Telos NX12 - Manual (Page 23)

InsTallaTIon | 13
The Nx12 has multiple hybrids and works best if two faders can be assigned to the telephone
system with two associated mix-minuses, one for each telephone line column on the Director.
This is probably not going to be easy with an older console. But the Nx12 has an option to work
with a single external mix-minus by making an internal cross-connection of the hybrids. See
Section 5.7 for more on this.
Using a small mixer
In this scenario, a small audio mixer is used to record interviews off the telephone line using a
single hybrid. The mixer’s main bus is fed to the recording device. Both the microphone and the
hybrid will be brought up on the faders so the interview can be recorded.
Most small mixers (such as those made by Mackie) have one or two Aux send busses, so we will
use these to feed the telephone system. We will turn up Aux for the microphone but we will
make sure it is turned fully off for the each channel that has the corresponding caller audio.
Using a production-style console
The production-style consoles often used for TV audio will have multiple Aux send busses that
can be used in a similar way to the small mixer example above. Each hybrid is sent from an Aux
bus and everything the caller needs to hear is mixed into that bus, taking care to keep the hybrid
itself off the bus.
Phones and Remotes
When on remote, to save money and hassle, calls are usually received at the studio, rather than
at the remote site. In this situation, caller audio must be fed to the remote talent so that they
can hear and respond to callers. Moreover, the callers need to hear the talent. In many cases, the
remotes are sufficiently distant that talent cannot monitor the station for the caller feed. Even
