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 is working and says Talent at the top of the screen. If it says Producer, follow the directions in Section 4.1 to change this Director to Talent mode.

♦♦ Next, pick up the handset and press the left column line 1 button to select the 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 keypad (calling either the time or weather service works well for this).

♦♦ Press the left column line 1 button and hang up the handset to place the call on the Phone 1 output.

♦♦ Bring up Phone 1 on the console. You should hear the audio from the phone line.

♦♦ Look at the Input 1 meter on the Nx12 and verify that this audio is not present. If the phone audio is seen here, you are not feeding a mix-minus and you must fix this problem before you proceed.

IMPORTANT

If you are using one of the mix-minus schemes that require only a single mix-minus you should not have seen audio on either the 1 or 2 bargraphs in the previous test. In that case you can skip the next test. See Sections 2.7 and 5.4 for detailed information about the Nx12’s mix minus options.

Now we will verify the second mix-minus.

♦♦ Press right column line 2 button to move the call.

♦♦ Bring up Phone 2 on the console. You should hear the audio from the phone line.

♦♦ Look at the Input 2 meter on the Nx12 and verify that this phone audio is not indicated here. If phone audio is present here, you are not feeding hybrid 2 a mix-minus and you must fix this problem before you proceed.

♦♦ Drop the call by pushing the Drop button.

Ok, now we just need to test the system as whole. We suggest calling your spouse or partner and reporting that you will be home for dinner after all!
