Review ENTTEC Pre owned Dmxusb Pro Usb To Dmx Interface Controller

The **ENTTEC DMXUSB Pro (Model 70303, pre-owned)** is a robust and versatile USB-to-DMX interface controller designed for professionals in the lighting, entertainment, and stage production industries who demand reliability, flexibility, and seamless integration with modern digital systems. This pre-owned unit retains the core functionality of its original design, offering a direct bridge between DMX512-compatible lighting consoles, controllers, and fixtures with any computer running Windows, macOS, or Linux via a standard USB connection. Built with a focus on durability, the DMXUSB Pro supports full duplex communication at speeds up to 250 kbps, ensuring smooth data transmission for complex lighting setups, including addressable LED strips, moving lights, and traditional DMX-controlled fixtures. Its compact yet sturdy form factor makes it ideal for both studio and live performance environments, where space and portability are often critical. The interface supports a wide range of DMX addresses (up to 512 channels per fixture) and includes a built-in power supply, eliminating the need for external adapters while maintaining compatibility with most DMX protocols. Whether used for rehearsals, installations, or live shows, this pre-owned unit delivers the same professional-grade performance as its new counterparts, making it a cost-effective solution for those looking to upgrade their lighting control setup without compromising on quality. Its compatibility with industry-standard software like Lightkey, QLC , and DMX Control ensures broad applicability, while its pre-owned status provides an opportunity to acquire a high-performance tool at a reduced price, perfect for hobbyists, educators, or small-scale productions seeking reliable DMX connectivity.

**Pros and Cons of Buying a Pre-Owned Enttec DMXUSB Pro (70303)**

### **Pros**

1. **Cost Savings** A pre-owned unit is significantly cheaper than a new one, allowing you to acquire a high-quality DMX interface without the full retail price. The DMXUSB Pro is already a well-regarded device, and buying used can reduce costs by 30-50% or more.

2. **Same Performance as New** The DMXUSB Pro is a robust, solid-state device with no moving parts. As long as the unit is in good working condition, it will perform identically to a new one, with no degradation in functionality.

3. **Proven Reliability** The DMXUSB Pro has a strong reputation in the lighting and entertainment industry for stability and compatibility. Many users report years of trouble-free operation, making it a trusted choice for both beginners and professionals.

4. **Compatibility with Multiple Systems** The device supports DMX512, Art-Net, sACN (E1.31), and other protocols, making it versatile for different lighting control setups. This flexibility is valuable whether you're working with DMX consoles, software like QLC , or networked lighting systems.

5. **USB Connectivity** The USB interface is widely supported across operating systems (Windows, macOS, Linux), and the device is plug-and-play in most cases. This eliminates the need for additional hardware or complex installations.

6. **Lightweight and Portable** The DMXUSB Pro is compact and easy to carry, making it ideal for gigs, rehearsals, or small installations where space is limited.

7. **Good Resale Value** Since the device retains its value well, buying used ensures you can recoup a significant portion of your investment if you decide to upgrade later.

8. **Community and Support** The DMXUSB Pro has a large user base, meaning troubleshooting resources, firmware updates, and community support are readily available. Even if you buy pre-owned, you can still access official Enttec support for software-related issues.

### **Cons**

1. **No Warranty** The biggest drawback of buying pre-owned is the lack of a warranty. If the device fails shortly after purchase, you ll be responsible for repairs or replacements out of pocket. Enttec s original warranty typically covers defects for 1-2 years, so a used unit may have no protection.

2. **Potential Wear and Tear** While the DMXUSB Pro is durable, pre-owned units may show signs of wear, such as scuffed casing, loose cables, or minor physical damage. However, since it s a solid-state device, cosmetic issues rarely affect performance.

3. **Limited Testing History** You won t have the same level of confidence in the device s condition as you would with a new purchase. While reputable sellers (e.g., on eBay, Facebook Marketplace, or specialized forums) often provide testing or return policies, there s still an element of risk.

4. **Firmware Version Unknown** Older units may run outdated firmware, which could lack support for newer protocols or software. While Enttec occasionally releases updates, you ll need to manually check and install them if the seller hasn t done so.

5. **Seller Reliability** The quality of the transaction depends entirely on the seller. Some may be honest and transparent, while others might hide issues (e.g., intermittent connectivity, damaged ports). Always verify the unit s condition through testing or a trusted third party if possible.

6. **No Return Options** Most pre-owned sales are final, meaning you won t have the option to return the device if it doesn t work as expected. This adds risk compared to buying new from a retailer with return policies.

### **Ending Conclusion**

Buying a pre-owned Enttec DMXUSB Pro is a **strong financial decision** for those who prioritize cost savings without sacrificing performance. The device is inherently reliable, and the risk of failure is low especially if purchased from a reputable seller who offers testing or a brief return window. The lack of warranty is the most significant trade-off, but for many users, the savings outweigh this concern, particularly if they re confident in the unit s condition.

If you re working on a tight budget, need a backup controller, or are testing DMX for the first time, a pre-owned DMXUSB Pro is an excellent choice. However, if budget isn t a constraint or you want peace of mind, purchasing new ensures warranty coverage and immediate support.

### **Recommendation**

- You ve verified the unit works correctly (preferably with a test run or seller confirmation).

- You re comfortable with the lack of warranty and can assess the seller s reputation.

- You re buying from a trusted source (e.g., a well-reviewed individual, a lighting rental company, or a dedicated tech reseller).

- You plan to use it in a low-risk environment where failure isn t critical.

- You re unable to test the device before purchase.

- The seller refuses to provide any form of return or testing.

- You require warranty support for long-term reliability.

- The price seems unusually low, which could indicate hidden issues.

If you re unsure, consider buying new from an authorized retailer (e.g., Enttec s official store, Amazon, or specialty lighting suppliers) if your budget allows. Alternatively, look for a slightly older model (e.g., DMXUSB Basic) used, as it may offer better value while still meeting your needs.

For most users, the DMXUSB Pro s reputation and performance justify the risk of buying pre-owned, especially when paired with due diligence in selecting a seller.
