For times where loud studio playback is necessary, you can perform the following temporary modifications:
Easy: Adjust volume of studio announce speaker
1.You may need a ladder…or a tall friend. |
|
2. Check the input level on the KRK speaker. Maybe even take a picture so you can remember what level to set it back at. Turn bottom knob to desired volume. |
|
3. Set back to original level when finished and check levels. |
|
Medium: Install portable PA
1.You may need a ladder…or a tall friend. |
|
2. Check the input level on the KRK speaker. Maybe even take a picture so you can remember what level to set it back at. |
|
3. Unplug the XLR cable from the KRK. |
|
4. Plug in XLR extension. |
|
5. Set up speaker stand. |
|
6. Mount speaker on stand. You should get a friend to help with this too. |
|
7. Turn down all inputs before plugging in or turning on speaker. |
|
8. Make sure power switch is off, then plug in AC power. |
|
9. Plug in XLR extension that was originally going to the KRK speaker. |
|
10. Plug speaker power into AC outlet. |
|
11. Turn on speaker. |
|
12. Slowly turn up input 3's volume pot to a comfortable listening level. |
|
13. If there is no sound, turn down input 3's volume pot and go to the control room. |
|
14. In the control room make sure the correct studio is routed to send the audio to the desired studio. In this picture, 4B is being selected. Then try slowly turning up the speaker again. |
|
15. If you still can't hear anything. Make sure a source is playing. |
|
16. If you still can't hear sound, make sure A, EXT 1 is selected above the studio knob and slowly turn up the studio knob. Then slowly turn up the speaker pot. |
|
17. Return system to the way you found it and check levels. |
|
Advanced: Connect studio announce to AV system
text here: remind them to use great caution. I suggest you show a mackie between the KRK XLR source and the RCA input into the classroom AV aux in. This would give them a easy to grab volume knob and would handle the conversion from balanced to RCA and any necessary trims. Suggest they contact staff for assistance. Remind them to reconnect KRK and check levels. Alternately, we have some Rolls MB15b upstairs in CMB7 which could be operationalized into checkout / proctors.
If you need it even louder, this should work for you.
1. Find a Mackie mixer. |
