Chapter 15 Talkback / Oscillator This chapter explains how to use the talkback and oscillator functions. About talkback and oscillator Talkback is a function that sends the signal of the selected INPUT jack to the desired bus. This is used mainly to convey directions from the operator to the performers and staff. The LS9 also contains an oscillator that allows a sine wave or pink noise to the desired bus, and this can be used to check external equipment or to test the response of the room. The diagram below shows the signal flow of the talkback and oscillator. +48V +48V MASTER ON [INPUT] INPUT 1 2 [1-16{32}] 3 +48V + - HA METER AD GAIN/TRIM TALKBACK INPUT 1-16{32} INPUT SELEECT ON MIX 1 2 ...15 16 M O ST N O MATRIX CUE L R (C) 1 2 ... 7 8 L R OSCILLATOR Sine Wave Pink Noise Burst Noise HPF LPF OSC LEVEL METER ON Using talkback Here's how a signal received at an INPUT jack 1-16 {1-32} can be output to the desired bus. 1 In the DISPLAY ACCESS section, press the [MONITOR] button repeatedly to access the TALKBACK screen.
