If you are connecting to a mixing console's main inserts, you may have a single TRS jack for SEND & RETURN,
in this case, use an insert "Y" cable that configured like the examples below.
The most secure mounting is on a universal rack shelf available from various rack manufactures or your music
dealer. The EQU Series fits into one standard 19" rack unit of space, but the EQU131 and EQU215 will be 1H
height, the EQU231TWIN will be 4H height, while the other four models: EQU2215, EQU131VU, EQU231VU and
EQU231LED will be 2H height. Please allow at least an additional 4" depth for the connectors on the rear panel.
Be sure that there is enough air space around the unit for sufficient ventilation and please do not place the EQU
Series on high temperature devices such as power amplifiers etc. to avoid overheating.
