Center position is detented and grounded for guaranteed flat response. 2 Filter RANGE switches: The gain range of the filter sliders is switchable (as a group) from ±6 dB for high resolution, to ±12 dB for maximum boost/cut capability. [. . . ] It is not necessary to short any inputs to ground--it doesn't hurt, it's just not necessary. Use pin 1, or the shell, for shield ground. Balanced output requires using pin 2 or tip, and pin 3 or ring for the signal. The signal exists differentially between the two balanced leads; ground is not involved. For hum-free systems ground is used only for shielding. EXPANDING Expanding and/or daisychaining the Inputs and Outputs normally uses the ¼" jacks. Three parallel Input connectors allows driving a second signal processor or amplifier without special cabling. SIGNAL LEVELS Signal levels from -10 dBV to +4 dBu are considered normal and within range (at least 20 dB of headroom exists above these levels). Do not directly connect microphones into the ME 15S. These require a mic preamp. Manual- Operating Instructions Insuring the proper level of gain though the ME 15S is just as important as adjusting the equalizer bands. Improper gain distribution is a common cause of loss of system headroom and less than optimum noise performance. The OverLoad LED informs of an imminent or passed overload to the equalizer. Occasional blinking of the OL with program source material is fine, indicating optimized signalto-noise performance of the ME 15S. Run the ME 15S with an input signal that is as hot as possible without the OL lighting more than occasionally. The BYPASS switch allows comparison of equalized versus un-equalized signal. It is also useful in adjusting the level of the ME 15S for unity gain and best signal-to-noise performance. The gain of the ME 15S is optimized when there is no sound level difference between the bypassed and the active positions. The overall gain range of the level control for the ME 15S is off to +6 dB for unbalanced operation, or off to +12 dB for balanced operation. The level difference between the equalizer in bypass or active can be significant. Adjust the LEVEL control so the signal level is the same between the bypassed and active positions of the BYPASS switch. GETTING STARTED Here is one method of setting your equalizer that works well. Put all sliders in their center position (0 dB). [. . . ] In addition, boosting low frequencies can make your power amplifier run hotter, leading to premature amplifier failure. When equalizer adjustment is completed, compare the unequalized sound with the equalized sound by alternately engaging the BYPASS switch. Use familiar source material and walk around in the sound coverage area to insure that no anomalies have been introduced into the sound system. TONE CONTOURING If a ME 15S is used for tone contouring by ear, be careful about adding upper bass (63 Hz to 200 Hz) as this causes "muddiness" or loss of definition. [. . . ]
