JDS Labs C5 Amp or C5D Portable DAC/Amp
JDS Labs C5 Amp or C5D Portable DAC/Amp
Power Up
To get the most out of your top of the line headphones or inner ear monitors, you need more than just the audio jack on your iPod or computer. Bringing full power to your phones for full performance, the JDS Labs C5 Headphone Amp gives you a clean, balanced attack with multiple customization options. For even higher source performance, we are also offering the C5D Headphone Amp and DAC combination.
Adjustable Amp
Running off clean power, the C5 features TPS7A4700 and TPS7A3301 regulators that achieve a constant output of +/- 7 V for minimal distortion. The internal signal path is purely resistive for reference quality THD and frequency response performance. If you need to alter the sound, dual gain levels and a multi-position bass boost toggle allow you to change settings on the fly. As for the volume adjustment, the digital stepped attenuation in single decibel intervals results in smooth volume control at all levels, even with your sensitive monitors.
Throw Some D’s
Operating from a 1200 mAh Li-Ion battery, the C5 charges in 2-4 hours and runs for 11-14 hours. The C5D adds an asynchronous DAC, charges in the same time, and runs for 7-12 hours. In addition to amplification, the C5D converts your digital audio to an optimal 2V line-level output. Operable with Apple iOS7 devices and all UAC1 compatible operating systems,the C5D boasts ultra low jitter and impedance, resulting in natural frequency response with all headphones.
