ULTRA-DI DI20
1. Welcome to the Behringer Family!
On stage as well as in studios, it is sometimes advantageous to
connect certain sound sources directly to the mixing console.
Sincemany instruments (keyboards, forexample) don’thave balanced
outputs they require a DI-box. Sometimes, evenguitars can’t be
directly connected to mixing consoles because their impedance is
too high.
By using a DI-box, you can directly tap into a high-impedance,
unbalanced signal—forexample, a signal between a guitar and a
guitar amplier. From this point, you can feed this signal directly to
a mixing console.
There are active and passive DI-boxes. A passive DI-box is more
aordable, but its performance is dependent on the impedance of the
device to which it is connected. When the impedance on the mixing
console’s end changes, so does the impedance at the input of the
DI-box. Such DI-boxes only function properly when the connected
impedance values are strictly specied (high at the input, low at
the output). Active DI-boxes are not aected by these impedance
considerations. The input impedance of the DI20 is extremely high,
and it absolutely does not inuence the signal ow through the
DI-box. The output impedance is balanced and always very low,
whereby the signal is far less prone to being aected by noise.
◊ ◊ To prevent damaging your loudspeakers, rst connect
the DI-box and then hook up the respective channel.
The same goes for alternating between battery and
phantom power operating modes.
