Trident 80B-500EQ

The Series 80B 500 Series EQ incorporates a classic four band equaliser which is identical to that employed in the Trident Series 80 console. It consists of frequency switchable high and low pass shelving sections, coupled with two swept low and high mid range bands and a switchable 50Hz, 12dB per octave filter. Both swept midranges have been carefully chosen for maximum effect on music programme and a good degree of overlap is provided.   Begin with all boost/cut controls – those with centre detents, set to their mid way (‘0’) positions. Adjust the low and high mid frequency sweep controls to their minimum positions (fully anticlockwise). The50Hz high pass ‘Filter‘ switch should be in the out position. Set the frequency select switches controlling the high and low shelving sections, to 120Hz and 12kHz respectively. Lastly, set the ‘EQ’ switch to the ‘in’ position (the associated LED will illuminate). Rotation of the high frequency shelving control in a clockwise direction emphasis
