Connect your iPhone or USB thumb drive The USB port on the HK 3770s front panel lets you plug in your iPhone, iPod, or iPad to listen to music. This connection bypasses the devices digital-to-analog converters in favor of the receivers high-performance DACs. That means youll get smoother sound with more detail than your iPhone can deliver on its own. You can also use the receivers remote to control playback with connected Apple devices. The USB port is also great for playing digital music files on thumb drives by popping them into the USB port.
