Output power of sound car
What is REAL output power of sound cards like a AWE64, SoundBlaster. I heard about maximum 4W per channal. It is true? One of my sound card CrystalFusion is very quiet. In official specifications of products nowhere it is written.

Do you have a portable AM/FM radio sitting around in your house? What's the chance you would know the audio output in watts for such a device? In my case, right at or near, zero.
These things are known to put out little power. Most folks have a tuner in their stereo (as we used to call them) and use the portable radio only when it's practical to do so. Likewise, on our computers we connect the line-out to some amplification device and therefore generally have very little interest in the wattage of some internal chip or onboard device.
That said, if you Google it I wouldn't be surprised if someone hasn't archi'ved such information.
Good luck,
Richard

Can't find any info about iPod's (Nano and Touch) output power (in mW).
Please, help!I don't believe Apple makes that information available, but it is safe to say the output power is very low, probably around 30 to 100 mW at most. Just as important, the output is almost certainly optimized for headphones like Apple's own earbuds, so you won't get much power for loads much greater than 32 ohms nominal impedance.
Also, FWIW Apple hasn't been noted for providing a particularly high quality headphone amplifier signal path in older iPods but it may be paying more attention to this in newer designs. At one point, only the Shuffle featured a direct coupled output, which produced noticeably better bass response (cleaner, tighter sound, not just more bass), but now seems to be moving away from the inferior capacitively coupled output on at least some other models. -
where can I find the output power of my ipod nano 2nd generation? I've googled it but no luck... The apple site has lots of specifications about the iPods but no output power for the nanos (old or new)

i searched everywere and i didn't found the output power of the n96
i thing it's a big mistake don't apear in the specs. it's very important.
if some one could help me i appreciate.
something that for me would be better.. the sound should up and down 5 points when using the speaker(not 10)..like when we are using the headphones...
thanksWhen you say output power do you mean the how loud the headphones are, ie Volume?
Because the handset is of European design it has to conform with European Legislation, one country in Europe says that there is a maximum volume output a device can produce from its headphones.
You will find that most devices including European Models of the Apple iPod etc will also conform to this limitation. As Apple is a US company they make devices with and without the limit for EU and Non EU countries however as Nokia is based in the EU all their devices carry this restriction.
Shunts...
I will mostly be communicating with a Nokia E72 Zodium Black
Nokia E72-1 with Vr 051.018.207.04 Software

Adjust output power, Time Capsule
Hello!
I’m almost ready to purchase the Time capsule, but one question needs to be answered.
Earlier, it was possible to adjust the transmit power using the airport tool from a MAC and/or IOS.
To my knowledge, this function is not possible with the latest version of the Airport tool
I have also read somewhere that adjusting the output power IS possible with the Airport tool for Windows. Can someone please confirm that this is possible?
Adjusting the output power is a must for us.
Thanks and regards,
OleJust a (final) word:
This is what I sent to Apple:
Please add more options in the advanced setting in the airport utility, like the possibility to adjust the transmit power. Best to add separately adjustment for the 2,4GHz and the 5GHZ band since the later has less coverage and may need a higher transmit power settings.
From the former Airport utility user guide:
"Security for AirPort Networks in Businesses and Classrooms:
Businesses and schools need to restrict network communications to authorized users
and keep data safe from prying eyes. To meet this need, Apple wireless devices and
software provide a robust suite of security mechanisms. Use AirPort Utility to set up
these advanced security features.
Transmitter Power Control:
Because radio waves travel in all directions, they can extend outside the confines of a
specific building. The Transmit Power setting in AirPort Utility lets you adjust the
transmission range of your device’s network. Only users within the network vicinity
have access to the network".
I think that Apple don't care much about security when they now has removed the possibility to adjust the transmitter power as well as other advanced settings.
And yes, I have no illusion that they will listen to me...

