13.3 Verify that the audio comes from the upper section of the L1 line array. The audio should sound clean and undistorted.
13.4 Connect the audio source to the Amp 2 IN 1/4 inch phono jack. Verify that the audio comes from the lower section of the L1 line array. The audio should sound clean and undistorted.
13.5 Connect a B1 bass module to the PS1 power stand at the Bass/Amp 3 OUT jack. Connect the audio source to the Amp 3 IN 1/4 inch phono jack. Sound should come from the bass module only and be clean and undistorted.
13.6 Connect the audio source to the All Amps IN 1/4 inch phono jack. Sound should come from both of the L1 line array sections and the bass module simultaneously. The audio should be clear and undistorted.
14. High SPL System Sweep Test
CAUTION: This test will be extremely loud.
Hearing protection is advised.
14.1 Connect a R1 remote control to the PS1 power stand under test. Set the chan­nel 1 controls to mid-level. Set the master volume control on the remote to the 1 o’clock position. Set the channel 1 Mic Trim control on the PS1 to 6. Connect a L1 line array to the PS1. Connect a B1 bass mod­ule to the PS1.
14.2 Connect a signal generator to the channel 1 input on the PS1. Adjust the signal generator and/or trim control so that the Signal/OL LED is just below red.
14.3 Sweep the input frequency from 40 Hz to 14 kHz. Listen for any unusual noises and excessive distortion or drop-outs.
15. Bass Module Auto-EQ Test
15.1 Connect a L1 line array to the PS1
power stand. Connect an R1 remote control to the power stand. Connect a B1 bass module to the Bass/Amp 3 OUT jack on the power stand. Connect an audio source to the channel 1 and 2 inputs of the power stand.
91
Test Procedures
15.2 Set the channel 1 and 2 level controls
to identical settings so that both LEDs are mainly green.
15.3 While the audio is playing, disconnect the B1 bass module from the power stand. The system should mute and un-mute and audio should resume. The audio should sound normal, but not punchy (no deep bass).
15.4 Plug a dummy 1/4 inch phono jack into the Bass Line Out jack. The system should mute and un-mute again, but the audio should sound thinner than before.
15.5 Remove the dummy plug. The system should mute and un-mute and the audio should sound normal again.
15.6 Re-connect the B1 bass module to the power stand. The audio should mute and un­mute again and sound normal.
15.7 Connect a second B1 bass module to the first one. The audio should mute and un­mute. The audio will sound very similar to having only one bass module attached. Disconnect the second bass module. The system should mute and un-mute and the audio should sound normal again.
L1 Line Array Tests
Set up the unit under test as shown below.
1. Air Leak Test
1.1 Apply a 100 Hz, 10 Vrms sine wave to
the unit under test.
1.2 Listen carefully for air leaks from around the end cap, the transducers and the grille. Air leaks will be heard as a hissing or sput­tering sound. All repairs must be hidden. Test duration should be 5 seconds minimum.
2. Transducer Rub and Tick Test
2.1 Remove the transducer you wish to test
using the disassembly procedures in this manual. Do not unplug the wires at the transducer assembly terminals.
2.2 Connect a signal generator directly to the terminals of the transducer assembly under test.
2.3 Apply a 20 Hz, 5 Vrms signal to the transducer assembly.
2.4 Listen carefully for any extraneous noises such as rubbing, scraping or ticking.
Note: To distinguish between normal sus­pension noise and rubs or ticks, displace the cone slightly with your fingers. If the noise stays the same, it is normal suspension noise and the driver is good. Suspension noise will not be heard with program mate­rial.
3. Transducer Phase Test
3.1 Apply a DC voltage of 10V, positive
applied to the positive tab of the dual banana jack on the line array test cable and negative applied to negative (gnd) tab.
3.2 All of the driver cones should move outward when the DC voltage is applied.
3.3 Rewire any incorrectly connected trans­ducers.

PS1 Power Stand Test Cables
Note: In order to be able to properly test the PS1 Power Stand, you will need to make up a few
test cables.
1. Amplifier Output Test Cable:
Parts needed:
1- Neutrik NL4FX Speakon X-Line/4 Pole connector. 4 - Dual banana jacks 2 - 10k ohm, 1/4 Watt resistors 16 or 18 AWG twisted pair wire, 6 feet 18 AWG twisted pair wire, 2 feet
This cable is used to connect the Amp 1 OUT, Amp 2 OUT or Bass/Amp3 OUT jacks to the load resistors used in the test procedures. The connector used is a Neutrik NL4FX Speakon X-Line / 4 Pole type. This connector has 4 terminals labeled 1+, 1-, 2+ and 2-. Terminals 1+ and 1- are used to connect to the load resistors. Use 18 or 16 AWG wire for these terminals. Use twisted pair wires to avoid inducing noise into the cable during use.
The 2+ and 2- terminals will be used to sense the loads connected to the Speakon connector when used with the Bass/Amp3 OUT jack. This jack automatically senses the load on this jack to properly tailor the EQ and output level for the connection of one or two bass modules. It does this by sensing the resistive value across terminals 2+ and 2-. The bass modules have a 10k ohm resistor across these terminals. When only one bass module is connected, the PS1 sees the 10k resistance and sets the EQ and output level accordingly. When two bass modules are connected, it sees 5k and sets the EQ and output level accordingly. For the test cable, you will use 18 AWG twisted pair wire to a dual banana jack.
It is also useful to have 3 spare banana jacks, one with a short across it and 2 with a 10k Ohm, 1/4 Watt resistor each to simulate a bass module connected to the terminals. The Amp 1 OUT and Amp 2 OUT jacks to not sense this load.

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 78. 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.
