Short Description:

It may be small, but the UB502 features the same state-of-the-art Invisible Mic Preamp (IMP) and the same Ultra low-noise (ULN) design for highest possible headroom as its larger brethren. Its one mono channel plus 2 stereo channels with a 2-band EQ on the mono channel make it ideal for use with fixed audio installations as well as keyboards, samplers and computer application. Hobby musicians and video makers will also find use for this ultra-compact mixer.


Features:

• Ultra low-noise ULN design, highest possible headroom, ultra-transparent audio
• 1 new state-of-the-art, studio-grade IMP “Invisible” Mic Preamp with:
- 130 dB dynamic range for 24-bit, 192 kHz sampling rate inputs
- Ultra-wide 60 dB gain range
- Lowest possible distortion 0.0007% (20 Hz - 20 kHz)
• Effective, extremely musical 2-band EQ and peak LED on mono channel
• 5 balanced high-headroom line inputs
• State-of-the-art 4580 operational amplifiers provide lowest noise and distortion—better than 4560 op amps
• Main mix outputs plus separate headphones and stereo tape outputs
• Tape inputs assignable to main mix or phones outputs
• High-quality sealed rotary controls from ALPS® for long-term reliability
• External power supply for noise-free audio and superior transient response
• Extremely rugged steel construction ensures long life even under the most demanding conditions
• Conceived and designed by BEHRINGER Germany
