powers off automatically
~1 minute after the audio signal is
"not" detected. This off action creates a slight mousey
squeak, turning on is very clean. The built in 1 watt
power amplifier is what makes this acoustic
resonator simple and practical.
There appears? to be
a power jack on the
amplifier mini pcb though it is not mentioned in
the literature? At 3 volts I might add a dual D cell holder
for years of lasting power if there is an issue of battery life.
From the EtherWave
output is a 1/4" phone plug adapter to 3.5mm stereo to
TRS Y adapter. One leg of the Y goes to an inline
to adjust the level driving the Amplified
on the back of the bucket. The other Y end goes to the
right channel of the Sound
Card or Mixer
bucket uses a Cherub Pickup on the bucket, it's 1/4" phone
plug goes to the Mixer
input #2. This will amplify the pickup signal to Line
Pot #2 fully clockwise.
To the Main
Amplifier from the Mixer
need the proper length cable with the standard
1/4" phone plug going from the Mixer
Output to the amp with the two
channels that have been mixed.
You also need a short cable with a
phone plug for the Mixer input #1 and the other end a mono
3.5mm plug to go to the 3.5mm Y adapter at the EWS.
To your Sound
a 3.5mm stereo male plug with two RCA
male on the other end. Order the proper cord length. $3.35
plug to RCA female $2.95
ad-on Mixer output to connect
to the Acoustic left channel to sound card.
male mono to RCA female $4.99
ad-on for the direct right channel
Original sound to sound card.
3.5mm mono plug works fine in a stereo jack . A
3.5mm stereo plug in a 3.5mm mono jack can
create intermittent contact.
needed are listed in the table boxes above, a photo
for the setup will be posted.
speaker transducer manufacture recommends
very high bond adhesive tapes like 3M-9473PC
to bond to surfaces. I think using #6 screws and nuts on the four
feet for what we are doing is better.
If only acoustic coupling
is used it eliminates the need of a Ground Loop Filter but still
giving a very clean sound.
Other pickups to be
mixer 12 volt regulated power supply. Amazon
Center $19.99 (12
volt wall-wart might be used for the Phoenix)
A stereo Eq-PreAmp
might be useful by connecting the output from the EtherWave
through the Eq right
the resonant board speaker
and connecting the Eq left
between the resonant board/bucket Piezo
the Mixer or Main amp or Sound card.
wave audio signal through the speaker
might be a more effective sound. This should be ~.5
