Overview:

The AEQ OP-33H MPX channel has the same functions than the OP-33 module, but features a digital processing telephone hybrid equivalent to an AEQ EH02 ExMkII with one line. Thus, the telephone line will be connected directly to the module by way of the RJ-11 connector with no need to use additional equipment. Due to the hybrid’s digital processing, no adjustment is needed on installation

Module Features:
The telephone line and telephone set are connected by means of RJ-11 type connectors, which are located at the rear of the module.


There are two functions that distinguish the OP-33H MPX module from the OP-33 module, which are multiplex and frequency extender:

  • MULTIPLEX: When this key is enabled in a module configured in PHONE 1, the signal that is received from the telephone line is sent to the OP-33/OP-33H or OP-33H MPX module that is connected in PHONE 2. When this function is activated in both OP-33H MPX modules (if the console features two modules), both telephone lines intercommunicate.
  • FREQ. EXTENDER: When this key is enabled, the frequency extender function is activated. For a correct operation of this function, at the remote end has to be done the reverse procedure, by means of AEQ hybrids as the TH-02 EXMkII or TLE-02, or AEQ Audiocodecs as the TLE02D, MPAC02, SWING, EAGLE or COURSE.

This module has special features, which are programmed by means of the jumpers described below:

  • PDP1: Selects how the signal received at the hybrid is sent t the auxiliary bus.Put the jumper in position 1-2 to send the signal post-fader and 2-3 to send it pre-fader.This module is set in 'POST-FADER' by default
  • PDP2/PDP3: If you want to connect the module to the telephone bus PHONE 1 , both jumpers have to be put in position 1-2 nad to connect it to the telephone bus PHONE 2,both jumpers have to be put in 2-3 position.If you install a second telephone module,use the PHONE 2 bus and configure the PDPs in the other modules of the mixer.
Attention: NEVER CONNECT TWO TELEPHONE MODULES IN THE SAME 'PHONE' BUS
