There is an adjustment on the back middle. If it is connected to a audio source, the red light should light up on the front.
Then there is an adjusting dial next to the volume turn that until you get the sound you want.

Good luck

    It appears that your Wii console's Internet connection may be affected by wireless interference. Try the following:
    • Change your wireless router's channel to 1 or 11
      Changing the wireless channel on your router may help. Most wireless routers have a channel range of 1 through 11. The best channels to try are usually 1 and 11, as they do not overlap with other channels. Typically, the channel settings for your router will be found in the router's main "Wireless" tab.
    • Where is your wireless router located?
      Move your router away from walls and off the floor and try to place it in a central location in your home. Also, keep it away from metal objects such as metal filing cabinets which can cause interference.
    • Look for other devices
      Noise from cordless devices (cordless phones), or wireless electronics (wireless keyboards, headphones, cell phones), especially those using the 2.4GHz frequency, can interfere with your wireless signal. Also, older microwave models can cause wireless interference. Avoid electronics that use the 2.4GHz frequency, instead look for devices that use the 5.8GHz or 900MHz frequencies.

Need earpad replacements for Optimus Pro-100 Wireless headphones


Just flip the headphone pad inside out on the Optimus Pro 100 wireless headphones.
Find the 3 screws on each headphone speaker, you have to push the existing cover back, but you'll find them. Remove the 3 screws. Be careful of the speaker wire that will be attached to the cover plate that has the ear pad on it. Also, look carefully at how the components are assembled inside the headphone, as you might disturb their setting. They are easy to return to their proper place if they move.
Gently remove the ear pad, turn it inside out and you will have a new covered ear pad. GENTLY, re-install ear pad onto speaker plate, be careful not to break the speaker wire that is attached. I found a little flat screwdriver helps to pull the edge of the pad over the plate. The ear pad is actually quite strong and can take some abuse, but don't pull the speaker wires loose.
After you have the cover back on, find the screw holes and put the 3 screws back in. Presto, a little cleanup on any loose pieces of covering from the original side and your done for another couple years or so.

Wifi interference??


The short answer is that it could interfere with the wi-fi, but your wi-fi should not interfere with your phone because it uses WDECT, "wide-band digitally enhanced cordless telecommunications" engineering. No matter how tight the bandwidth is on any RF transmission, power, proximity, and harmonics all play a roll. Ideally we want the power from our transmission to occupy the target frequency but the reality in RF is that this is nearly impossible without DSP filters. I have pasted some extra info below to help answer this question.

Digital Enhanced Cordless Telecommunications
(DECT), known as Digital European Cordless Telephone[1] until 1995, is an ETSI standard for digital portable phones (cordless home telephones), commonly used for domestic or corporate purposes. It is recognised by the ITU as fulfilling the IMT-2000 requirements and thus qualifies as a 3G system.


The four most common frequencies today are 900MHz, 2.4GHz, 5.8GHz and DECT 6.0:

900 MHz Currentlythe most common frequency for cordless phones, 900MHz phones may offera greater range than other frequencies. However, the 900MHz spectrum iscluttered and may result in interference with baby monitors and other900MHz cordless phones. Radio scanners can also easily pick up thisband. 2.4 GHz 2.4GHzphones offer better clarity and security than 900MHz, but mayexperience some interference with microwave ovens and wirelessnetworking (wi-fi) products. 5.8 GHz Themost advanced cordless phones available, 5.8GHz phones transmit on anew, open frequency and have the least chance for interference. Theywill not interfere with wireless networking (wi-fi) products. DECT 6.0 DECT6.0 operates on the 1.9GHz frequency. Though newly approved in the US,this frequency has been used for many years in Europe and can increasecall clarity and security. The wi-fi friendly DECT technology easilyintegrates into homes with wi-fi and internet services because the1.9GHz frequency is exclusive to DECT, making it interference free forcordless communications.

Frequencies


Hello again ronnieyannon,

It's probably best to allow the amp that is powering the subs to control the frequencies going to the sub(s). I would not use the lpf on both the head unit and the amp in any case. The control settings are not completely precise and you could end up with a lot of tweaking between the units to get the sound you want. I'd send full range to the amp and with it playing something with a lot of bass, set the 401s to "LP", the crossover slope to near maximum, and then adjust the frequency until it sounded best to me. Starting on page 11 of your manual are the Rockford-Fosgate recommended adjustment procedures, including setting the gains and the filter frequency.

Those numbers for the lpf on your head unit sounds like it allows you to decrease (-24dB), as well as increase (+6dB) the bass at the specific frequencies of 50, 63, 80 and 100Hz. You probably don't want to decrease the bass boost for subs. And the 401s will allow a boost up to 12dB and is variable from 50-250Hz.

Hope this helps.

Frequency clash


There are different frequencies available and being used in each location.

To get a basic idea of which frequencies are available in your area, try this online tool:
http://www.sennheiserusa.com/findfrequency/
or use the literature provided with the Sennheiser gear (usually a useful chart comes with the wireless gear).

Also, remember that your transmitting frequencies need to be spaced apart a minimum of .400 MHz (or 400 kHz).

Frequency selection shouldn't cause feedback problems though. If you select a frequency for a mic that a local TV station is already using to broadcast, it will cause RF Interference (Radio Frequency). You'll probably hear static noises, pops, or since your Sennheiser has a Squelch feature, just drop-outs in audio.

So first consult the available charts to find a set of frequencies that should be available in your area. Then, if one of your mics is experiencing such an issue, try moving it .400 MHz to the nearest unused frequency and see if the RFI goes away. Repeat until the RFI no longer manifests.
