Electronic Equipment

The connection of AEV ITB-302 to 2-wire telephone lines is made by inserting the telephone cable

into the corresponding socket on the ITB-302 using a standard telephone line connector.

Other telephonic equipment may be connected by inserting a standard connector in the

appropriate ITB-302 socket. This is useful for making calls and checking the line. Its connection

is optional.

For connection to 4-wire lines it is advisable to check input and output connections.

The mixer output should be connected (balanced or unbalanced) to the hybrid's SEND input,

whilst the feedback (RECEIVE) can be connected to the cue input of the same mixer.

To hang-on a line, simply press the

remote control. If the autolock function has been enabled, the unit will automatically hang-on

the line after a few rings.

Once the line has been seized, adjust the send and receive levels by injecting the 1 KHz test

signal with the corresponding button, or with a standard signal, and calibrate the levels for a

near zero reading on the LED meters.

Once the line has been hang-on connection is made and maintained. The MEETING button

connects the line to the meeting circuit. In this configuration, the lines that have the relevant

MEETING button pressed, will be connected to each other enabling an audioconference.

Pressing the

OFF HOOK button a second time, on the front panel or on the remote control, it

releases the line. It is equivalent to putting the handset on-hook.

The remote control allows the AEV ITB-302 to be installed in a conveniently located rack near

the telephone line sockets. Once the levels have been adjusted on AEV ITB-302 , the remote

control allows control of the following functions: on-hook, off-hook, conference mode etc.,

directly from the mixer or from the remote telephone location, for simple and rapid operation.
