User manual CARVIN CX1272

[. . . ] This symbol is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN This symbol is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. LIMITED WARRANTY Your Carvin product is guaranteed against failure for 1 YEAR unless otherwise stated. Carvin will service and supply all parts at no charge to the customer providing the unit is under warranty. Carvin assumes no responsibility for horn drivers or speakers damaged by this unit. This warranty does not cover, and no liability is assumed, for damage due to: natural disasters, accidents, abuse, loss of parts, lack of reasonable care, incorrect use, or failure to follow instructions. [. . . ] The line input can be used at the same time the mic input is being used. 5 4 3 2. XLR MICROPHONE INPUT The XLR Mic input is designed for balanced low impedance (microphone) input signals. The differential balanced input amplifier reduces the common noise picked up on the microphone cables. 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). Phantom power is available on every XLR input jack when the phantom power switch in the master section is pressed. This feature allows condenser microphones to be run directly from the mixer. Note: When using phantom power, make sure the phantom power is switched off before connecting or disconnecting microphones to the mixer. It is recommended to allow 5 seconds for the phantom power to discharge before making any microphone connections. Also, to avoid hearing a pop, turn down the master volume when turning on the phantom power. 2 1 3. +20DB GAIN SWITCH The gain switch increases the input sensitivity on both the line and mic input jacks by 20dB. After determining the input is too low for mixing with the level control, turn down the level control, press in the gain switch, and adjust the level again. If distortion is heard regardless of the channel level control's setting, disengage this switch to eliminate over-driving of the input amplifier. the center position the channel is heard equally in both the left and right main outputs. Then if stereo placement is needed, a quarter turn to the desired side from the center position gives a smooth placement in the stereo field, or if desired a full turn to one side gives a hard placement. 12. POWER AMP INPUT SELECTOR The Power Amp selector selects the inputs to the two graphic EQ's and the power amplifiers. In the push in position the main left/right signals are combined to produce one mono signal (still controlled by the MAIN control). This mono signal becomes the input signal to the left EQ (top EQ) and the left power amp. Also, in the in position the output of the monitor jack and control knob becomes the input signal for the right EQ and right power amp. 7. CHANNEL EFFECTS 1&2 LEVEL CONTROL The EFF 1&2 control adjusts the volume of the channel going to the internal effects Send 1 master control, and directly to the EFF SND 2 output. The effects control is post-channel level and automatically tracks the channel's level & tone controls. 13. MONITOR MASTER LEVEL CONTROL The Monitor master level control is the master volume for the monitor mix heard in the monitor output. This volume receives its signals from the channel monitor level controls. CHANNEL LEVEL CONTROL The Level control adjusts the final volume of the channel before 8-10. [. . . ] This power is used for supplying a bias voltage to condenser microphones. INSERT JACKS The Left/Right INSERT jacks are pre-graphic EQ, pre-power amp, and normalized to the stereo mix L/R MAIN level control. When a STEREO LIVE SOUND SYSTEM In a live sound reinforcement or a public address system (P. A. System), the input signals to the mixer will come from the microphones and instruments on the stage.
