Binding Post Outputs - QSC Audio RMX 4050HD Manual Del Usario

XLR and TRS (1/4") INPUTS
Each channel has a balanced 3-terminal XLR and TRS input.
Inputs are connected with standard cables and can be
changed quickly. Pinouts are marked on the rear panel and
shown in the illustration.
The input impedance is 20k ohm balanced or 10k ohm unbal-
anced.
Balanced connections are recommended to reduce AC hum
and interference, especially with long cable runs. Unbalanced
connections may be suitable for short cables. The signal's
EN
source impedance should be less than 600 ohms.
Unbalanced TRS connectors (2-terminal) automatically con-
nect the minus (-) terminal to ground when inserted.
OUTPUTS
Wiring connections are shown on the back of the chassis.

BINDING POST OUTPUTS

Stereo and Parallel Mode: Wire as shown by loudspeaker sym-
bols 1 and 2.
Bridge Mode: Wire as shown by Bridge Mono loudspeaker
symbol.
SPEAKON OUPTPUTS
Each channel accepts a normal 2-wire cable. In addition, Chan-
nel 1 accepts 4-wire cables for single cable stereo or bi-amp
connection.
OUTPUT TERMINAL SAFETY WARNING! Do not
touch output terminals while amplifier power is on.
Make all connections with amplifier turned off. Risk
of hazardous energy!
Stereo and Parallel Mode- Connect each loudspeaker to its
own channel of the amplifier, as shown on the left side of the
chassis label. The Mode configuration switches must be set
for Stereo or Parallel Mode.
Bridge Mode- Bridge Mode configures the channel pair to
drive a single audio circuit. The Mode configuration switches
must be set for Bridge Mode.
Connect the load as shown on the right side of the binding
posts or to the left on Channel 1's Speakon. 4 ohms is the min-
imum impedance for Bridge Mode use.
Do not use less than 4 ohm load in Bridge Mode!
Note polarity of connection for Bridge Mode.
OUTPUT WIRING WARNING:
CLASS 2 WIRING SHALL BE USED.
FOR BRIDGED MONO MODE, CLASS 3 WIRING
SHALL BE USED.
