CARVIN EQ200 Series Equalizer User Manual

CARVIN EQ200 Series Equalizer User Manual

The EQ230 and EQ430 with X-Drive™ processing are two and four channel precision 30-band graphic equalizers designed to elevate the performance of any system. The XD Network™ software with USB connectivity offers total control with the processing flexibility required for both installation and live use. The EQ230 and EQ430 are next generation tools for critical sound processing between the mixer and power amp.

The EQ X-Drive series can improve the sound of main speakers, monitor systems or multi-zone applications with exacting EQ adjustments, but also with reduced feedback, driver protection and time correction of speaker placement. Each channel includes 30 bands of 1/3 octave constant-Q filters, 4th order High- Pass and Low-Pass filters, Gain, Limiter with Threshold and Delays up to 120mS for distance alignments. System Presets allow storage and recall of your preferred settings to get the most out of each element in your system.

A high contrast 2×24 graphic display allows programming from the front panel. For remote settings, use the intuitive USB interface (see carvin.com/XD). Onboard memory capacity has enough storage to contain up to sixteen complete system EQ configurations, or store unlimited configurations on your PC or MAC. Premium 24-bit A/D and D/A converters offer low noise and full 20-20kHz bandwidth with extremely low latency processing. The EQ X-Drive series provide multi-channel EQ’s with an easy to use interface, high order AD/DA converters and first-rate components in a space and weight saving 1U package, making them a valuable addition to any rack.

SAFETY

IMPORTANT! FOR YOUR PROTECTION, PLEASE READ THE FOLLOWING:

CAUTION: RISK OF ELECTRIC SHOCK, DO NOT OPEN.

WATER AND MOISTURE: Electronic equipment should not be used near water (near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool, etc). Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through openings. POWER SOURCES: The electronic equipment should be connected to a power supply only of the type described in the operating instructions or as marked on the electronic equipment.

GROUNDING OR POLARIZATION: Precautions should be taken so that the grounding or polarization means of an electronic equipment is not defeated.

POWER CORD PROTECTION: Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles and the point where they exit from the electronic equipment.

SERVICING: The user should not attempt to service the electronic equipment beyond that described in the operating instructions. All other servicing should be referred to qualified service personnel. If your unit is equipped with a fuse receptacle, replace only with the same type fuse. Refer to replacement text on the unit for correct fuse type.

This equipment has been tested and found to comply with international safety standards.

Rear Panel

AC Power receptacle: A standard IEC that will accept 90-250 VAC, 50-60Hz.

Ground Lift switch: Lifts the signal grounds to solve ground loop issues in complex setups.

USB type B jack: For connection to a computer using Carvin’s XD™EQ software with a full screen graphic interface and for firmware updating.”

INPUTS 1 – 4, (XLR or 1/4”): Connect to audio sources.
OUTPUTS 1 – 4 (XLR or 1/4”): Connect to audio inputs.

DELAY:
The Delay time can be adjusted in large and small increments:
mS/uS (milliseconds/microseconds), Feet/Inches or Meters/mm. (change units in the UTILITY menu).
The total amount of delay available for the EQ230/EQ430 is 120 milliseconds (120ft./36.5M). Each time a delay is added, it deletes it from the total time available for the system. For example, a Stereo system may have up to a maximum of 60mS for each of the 2 channels.

HIGH PASS (HPF) and LOW PASS (LPF) FILTERS:
Use the filters to protect speakers from extreme frequencies beyond the speaker’s usable range. These are a 4th order (24dB/oct.) Butterworth filters.
HPF: Set the High Pass Filter frequency (Low Cut). The lowest setting is OFF.
LPF: Set the Low Pass Filter frequency (Hi Cut). The highest setting is OFF
