Check or briefly answer each of the following items
- I have browsed and read the Audio System web pages.
- I can list some advantages of digital versus analog audio
systems.
- I can identify every component in the rack located in the
Equipment Room of the planetarium, and give a concise explanation
of the function of each.
- I can locate the six jacks near the stage area for microphones
and electronic instruments.
- I can identify the six speakers of the Planetarium by location
(e.g., Left Front) and number (1 through 6).
- True or False?
- RD-8 deck A is the playback deck.
- True or False?
- RD-8 deck B is the record deck.
- What is the number of the correct channel on RD-8 decks for
the cue track (= SMPTE track = Time code track)?
- The Patch Bay allows me to connect any audio source to any
audio destination. I am familiar with the two-bank arrangement of
our patch-bay, and understand the difference between using Normals
and Patch Cables to establish audio connections.
- True or False?
- A patch cable in a send jack breaks the normal connection
from that jack.
- True or False?
- A patch cable in a receive jack breaks the normal
connection to that jack.
- I promise always to turn down the speaker faders on
the mixer before making an audio connection with patch
cables!
- I know the difference between a line-level signal from a DI
box and a mic-level signal from a mic input. I know never to
send a line signal into a mic input!
- I am familiar with the following terms as they relate to the
mixer:
Fader, Input Module, Subgroup, Input Trim, Aux Send, Pre-fade
Send, Post-fade Send, Pan knob, Buss button.
- Counting stereo input modules twice, how many input channels
does our mixer support?
- We have four aux sends currently assigned. How many aux sends
can our mixer support?
- True or False?
- If the Peak Indicator light comes on near the base of any
input module, I should turn down the Input Trim.
- True or False?
- Equalizer knobs should be set flat or straight up most of
the time.
- True or False?
- When someone is using the Hearing Enhancement system, the
second Auxiliary Send knob on most input modules should be
turned up, although the mic may be set higher than others and
music set lower.
- Some space music CDs kept in the planetarium were purchased
with complete in-house production rights, which allows us to
incorporate musical segments in our shows.
- You are working on a show soundtrack, and want to record
onto tracks one and two of an ADAT tape from the left and right
channels of a CD. What patches would you use?
- True or False?
- The fourth Aux Send routes audio to the subwoofer, and
therefore should be turned up for vocal tracks (or for a
voice-microphone).
Activities in the Planetarium
- I have used the patch bay to send stereo sound from the CD
player to both the front and rear speakers (in two stereo pairs).
Describe any patches used:
- I have tested adding reverb to my voice with the Lexicon
channel on the mixer in conjunction with the Beyer Wireless mic.
- I have tested the use of the Wireless microphone, which I will
often use when giving shows (including my semester project
presentation!).
- I am now an audio systems wizard in this planetarium.