Anyone get to know what's the output power of the audio system?
Hi. It's there anyone could tell me what's the output power of the 2.1 audio system in this 24" LED display?? Thanks
Gabi759,
The output on the Audigy 2 ZS is Line Level. We no longer use amplification on the card as that can cause distortion and an overall loss of audio quality. You may want to look at either replacing your speakers (as few sound cards have amplification) or get a preamp for them to power them.

MuVo2 (1,5G): Can I Use output power only (not install the battery) when I listen the mus
Hi Sir:
When I am in home and listen the music on MuVo2 ,can I use output power only (AC power) and remove the battery ( the battery is not in the MuVo2)?
This is good to the MuVo2 or not ? (have any damange?)
Because I always use the MuVo2 in my home, I think to charge AC into the battery, and use it until in low battery , then charge again.. It seem to a little stupid....
Can I use AC(output power) only when I listen the music ? and remove the AC(output power) when I close/shut down the MuVo2 ? ( I know , the usermanual say it is not good to MuVo2 if AC(output power) "always on" the MuVo2 even it's shutdown.)
I saw in the usermanual there will be a little image indicate the MuVo2 is "output power only".... So can I use output power only or not ? Is it good to MuVo2?
Thanks a lot !!
( Your product is great~!)
B/R, RichardRichard,
Yes, you can use the player on the AC outlet only if you want, that's fine.

How to reduce Hub 3 output POWER?
I use my laptop in the same room (~5m) as the router and wondered if there was a way of reducing the output power from the Hub 3 antenna, which has a range of ~40m? I have two young children in the room and am concerned about wi-fi signal levels. A colleague mentioned that he can reduce the output power of his APPLE router easily. Is there a similar option for the Hub 3 BT product? I realise that if I do not have the laptop switched on, i.e. no activity, then the power level drops automatically, which is a great feature. Thanks, Fred.

There is no facility to reduce power apart from the power save option which turns the WiFi off.
The maximum power allowed by WiFi is 100mW (100 milliwatts) which is very small. If you are concerned about WiFi, then it would be better to turn it off, and connect to your laptop using an Ethernet cable.
You can extend the Ethernet port of the hub by using Powerline adapters. Which use the mains wiring to carry the data.

WAP321-E-K9/max RF output power of 802.11a?
Does the WAP 321-E-K9 (as 5GHZ frequency) supports the 802.11a?
If yes, please specify exactly the output power transmission in dBm?
Is it possible to have the 5GHZ frequency that not support the 802.11a? Because in the technical sheet of the WAP 321-E-K9 there is no specifications about the output power transmission (dBm) of the 802.11a standards ( only 802.11b/n/g are specified) ?Hi commercial7,
I hope this helps:
From the product documentation on the WAP321-E-K9 it appears that the WAP only supports 802.11b/g/n protocols. 802.11a (5GHz) is a legacy protocol that was outdated with the release of 802.11n (2.4/5GHz). While WAPs that use 802.11n are backwards compatible (support 802.11a/b/g devices), WAPs that use 802.11a won't support devices that use newer protocols.
According to the WAP321 Wireless-N documentation, transmitted output power: 802.11n @ HT20HT40, MCS15: 13 dBm
Also according to the WAP321 Wireless-N documentation, receiver sensitivity: 802.11n: 300 Mbps @ -64 dBm. Since 802.11n should support 802.11a, you may want to check the hardware specifics for the 802.11a device you are trying to connect with.

Mention in Spec.:Radio output power: 32.5 dBm maximum (varies by country) .
Any list of country+model for output power? Which model of ATC-2TB has Max. Power?Hi,
This is Marcus from Application Engineering at National Instruments. I have reviewed over your math and you are correct in your calculations. To determine the power output of your PXI-5422 you will have to know the Vpp which you are using and also the load that you will be connecting to the device. These factors will then determine the power output of your PXI-5422.

Just a quick question. Today was migrated to 21CN. When I was on the old 8Mb service I notice3d that the output power on the HH was usually between 16dBm and 17dBm, but since the migration to 21CN I notice that the output power is 0.0dBm, this is on the down, but on the up it is the same as before. I have tried different HH's and still the same result. What should the output power be?
