Hi all… I was looking at a photo of the back of a NAT 01 & NAPST and I’m sure I’ve connected mine wrong (although I’m getting a signal to the preamp)…
Mine’s connected like this at the moment:
But, looking at the legends on the back, I think it should be connected like this:
Have I got that right..? Also, the way I’ve got it connected, the audio signal isn’t being routed through the NAPST, is it..?
TIA
The NAPST was changed, mine is the first iteration with the FM / AM / AUX selector on the front. Different socket layout…
It’s an early one, so different layout. Looks ok to me but can check in my old manual when I’m home.
The latter is how mine is connected.
@marksnaim Thanks, I suspected as much… odd that it still works the way that I have it connected. I’ve always wondered about Naim’s insistence that the audio signal be routed through the power supply…
It’ll still work fine, in that you’ll get audio out on the DIN4 socket on the head unit using a DIN4-5 interconnect.
I presume (if the AM head had ever been produced) the multi head PST Tuner selector dial was designed to switch power to the appropriate DIN7 output. It would also route the audio signal coming back from the DIN4 on the powered head unit to the DIN5 output on the PST, connecting to the preamp via a standard DIN5 interconnect.
@james_n Thanks. By the way, I heard that the ‘AUX’ selector was for a putative TV tuner…
Interesting. IIRC back in the day, Arcam produced a NICAM tuner for TV audio. I wonder if Naim were thinking of doing the same ?
I think the TV tuner idea pre-dated NICAM. The AM tuner was doubtless too late in the day, even with the promise of AM Stereo in the States, which didn’t really take off in any big way.
I remember having a demo of the Arcam Nicam tuner. I recall that I was quite impressed, but not enough to actually go out and buy one. Interesting to think that at the time Arcam had quite a system to offer in their Delta range, entailing not just a great CD source, but a separate DAC, great tuner, pre-power amp (and a couple of integrated amp options), a Nicam tuner, a top class cassette deck, and speakers. I still regularly use a Delta 80 tuner, and Delta 90 and Delta 60 amps and they have been super-reliable.
Thanks Richard - Interesting info.
Interesting. I wonder if the more direct route actually sounds better? I don’t use the NAT01 very often for critical listening, more as background with R3, but I might experiment because it’s a simpler arrangement.
Worth trying, Mark if you have a spare DIN 4-5 cable. You’re eliminating a number of unnecessary items in the audio signal path - cable, connectors and selector switch.
Naim did that themselves with the later NAT01 with the single output NAPST. The audio output is straight from a DIN5 on the head unit (as shown in RWCs post).
