EQ230 / EQ430 Operation 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, 4

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 2x24 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.
