DIAGRAM III-4: EQUALIZING SPEClFIC MICROPHONE/SPEAKER
COMBINATIONS
*NOTE: Be sure to use CHANNEL 2 when using the RE 14 in this test configuration.
4. The above configuration can be used for main speaker equalization to optimize system response for a
specific microphone used throughout the system, such as for choir, orchestral or big band situations
where all program material is picked up through microphones of the same make and model Patch the RE
27 or RE 14 (using channel 2 of the RE 14) into a SEND/RECEIVE loop as shown by the dashed lines, but
make the final output connection for the equalizer to the MAIN amp(s) and speakers instead of the
monitor system as shown.
3. Mixers that do not have separate SEND/RECEIVE capability for each channel will have to be wired as
shown in Diagram I I l-3.
2. Dashed lines show temporary connections for pink noise test purposes only; repeat this configuration
for each microphone input channel. When testing is completed, connect the RE 27 or RE 14 as indicated
by solid lines.
1. Using this test configuration allows the analyzerto look at the specific relationship between each stage
microphone/speaker combination. Since both the microphone and stage monitor speaker will exhibit
their own individual feedback tendencies, the inter-action between the two can cause pronounced
feedback problems. The above configuration will allow you to flatten or “normalize” this interaction
without actually getting to feedback levels (which is desirable in many situations). It should be noted that
this testing procedure will favor maximum SPL before feedback and not necessarily optimum monitor
sound quality.
HEAVY LINES INDICATE DIRECT CONNECTIONS TO THE RE 27 and RE 14. Thinner lines show other
connections for clarity.
