5.1 surround sound playback system
In order for you to benefit fully from the intended surrounding effect of the 5 100, it is advisable that you are familiar with the 5. 1 surround
playback setup.
"5" refers to the number of full range discrete channels, ". 1 " refers to the frequency limited range of the LFE (Low Frequency Effects) channel.
• Two full frequency range channels for speakers at the front: Left (L) and Right (R).
• One full frequency range channel for speaker between left and right: Center (C).
• Two full frequency range channels for surround speakers at the rear: Left Surround (LS) and Right Surround (RS).
• One Low Frequency Effects channel (LFE).
5. 1 surround (also known as 3-2 Stereo: three front speakers and two rear speakers) delivers five discrete audio channels and 1 LFE chan-
nel from a six-channel source. Source media, usually DVD and satellite/digital cable, is often branded with "Dolby Digital" and/or DTS logos.
Publically available digital discrete coding formats are Dolby Digital 5. 1 , Dolby AC-3, and DTS (Digital Theater System).
Placement: 5.1 speaker layouts should conform to the ITU-R BS.775 standard:
The ITU (International Telecommunication Union) standard states that the left and right speakers
are located at ±30˚, while the rear speakers should be positioned approximately ±1 10˚ off center axis.
• Three identical front speakers.
• Equal arrival time (radius) between mix position and each speaker.
• If placed behind a silver screen, the screen should be acoustically transparent.
• Surround speakers placed within 100˚ and 1 20˚.
If more than two surround speakers, symmetrically placed on radius between 60˚ and 1 50˚.
• LFE runs to separate subwoofer or equally to left/right, and is played back at +10 dB level.
Mounting the microphone
The 5 100 has a standard 3/8" microphone stand thread above and below the unit.
Any third part mounting accessory having 3/8" thread can be mounted
– microphone stand, hand grip or the like. Remove the inner thread a
the bottom to acces American 5/8" thread.

Connecting and disconnecting the cable
The 5. 1 output of the 5 100 runs through a multi-pin Lemo connector carrying all six channels electronically balanced. The enclosed DAO5 105 5
m (1 6 ft) six-pair Mogami cable breaks out to six Neutrik XLR-M connectors. Other cable lengths are available as optional accessories.
Note
To align the two red marks, gently push the connector into the terminal beneath the 5 100 until it locks with a click.
Disconnect the cable by drawing it away from the 5 100 at the cylinder. This will unlock the connector.

48V Phantom power should be applied to all six cables. Note, the LFE output is only active when phantom power is applied to Left and Right.
Application notes
The DPA 5 100 can be used handheld, mounted on a camera, on a microphone stand
or suspended. Further shock absorption is not necessary.
DPA OC5100 Outdoor Cover
When using the 5 100 outdoors, always mount the DPA OC5 100 Outdoor Cover,
which both protects the unit against rain and reduces wind noise.
Extension units
When mounted on a handheld camera, it may be necessary to
increase the distance between the microphone and any noise
sources such as camera zoom and breathing.
