The Pioneer DDJ-REV1 is a basic DJ controller that incorporates an internal sound card, allowing you to connect it directly to your speakers or amplifier for audio output. The built-in sound card is designed to provide decent sound quality for typical DJing applications.
On the other hand, an external audio interface like the UA Volt 1 offers additional features and potentially higher audio quality. Audio interfaces are designed specifically for audio recording and production purposes, providing enhanced audio processing, better digital-to-analog and analog-to-digital conversion, and sometimes more robust connectivity options.
Whether investing in an external audio interface would improve the sound quality of your DJing setup depends on a few factors:
Sound Requirements: If you're DJing in small venues or casual settings where the primary concern is playing music, the built-in sound card of the Pioneer DDJ-REV1 should suffice. The sound quality from the controller's built-in sound card is generally adequate for such situations.
Audio Processing and Connectivity: If you require additional audio processing features, such as EQ, effects, or advanced routing options, an external audio interface may offer more flexibility. Additionally, if you need additional connectivity options, such as multiple outputs for separate speaker systems or recording capabilities, an audio interface might be beneficial.
Audiophile Considerations: If you have a discerning ear for audio quality or plan to use higher-end audio equipment, an external audio interface might offer better sound reproduction due to its dedicated components and improved conversion technologies. This would be more relevant if you're working in professional audio production or high-quality sound environments.
In summary, while the Pioneer DDJ-REV1's built-in sound card is suitable for most basic DJing needs, investing in an external audio interface like the UA Volt 1 could provide additional features and potentially improved audio quality. However, the extent of the improvement would depend on your specific requirements and the audio equipment you're using. It's recommended to consider factors like your DJing environment, desired audio processing capabilities, and personal preferences for sound quality before deciding whether an external audio interface would be worth the investment.
