PS1 Power Stand Test Cables (continued)
2. XLR Microphone Input Test Cable
Parts needed:
1 - XLR male connector
1 - Dual banana jack
18 AWG shielded twisted pair wire, 6 feet
This cable is used to test the channel 1 and 2 microphone inputs on the PS1 Power Stand.
These input jacks are dual purpose jacks that will accept either XLR or 1/4” TRS phono jack
balanced inputs.
Connect the dual banana jack’s positive (+) connection to pin 2 of the XLR jack. Connect the
dual banana jack negative (-) connection to pin 3 of the XLR jack. Connect the cable shield to
pin 1 of the XLR jack.
3. Line Input 1/4” Phono Jack Test Cable
Parts needed:
1 - Mono 1/4” phono jack
1 - Dual banana jack
18 AWG shielded twisted pair wire, 6 feet
This cable is used to test the channel 1 and 2 line inputs on the PS1 Power Stand.
Connect the dual banana jack’s positive (+) connection to the tip connection of the 1/4” phono
jack. Connect the dual banana jack negative (-) connection to the ring connection of the 1/4”
phono jack.
4. Insert Jack Test Cable
This cable is used to test the channel 1 and 2 insert jacks on the PS1 Power Stand. When you
plug it into the channel 1 or channel 2 insert jack, you will be able to separate the sections of the
electronics. Refer to the PS1 Power Stand block diagram on page 3. The RETURN dual banana
jack will give you the output of the circuitry up to the output of the 2 channel digital volume
control. The SEND dual banana jack will allow you to input a signal to test the circuitry after the
insert jack, which is the input to the A/D
converter and DSP.
Parts needed:
1 - Tip/Ring/Sleeve (stereo) 1/4” phono jack
2 - Dual banana jacks
Shielded stereo cable, 6 feet
For each of the shielded stereo pairs of wires, connect the dual banana jack’s positive (+)
connection to the center conductor. Connect the dual banana jack’s negative (-) connection to
the shield wires. Use an Ohmmeter to determine which of the center conductors is connected to
the ring of the 1/4 inch TRS phono jack. Using a permanent black magic marker, label this dual
banana connector SEND. Determine which of the center conductors is connected to the tip of
the 1/4 inch TRS phono jack. Label this dual banana connector RETURN. The sleeve portion of
the jack is the common ground where the shields are connected.
