Two Professional Single Channel DOD Model 431 (one Series II and one series SR Q XLR) 31-Band Graphic Equalizers. Excellent working condition. Made in the USA in 1995. Solidly made. Audiophile quality sound. Rack mountable. Although they are slightly different models, I cannot tell their sound apart. The XLR only accepts XLR and 1/2 connectors. The Series II accepts 1/2 and RCA plugs. All the indicator lights work. I wasnt able to get a picture of the red level indicator light without bursting my ear drums. So I did not attempt it. The Series II eq seems to have more gain than the XLR, perhaps because it uses a potentiometer instead of a slider. Their top covers were scratched up and faded. I had them professionally sand-blasted and powder-coated with Polished Aluminum paint (and a clear coat) last year. They both come with power cords. The XLR came to me with two broken sliders. My technician replaced them. They are a little longer than the original sliders. I sprayed all the sliders with DeoxIT F5 Fader cleaner and lubricant last night (01/22/25). The sliders slide smoothly and effortlessly. I have used these equalizers in my home audio system from time to time over the last 14 years. They will outperform and outlast most of the new Chinese made equalizers. They will be packaged well for safe shipping and delivery.

The DOD R-430 is a dual-channel graphic equalizer designed for both studio recording and live sound applications. It operates analogically and features 1/4 and RCA input and output connections per channel. It is rack-mountable, occupying a single space in standard rack systems. Ease of Use:Using the DOD R-430 is straightforward. It boasts a 15-band graphic EQ per channel covering frequencies from 25 Hz to 16 kHz, offering comprehensive spectrum coverage. Each channel includes a low-cut switch, in/out button, and output gain knob. Its simplicity makes a manual unnecessary. Sound Quality:The sound quality of the DOD R-430, while sufficient for most tasks, isnt particularly remarkable. It performs adequately in live sound reinforcement but may not excel in a studio recording environment where parametric EQs are often preferred for precise adjustments. The EQ controls effectively manage broad frequency ranges rather than pinpoint adjustments. The unit maintains a transparent sound profile, primarily altering audio only as adjusted, without adding significant coloration or enhancement capabilities beyond basic EQ modifications.
