Call is ON-AIR

Call is ON-HOLD

If the Line Status display indicates “Line not detected” after power-up, the telephone line is not connected to the LINE jack on the back Panel, or line voltage is not detected. Check your wiring and verify that dial tone is present on the line. This function is not compatible with ground start lines or trunks as these do not have loop current or voltage present until the line has been grounded momentarily or is ringing.

3.3 Metering

Each hybrid has its own SND and RCV meters to simultaneously display the studio input audio level, as well as the output level of the caller. Set the input level pot so that 0dbu on your console causes the Hx to display a yellow bar on the SND bargraph. The meter displays audio before any processing.

The output meter indicates audio levels after all processing and EQ. It’s also useful for troubleshooting mix minus and other audio issues. A yellow bar corresponds to +4dbu at the audio output. The nominal output level is fixed at +4dbu.

Each hybrid also has a pair of EQ meters which show that amount of gain adjustment applied to the incoming caller audio in HI and LO frequency bands. When the DDEQ feature is

disabled via the Back Panel DIP switch settings, nothing will appear on the EQ HI and EQ

LO bar graphs.
