Overview of our technologies
The 150 Hertz mark is achieved through a 200 mm woofer with a 100 watt amplifier that delivers the hefty bass. Just what you need.
The IP 42 CR is an amplifier and compact AM/FM – receiver in one, with integreated CD drive and USB input. The high sensitivity tuner allows for 40 memory places.The active power amplifier with 80 Watts of power will fill your room with astounding levels of volume. A separate subwoofer connection completes the anticipated ensemble.
Along with the CD playback (Audio- and Data-CDs), the IP 42 can play USB memory stick audio files in MP3-format and can show their ID3-tags on the display. There are five additional inputs for devices such as TVs, MP3-players, iPod-docks, DVD-players, etc.Two of these inputs are on the front side for a quick and convenient connection. The full metal enclosure has many buttons with solid pressure points and a rotary knob.
The metal headphone jack guarantees durability and reliable contact. The ergonomic remote control that comfortably controls all functions is also included in this delivery.

An internal limiter protects it from overmodulation and distortion. The front control allows for the subwoofer to be turned on immediately, and the sensitivity of its standby mode can be regulated on its rear panel.
Four resonance-dampening feet ensure solid placement and isolate it from the floor. The US 5108/SW comes in black with a glossy black front plate and is only available as part of a set.

This circumstance would drive up the production and storage costs, which would result in a significantly more expensive sales price.
A paint shop in your vicinity will surely be able to repaint the speaker housing to your preferred colour without loss of warranty - after expiry of the eight-week right of return.
1. Remove the RCA cable from the input on the subwoofer. If the hum is no longer heard, go to point B. Otherwise, follow point A.
A. Attach the net cable of the subwoofer to another electricity outlet (i.e. Kitchen/Bathroom/Bedroom). If the subwoofer still hums, get in contact with our Support team.
Should the hum no longer be there, the disruption was a problem in your power supply, which can, for instance, be caused by dimmers or chargers. To find out where the disruption is, unplug all your devices and work back from there. As soon as the hum is heard, you now know your source of the disruption.
B. In your case, the "ground hum" is responsible for the disruption. Please proceed as follows to discover your source.
- Disconnect the cable or satellite port from the TV Receiver and check if the hum disappears or not. If it does, you can use a sheath current filter for the cable outlet to prevent this. For example, the sheath current filter AC 9022 ED. If you have a satellite connection, connect the Satellite Receiver to the optical cable playback source - Teufel Optical Digital Cable
- If this reason can be excluded, separate all devices from the AV Receiver one at a time until the hum stops. The last connected device is then your hum source and should be separated from the others using a galvanic separation filter (found in a retail shop)
- If this doesn't work, get in contact with us once again so that we can give an individual, helpful response.
Separate the direct connection by a grounding filter for the antennae cable that is created for it - for instance, the Teufel modell sheath current filter AC 9022 ED. Alternatively, you can use a galvanic separation filter that is looped into the connection between the subwoofer and AV Receiver.
The hum disappears if the antennae cable is separated from the Receiver/Tuner/TV. First try the grounding filter, otherwise the galvanic separation filter.
Placement within the straight line between both front satellites is ideal - but not precisely in the corner of the room because certain frequency components could be unpleasantly excessive when played back.
The membranes of the satellites should move to the front at the same time as the membrane of the subwoofer bass speaker, because all speakers of the system must vibrate in phase for optimal playback. This means that (provided the connection has the correct polarity) all drivers must move in one direction when the three front speakers receive a pulse (towards the outside or towards the inside).
If the subwoofer is in line with the front speakers, its bass speaker should have the same direction of movement (phase) - the controller on the woofer is set to "0". If the subwoofer is not between the front speakers, but is to the side of or even behind the listening location, its phase length will not match that of the front speakers. That is why the phase of the subwoofer must be changed in such cases.
So much for the theory. In practice, this means: Listen to a loud piece of music with heavy basses and ask a second person to change the phase during playback. The correct setting of the phase switch depends on where the subwoofer is positioned in the room. The position where the bass playback (above all the upper bass range) sounds the fullest is the correct position. Have fun trying it out!
This can be imagined as droning or booming, which occurs during heavy bass movie scenes such as explosions or certain types of music (Jazz, pizzicato bass). The bass absorber is then tuned exactly to this frequency so that only the speakers/subwoofer play back this frequency. The resonance frequency from the room, which would amplify this frequency, is swallowed by the bass absorber.
If you would like to damp more than one frequency (a room usually has three different frequencies: ceilings and floors, front and back and left and right, and its multiple), you will have to set up three absorbers accordingly.
The wattage (e.g. "360 W") printed on the rear of the subwoofer near the mains plug designates the ability of the power amplifier "to pull" a maximum power rating in the specified range at the moment of switching on (those 360 watt stated as an example).
Consequently, the wattage must correspond to at least the sine wave output of the amplifier, as this sine wave output must be permanently available which the power pack must provide as well.
The pulse/music performance of the amplifier, on the other hand, can exceed the wattage, because the short pulses are buffered additionally by the capacitors in the power pack and are not achieved solely through the performance of the power pack.
The wattage for a multi-channel subwoofer can also be below the sine wave output, as the specified sine wave output is not requested from every channel at the same time.
For a 5 x 100 watt sinus power amplifier, for example, each of the five channels is able to implement 100 watt sine. However, not all five channels at the same time! This is also unnecessary, as the same signal is never transmitted across all five channels at the same time, thus requesting the same high sine wave output per channel.
That is why the wattage may be, e.g. 300 watt, even if the sine wave output exhibits 5 x 100 watt (= 500 watt).
It is calculated of the sound velocity divided by 2 and divided by the room length [ 340 m/s: 2 : 6 m = 28.3 Hz (=1/s) ] or, more simply: 170 divided by the room dimension (length, width or height). The greatest distance between two parallel walls is taken as first standard value. For a room of 4 x 6 metres, this would be 6 metres. Strictly speaking, you would have to calculate the room resonance frequency for further parallel walls (for the 4 metres and for the ceiling height).
Overlaying resonances are also possible if the room dimensions are very close to each other. (2.8 metres high, 3 metres wide and 5.6 metres long). The resonance at 2.8 metres is repeated as multiple (times 2) at 5.6 metres length, the resonance of the 3 metres width is close to the resonance of 2.8 metres. It would resonate strongly here at 30 Hz, 56 Hz, 60 Hz and 120/112 Hz.
Phenomena of resonance frequencies:
• For example, a man with a deep voice speaks in a very small room (2 by 2 metres, 85 Hz). The voice appears to have more emphasis than in another room or out of doors. As soon as a woman speaks, the voice will sound just the same as in another room.
• The voice of a woman or that of a small child will cause glass to shatter. The voice strikes exactly the tone that corresponds to the resonant frequency of the glass. The glass resonates so strongly that it shatters (refer to the movie "The Tin Drum").
• A group of soldiers march across a bridge in cadence. The equal movement causes the bridge to vibrate so much that it collapses. That is why no one marches across bridges in cadence.
