7. Range Switch -When depressed, this switch will multiply the selected crossover frequency by 10.The LED will light indicating that the markings on the Frequency knob (6) should be multiplied by 10. 8. Channel 2 Gain -This is the input level for Channel 2 in Stereo mode. In Mono mode this knob has no function. 9. Low/Mid Level -This knob controls the volume for the Channel 2 low frequency output in Stereo mode, and the mid-range frequency output volume in Mono mode. 10. High Level -This knob co

The lightning flash means that there are dangerous voltages present within the unit. The exclamation point indicates that it is necessary for the user to refer to the owners manual. These symbols warn that there are no user serviceable parts inside the unit. Do not open the unit. Do not attempt to service the unit yourself. Refer all servicing to qualified personnel. Opening the chassis for any reason will void the manufacturer’s warranty. Do not get the unit wet. If liquid is spilled on the uni

A 1/4" TRS jack may be used to achieve an impedance balanced output. Maximum balanced output level is +21 dBu. Balanced output impedance is 102 . . UNBALANCED OUTPUT: Accepts a 1/4” plug (see section on installation for wiring connections). Connections are unbalanced. Maximum unbalanced output level is +21 dBu. Output impedance is 51 . unbalanced. 8SR Series ATTENTION: DO NOT USE BOTH THE BALANCED AND UNBALANCED INPUT/OUTPUT JACKS TO A CHANNEL AT THE SAME TIME. Using more than one connector at a

B. Greater gain-before-feedback characteristics can be achieved by turning up the sound system to the feedback point and attenuating the oscillating (ringing) frequency. 1/3rd octave resolution is best for this application. Turn the system up to feedback again and attenuate the second oscillating frequency. Repeat the process again for the third oscillating frequency. C. Protection of amplifiers and speakers can be accomplished using the LOW CUT feature of the equalizer. Wind noise or sub sonic

Dual channel units may be used as a stereo equalizer or as two independent equalizers. The units offer either 1/3rd octave or 2/3rds octave resolution, depending on the unit chosen. All DOD equalizers are solidly built with steel chassis and CSA standard circuit boards for years of reliable service. WHY A 1/3RD OCTAVE OR A 2/3RD OCTAVE EQUALIZER? Most graphic equalizers divide up the audio frequency range into 1/3rd octave or 2/3rds octave pieces. One octave covers a 2-to-1 range of frequencies.
