Was wondering if the new Squeezebox Radio can be connected to an external amp such as the Sonic Impact T-amp via the headphone out mini jack?

You could, especially because the headphone jack is stereo (unlike the Radio's built-in speaker, which is mono). For best audio quality it's generally better to use a line level output into an external amp instead of a headphone jack, so that's a compromise you'd have to make. Personally I could see doing that as an occasional thing, but if you want something to be connected to the T-amp most of the time I would go for any of the SB players *except* the Boom and the Radio.

Generally speaking, using a headphone out to drive a line-input will not cause even the slightest degradation in audio. However, if your line-input does not have proper anti-aliasing filters, it could cause an increased noise floor. Typically, this is not much of a problem.

Ironically, high-end equipment could suffer more than low-end equipment in this regard because sometimes high-end designers make the mistake of attempting to preserve perfect frequency response to 40kHz or even farther, which only lets more noise into the system without actually improving anything sonically.

I use the headphone jack to connect to a spare Bose radio for occasional outdoor use. Works fine, though sound level is a bit low. Plus the headphone jack doesn't allow for use with Slacker or Rhapsody (under 7.3). For regular use I would also recommend another SB product.

Good to know. I would be using the Squeezebox Radio and external T-amp in the Master Bath (primarily listening to music while in the shower) through a single ceiling mounted dual voice coil speaker. And it appears that for this purpose and in this less than ideal or critical listening environment (lots of noise reflective surfaces) that the Squeezebox Radio might be perfect. Thanks for the insight.

I stand corrected on the question of audio quality. Caleb certainly knows more about it than I do! I have seen a lot of postings (which corresponded to my own experience) about using the SB2 or SB3 RCA outputs instead of the headphone jack for driving self-powered speakers, and I assumed the same applied to running it to an amp, but perhaps that advice was wrong, too. Anyway, you won't notice the difference in an acoustic environment like a bathroom.

Re jbart1965's comment about Rhapsody and Slacker, it sounds as if he is referring to using an SB Controller. The SB Radio doesn't have those limitations on getting music services.

SB2 and SB3 RCA connectors actually use a different amplifier from the headphone jack, and they are superior to the HP for line-level applications.

But, that's not a general rule, just specific to the SB2 and SB3 design.

I have a squeezebox radio that I use to run my "whole house" sound system. I use the headphone jack output, and then an adapter to convert stereo to mono (because I only have a single speaker in each room) and then that signal gets split. One side of the split is plugged into a small digital amp that powers a speaker in my bedroom and one in my bathroom, and then the other side of the split cable goes into a wireless transmitter (that and the prementioned amp are inside my nightstand) that sends the sound to a wireless receiver/amp in my kitchen pantry that powers a speaker in my kitchen and one in the room with my pool table. All of this is controller using the iPhone app iPeng. It is such a great setup. I just did it all about a month ago and couldn't be more pleased. See attached pictures. If you have any questions on exactly what products I used or about the installation feel free to ask. The sound quality is actually very nice, and it was pretty cheap. The speakers were $70/pair, the amp powering 2 of them was $50, and the wireless transmitter and wireless receiver/amp were about $150 for the set.

I recently got a Squeezebox Radio and have tried connecting it via the headphone jack to my surround sound receiver. The headphone jack analog signal is considerably lower in volume (even at max volume) when A/B comparing to a digital signal from my WDTV (playing the same music file).

Aside from that, it does work but is not ideal.

Hi PWB,

I saw your setup here.
Can you tell me which components you used?

I wanna make a simular configuration. So I if you can help, i would be very happy.

Hi ccrome2,

Could you please tell me what is considered "proper" anti-aliasing filters? I am thinking to get a Harman Kandon stereo receiver (DH-3390) for squeezebox radio, hoping it may improve my music experience with Squeezebox. Now I am using my consumer-grade Philips home theater receiver with Polk Monitor50 speakers. Do you think the 3390 has a proper filter? It would be too costly to get another squeezebox receiver, or even a HK 3490, which has digital inputs. What if the result is even worse than the low-end receiver?

Here is the manual of 3390 with specshttp://www.esotericsound.com/Electronics/HK_3390_OWNERS_MANUAL.pdf Some people complain the device let any bass signal input so it may sound boomy in some HK home theater receivers . How about the stereo 3390 with separate subwoofer outputs? Is it a good match for SB radio via headphone-RCA cable?

People can't get why someone like me wants to connect SB radio with audio system. BECAUSE it is cool and less expensive to have a versatile device that can do both. The radio is versatile -- now I hope I can find components that make the headphone output work as well as audio output.

I m the happy owner of a Squeezebox Radio . I d like to buy a Sony HTCT370 Soundbar with Wireless Subwoofer.

I d like to connect the Squeezebox Radio to the toolbar using a cable. As you know The Radio has an headphone jack and Sony Soundbar has a hdmi IN !

Is there a cable i can use with which connect my Radio to that Soundbar ?


Thanks for your Help

Unfortunately not. HDMI is a digital standard, so you would need a bunch of complicated electronics, including an analog-to-digital converter. The soundbar also has an optical audio input, but the Radio doesn't have a digital output.

A poor option would be to use a Bluetooth audio transmitter adapter on headphone socket and send audio to soundbar using Bluetooth.

Otherwise - buy a Touch with optical output or build a small player and control the player from the Radio.

Thanks for all your replies

i have read soundbar has also an analog in .... does it change anything ?

Yes, it does. You should be able to plug in the headphone output of the radio into the analog input, all you need is a standard 3.5mm jack cable.
