalizer, two independent 9 bands offers greater flexibility. You can assign the EQs to the L/R outputs or to the monitor 1/2 outputs. Center frequencies are 63, 125, 250, 500, 1k, 2k, 4k, 8k & 16k Hz.

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 control directs the channel into the L/R output or any of the 4 sub groups after depressing the appropriate ASSIGN switches. The 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 channel distor- tion. 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 with dust cover delivers professional fade-outs. The PHANTOM power switches provide power through the XLR connectors for use with condenser mics like the Carvin M90S in groups of 8 channels.

MASTER FEATURES Each of the 4 Sub Group faders can be switched to the L/R 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 L/R MAIN output faders are independent for added flexibility over a single stereo fader. A MONO/SUB control sums both the L/R 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 1-6 outputs, USB IN, REC OUT/USB, and channel and group PFL switches. The master section also features 2 EFFECT SENDS, 4 RETURNS and RCA RECORD OUT jacks. All 6 MONITORS, L/R and MONO outputs are balanced XLR, while the 4 SUB GROUPS are balanced 1/4”.

SWITCHING POWER SUPPLY Our exclusive 125k Hz switching power supply eliminates transformer 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. The C1648P will automatically switch for 120VAC or 240VAC ranges.

ENGINEERED TO LAST Hidden deep in the heart of these USA made mixers is the SMT construction 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 connection to your cables. Fire retardant FR-4 military spec circuit cards feature double-sided copper to eliminate radio frequency interference. Precision 1% tolerance components guarantee your settings will be accurate every time. The Concert 48 Series is built to strict standards.
