Marantz AV7705 AV Receiver: HDMI out to external DAC
I’d like to bypass this receiver’s DAC & preamp and send its digital-audio output to an external DAC via HDMI (a T+A R 2500 R integrated amp). Unfortunately, doing so results in no sound.
I was told by Marantz support that this unit can't output analog & digital signals at the same time. However, none of the AV7705's analog outputs are connected.
I realize that I could always send analog FL & FR signals to the T+A, but then I’d lose the LFE channel & couldn’t take advantage of the T+A’s high-end DAC & preamp. The T+A hosts other sources (phono, disc player, etc.), so it’s hardwired to my powered sub.
Marantz support doesn’t know the answer to this question (!) and my manual doesn’t document the receiver’s HDMI output in much detail. Does anybody know if the AV7705’s "Monitor 2" and "Zone 2" HDMI outputs actually transmit digital audio that can be decoded by an external DAC?
Well, the Marantz is a $2400 A/V prepro and the T+A is an $19k stereo integrated amp so kinda apples and oranges here — on many levels. |
@blisshifi can obviously tell you more, but it’s unlikely the HDMI output from a mass market AVP is compatible with the HDMI input on the 2500 as the Marantz probably only outputs Dolby/DTS signals the 2500 likely won’t process and is why you’re not hearing anything. That’s my guess anyway. |
