Front and rear panel 5 Front and rear panel This section explains the names and functions of each section of the GF24/12, GF16/12, and GF12/12. The functionality of these mixers is grouped into ten sections. These are the two chan- nel control sections, seven master control sections, and the rear panel connectors. Their functions will be explained sequentially. Front panel 679 POWER PEAK PEAK 1 2 3 4 5 6 7 8 9 10 11 17 18 19 20 21/22 23/24 +8 +8 +5 +5 +3 +3 +1 +1 A A 0 0 26dB 26dB 26dB 2
