Item #: SCP-XXXX
Object Class: Safe
A picture of SCP-XXXX by the original owner prior to containment.
Special Containment Procedures: SCP-XXXX is to be kept in standard object locker-room 4a in site 15 inside of two Faraday cages: one lining the room and the other directly outside of the table holding SCP-XXXX—all of the said Faraday cages must be independent of the electrical isolation of the site’s containment wing to prevent grounding failures. With this, there are to be four low-gain radio antennas positioned outside of the room and two high-gain antennas inside of the room outside of the Faraday cages. If any radio signals are detected through the high-gain antennas, MTF Mu-4 (“Debuggers”) are to be called in to add extra layers to the Faraday cage system and destroy or stop the broadcast source of said signal. The Faraday cages are to be made of layers of sheet metal in order to block the most electromagnetic radiation possible.
However, the object is also to be kept unplugged and turned off. The object has no potentially dangerous properties unless it is powered on.
Description: SCP-XXXX is an anomalous audio-amplifier capable of changing its specific make and model on a bi-monthly basis.
SCP-XXXX has also been observed to pick up radio signals from nearly any source when no audio sources (i.e. record player, cassette deck, MP3 player) are directly plugged in to the object. When it picks up a simple waveform such as a sine or sawtooth wave, it has been observed to play it back across speakers in a nearby area of at least 10m (provided no impedance to signal flow in this radius) at approximately ten times the waveform’s original amplitude.1
Upon further inspection and testing, when plugged in to a wired audio source such as a guitar, synthesizer, or electronic drum set. SCP-6098 has been observed to be able to play the audio back at an extremely high volume when also plugged into a wired audio output. The highest recorded volume was 320dB—the same volume as the Saturn V rocket at liftoff. Tests show that even with the massive volume coming from the object, no speaker blow-outs have been detected. See Experiment Log XXXX-1 for more details.
Despite several diagnostic checks, no components in the internal circuits of SCP-XXXX have been observed to have any abnormal properties. Including the transformer, which seems to always have an abnormally low voltage-drop across its secondary coil. Further diagnostic checks are under way to see if an antenna is somehow present within the device in any of its forms.2

{{BEGIN LOG
LOCATION: SITE 15, SONIC-TESTING ROOM, RM-#94B
SUBJECT: DR. GERALDS}}
Dr. Geralds is affixing a turntable and a set of 1970s-1980s ‘hi-fi’ audio speakers to SCP-XXXX.
Dr. Geralds: Alright, let’s see how high we can get this to go.
Dr. Geralds places the needle down on the turntable. The record starts to play.
Dr. Geralds: If this thing wasn’t anomalous, I would keep it for myself.
Dr. Geralds then turns the volume on the amplifier to the highest normal levels. He can be seen covering his ears with his hands.
Dr. Geralds: I guess now is the time to put on my hearing protection.
Dr. Geralds proceeds to put on his hearing protection. He then turns the volume on the amplifier up more. At this point the volume of the music is approximately 12dB
Dr. Geralds: Screw it! I’m not going to do this whole thing myself!
Dr. Geralds then brings in the assistance of a XRB-1A lab robot in order to turn the volume knob for him in order for Geralds to preserve his hearing.
Dr. Geralds: Just turn the volume knob for a while once I get out of the room.
XRB-1A: Yes, Dr. Geralds.
Dr. Geralds then enters the control room to monitor the volume output.
XRB-1A proceeds to turn the volume up to approximately 100dB. It can be seen that the volume knob has been rotated around 1.5 times.
Dr. Geralds (to XRB-1A through the remote command system): Go a little quicker, would you?
XRB-1A then turns the volume knob approximately 2.9 times. He can not turn the knob any more. The measured volume is at 320dB—the same volume as a Saturn V rocket.
END LOG
After the test, it has been shown that XRB-1A has acquired major damage to its internal microphone circuits. Technicians should be able to repair it easily.
However, it has also been shown that the speakers used for SCP-XXXX have not taken any damge, and work perfectly fine. Further research is needed to see whether this is just the speakers or a property of the object.
