send-to-hybrid 1 audio will be on the LED bargraph labeled 1and the send-to-
hybrid 2 will be on the LED bargraph labeled 2.
• Observe the levels on these two meters. You will note that the highest peak level
reading is represented by a “floating” LED that persists near the top of the meter.
Since our goal is to set the levels so that peak levels do not hit 0dBfs, this peak
reading is what we need to watch. Section 7.1 has more information on the
TWOx12’s metering.
• First set the Input Gain selection found in the Audio Settings menu to a nominal
level close to that used in your facility (i.e. –7, 0, +4, or +8 dBu). This control sets
the level for both inputs. If the inputs are not reading identically, you will need to
adjust them at the output of the console. Note that the lower this selection is set,
the higher the levels on the unit’s meters, as this setting represents nominal input
level.
Next, adjust your console output (mixing desk) level (for the mix-minus) if
necessary. We suggest that you keep the peak level below a -6 to -7 reading, this
will allow some room for error on the part of your operators. If you are using a tone
to set levels, you may need to set them considerably lower. NOTE: Clipping must
be avoided or hybrid performance will suffer.
• Set the right meter to STUDIO OUT, if necessary, by pressing the button located on
the meter. You should see the audio from the phone line on these LED bargraphs
(since we are connected hybrid 1 to hybrid 2 the audio will be reversed. The audio
sent to hybrid 1 will return on hybrid 2 and will be on the LED bargraph labeled 2
and the audio sent to hybrid 2 will return on hybrid 1 and will be on the LED
bargraph labeled 1. Bring up the fader for hybrid 1 on your console.
• Adjust the TWOx12’s Output Gain adjustment found in the Audio Settings screen.
This sets the level for both outputs. Once you have set hybrid 1 pull that fader
down and bring up the fader for hybrid 2. If the sources are not reading identically
you will need to adjust the input trim of the console on one of the two input
channels.
• You can drop the call you made in the previous section. Push the right Drop
button.
3.7 Time to test it out!
Ok, you made it! Another hour and you can go home for the day! First we will check that
the mix-minus for each hybrid is correct. Then we will make a test call.
• Confirm that the Desktop Director you will be using has power and says “Talent”
at the top of the screen. If it says “Producer” follow the directions in Section 4.1.3
to change this Director to “Talent” mode.
• Next, pick up the handset and press the left Line 1 button to select that line for
dialing. You should now hear dial tone on the handset.
• Enter the phone number for a telephone line which has audio present, using the dial
pad (calling either the time or weather service works well for this).
• Press the left Line 1 button and hang up the handset to place the call on hybrid 1.
• Bring up hybrid 1 on the console. You should hear the audio from the phone line.
