Using The Direct In Connector; Of 3.4 Mono Mode; Mute Function (Ha4700 Only); Connecting Multiple Headphones - Behringer POWERPLAY PRO-XL HA4700 User Manual

POWERPLAY PRO-XL HA4700/PRO-8 HA8000
This way, you can for example effortlessly record vocals and
feed in an already existing playback using your POWERPLAY
PRO-XL HA4700. The playback signal is fed through the MAIN IN
inputs, and the preamplified vocal signal is fed into the AUX IN
connector. The respective BALANCE control should be set up in
such a way that the singer gets a perfectly matched mix between
the playback and the vocals, whereby the OUTPUT LEVEL control
regulates the overall volume.

In addition to the usage of all channels via the MAIN input,
each of the four amplifiers can also be used fully independently.
To this end, you may also use the AUX IN inputs in conjunction
with the BALANCE controls. When the BALANCE control is turned
to the left (“AUX” position), the MAIN signal is faded out, and the
AUX IN signals are fed into their respective amplifiers. Using
individual amplifiers separately lets you provide individual mixes
to up to four musicians.

3.3 Using the DIRECT IN connector

The DIRECT IN connector (HA4700) is located on the left side of
the front section. For example, you can use this connector to provide
musicians with the signal of a DAT recorder or CD player. The
HA8000 has a separate DIRECT IN connector for each amplifier
(located on the rear). In the case of the HA8000, allocating a signal
to this connector mutes the MAIN IN signal. The input level must
be externally set in this case. This way, you can use each amplifier
section for a separate headphone signal.
3.4 Mono mode
Stereo signals can often have an irritating effect in certain
monitoring applications, especially when performing live. These
negative effects are particularly apparent when both channels
show great channel separation, i.e. a different information content
coupled with varying volume levels. The ST./2-CH. switch
(HA8000: the MONO switch) allows coupling the left and the right
channels into a single mono signal, withouth needing a
“Y”-adapter or a special cable.

3.5 MUTE function (HA4700 only)

When the ST./2-CH. switch is depressed, the unit is running mono.
By depressing either one of the MUTE switches, the respective input’s
signal (i.e. either the left or the right input) is muted, while the signal
not being muted can be heard on BOTH (left and right) headphone
outputs. This allows you to feed two different program sources yet
be able to listen to only one of them on a per-need basis.

while the HA8000 has two. You can connect multiple headphones
to an amp simultaneously, provided that the minimal output load
impedance of the amp does not fall below 8 Ohms. In the case of
the HA8000, the minimal output load impedance is 100 Ohms per
amp.
