SPEAKER CONNECTION
The TXM16 and TXM20’s power amplifier section can be
configured to operate several ways depending on the set-
ting of the power amp MODE switch located on the front
panel. This allows you to choose whether you need MAIN
plus MONITOR amplifiers to power your speakers, or if you
just need more power for the MAIN speakers. For more
information on the POWER AMP MODE switch, see the sec-
tion POWER AMP SECTION on page 12 of this manual.
There are three ways in which speakers can be connected
to the TXM16 and TXM20: A single speaker can be con-
nected to either the 1/4-inch jack or a Speakon connector
of AMP 1 and AMP 2, two speakers can be connected in
parallel to both the 1/4-inch jack and a Speakon connec-
tor of AMP1 and AMP 2, or a single speaker can be con-
nected to the BRIDGE jack (bridge connection). For each
of these, the required speaker impedance will differ.
Refer to the following diagrams, and make sure that the
speaker impedance is not less than the specified value.
Additional, or alternative amplifiers and speakers, or pow-
ered speakers can be connected to the MAIN MIX OUT , MAIN
MIX OUT2, AUX 1, AUX 2 SEND jacks on the top panel.
TXM16 and TXM20 Input and Output Connections
When connecting one speaker to POWER AMP 1 and one
speaker to POWER AMP 2, use speakers with a 4 – 8 ohm
impedance rating.
When connecting two speakers to POWER AMP 1 and two
speaker to POWER AMP 2, use speakers with a 8 – 16 ohm
impedance rating.
When the POWER AMPS are in BRIDGE MODE, use speak-
ers with an 8 – 16 ohm impedance rating.
