Digital Aux Input

Zoltan · 09-03-2004, 01:47 AM

Thought I'd ask an old question again...

Are there any Head Units with an Optical or Coaxial SPDIF input?

Likewise, other than the TDK 6ch amp, has any one seen or used an amp with digital input? How bout for a reasonable price?

Probably nothing except extremely high end headunits. Even my high end Eclipse only has a Coax SPDIF out for use with a DSP.

Have not seen HU with digital in

amps as follow
prototype) Pulsus Tech 6ch Digital Amp (SPDIF input or I2S)
Alpine V12-Accuclass D MRA-D550 5 channel. 2 optical in.
Pioneer RS-A9 4 channel
Pioneer RS A7 4 channel

more to follow.
price unknown
ps. some of the sony's high end system use optical to transmit. not sure if they will work with other brand's head unit or carputer

Also Phoenix Gold has the OCTANE-R 5.1MT.
It can be had for about $400 with shipping at the few places I have seen it listed. List is $450.

Looks pretty sweet. If anyone has one of these, write us a review!

Thanks.

Is that thing out yet? I remember talking to one of our reps almost a year ago about that amp... I wanted it and was told it would be out soon... of course, to this day, I haven't seen any info on it other than the stuff he showed me. I guess I could call my supplier but its not even on Alpine's website. Soooo... you have any info? Thanks!

My Eclipse CD8454 has a Coaxial SPDIF Input for stereo PCM data.

I run my carputer into it.

So is your Coaxial SPDIF Input on your head unit selectable as an AUX, and does it use the HU's internal amp? If so, that is so cool. But, I don't think I'll have room or the desire to have a HU.

I'm calling PG tomorrow about that amp though. I'm kinda bummed that I can't find a single review of it online.

I think the Phoenix gold is the only one out I can't find the alpine or pioneer amps with digital inputs anywhere and I have been looking.

Old School Sony Moble ES cdx-90, and cdx-910, both can do it with a optional digital connection add-on, I'm currently using a Panasonic cy-ac300, hidaway unit, No HU, running digital to my Sonica sound card, Amazing sound,

I have the Phoenix Gold 5.1MT. It's works good, I love the optical input, no noise, etc.

The downsides I haven't been able to make the sub woofer output work. The line level pre-outs for a secondary sub woofer amp are well below what they should we, 3 Volts, so I haven't been able to another amp either. I guess I'll have to send mine back eventually but would likely lose all audio in my car for a few weeks while it's being fixed.

Isn't the 100Watt Sub Channle enough

The only issue I have with the PhoenixGold is the rated Power is at 14.4V (something no one can get) the real power output is 18x5 and 37x1 which is way low for a car system I think..

I was going to get a DEQ with Optical inputs and plug the carpc into that.

My sub channel doesn't work either.

But I would doubt that it would be very powerful given the size of the amp. I don't think it’s not sable below 2 ohms. It's not as big as I was expecting and it only weights about 5 pounds. I was expecting something more heavy. It drives the main channels just fine.

the denford unit (rockford fosgate 8250 built by denon) has digital inputs
