Caution
!
To avoid potential damage, please ensure that the signal source is turned off before
connecting or disconnecting your active twotwo series loudspeakers.
Connections
The rear panel of the twotwo series monitor loudspeaker carries various connectors for
audio, control and mains power.
Audio
The electronically-balanced analogue input and the AES3 digital
input accept 3-pin male XLR connectors, wired with Pin-1 screen
(ground), Pin-2 signal positive (hot), and Pin-3 signal negative
(cold). An RCA-phono socket is provided to accept unbalanced
analogue signal source. The appropriate input is selected via the
rear panel menu system.
Power
The IEC (C14) mains socket is provided with adjacent power
switch. There is no AC voltage selector; the twotwo series monitor
!
can accept any AC mains voltage between 90-132 and 180-264V.
THIS UNIT MUST BE EARTHED
In – Thru Connections
The 'IN' RJ45 socket accepts volume data and digital audio from the previous twotwo
speaker in the chain (the first in the chain acts as the Master Volume controller). An
optional Remote Control unit can also be connected to the IN socket.
The 'THRU' socket sends the control signal to the next speaker, and also passes the
digital audio signal if the first speaker has a valid digital input from either its AES3 or
RJ45 'IN' connectors. Note: if the AES3 XLR and RJ45 'IN' are both receiving valid digital
audio, the XLR input automatically takes priority.
The twotwo badge on the front panel changes colour from white to red if the excursion
limiting protection system is activated. If this happens reduce the input level.
