PROS: Solid, well-built, durable Player/Recorder. Easy to learn menu function. Nice soft touch buttons.
CONS: No external audio output provided apart from the headphone plug-in connector.
Unit has no audio input adjustment!. The Audio record input reference meter level on the unit starts at -5 decibels!!! Hence audio input levels from the source has to be set at high levels to be able to register on the audio meters installed on the unit. Thus input audio levels below -5decibels wont register on the audio meters. And its difficult to monitor low audio input comfortably with headsets. Headsets has to be turned up at the almost maximum setting to be able to hear the input audio. This is a major design flaw which seem to be corrected in later models.
Not all 2.5" hard drives will work with the unit. You will have to check the listings.
The Datavideo HDR-45 would have been excellent IF audio input adjustment settings were provided and the audio meters on the unit were set at probably -40 decibels for monitoring.
