Gl2800 manual6/12/2023 Use the Pink Noise generator to check the signal routing and loudspeaker response. To prevent a loud tone through the speakers it is best to do this with the amplifiers turned off. Similarly, you could match the console LR output to a DSP speaker processor by sending the tone to LR, setting the faders for output meters reading ‘0’, and then trimming the processor input for ‘0’ on its meters. The recorder is now correctly aligned to the operating level of the console. Next, adjust the recorder input trim so that its meters also read ‘0’. Press the matrix AFL and adjust the oscillator level until the console monitor meters read ‘0’. Set the matrix LEVEL control to its 3 o’clock ‘0’ position. For example, a recorder, video camera or broadcast feed from the matrix. Use the 1kHz tone to line up the connected equipment. The generator can be routed independently to the various console outputs. This is invaluable in testing the system components and setting up correct gain structure. Includes a useful signal generator able to produce a pure 1kHz sine wave tone, or a pink noise test source.
