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.

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 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.

PS1 Power Stand Software Update Procedure

Required Equipment:

1- CD player with a S/PDIF digital output (do not use a Bose® Lifestyle® media center) 1- PS1 Power Stand update CD (see the instructions for creating this disc below) 1- S/PDIF video cable, part number 183200, or an audio cable with RCA connectors 1- PS1 Power Stand AC line cord, part number 273790

PS1 Power Stand Update CD Procedure:

• Go to the Bose Technical Service web page at http://intranet.bose.com/tsg (Bose internal

repair centers) or http:serviceops.bose.com (external Bose affiliated repair centers).

• Navigate to the Personal Amplification System web page. The link to it is located on the

Pro Products web page.

• Scroll down the page until you see the table that the link to the PS1 Power Stand software

update is located in. Download the file to your computer’s desktop.

• Using a CD burner and your CD burner software, burn the file onto a blank CD-R or CD-RW

disc. Once this disc is successfully created, label the disc with the revision of the software.

Update Procedure:

• Plug the CD player into an AC mains outlet.

• Connect the S/PDIF cable to the Audio Outputs/Digital jack on the back of the CD player.

• Connect the other end of the S/PDIF cable to the DATA IN jack on the PS1 Power Stand’s input

panel. This jack is located in the middle of the panel. It’s an RCA jack with a white center.

• Connect the PS1 Power Stand’s AC line cord to the AC mains jack on the PS1 input panel.

This jack is located on the right side next to the power switch.

• Connect the other end of the AC line cord to an AC mains outlet.

• Power up the PS1 Power Stand by moving the power switch to the ON position. Wait for the

power LED to light steady green.

• Load the update CD into the CD player. Press the PLAY CD/DVD button on the remote

control. The update process should begin.

• Wait about 5 seconds while the disc is playing. The green power LED on the PS1 Power Stand

should blink rapidly, about 10 times per second. After about 10 seconds, the LED should begin to blink slower, about twice a second.

• The update process is complete. Power down the PS1 Power Stand. Disconnect the S/PDIF

cable from the DATA IN jack.

• Verify proper operation of the PS1 Power Stand using the test procedures in this service

manual before returning the unit to the customer.

Troubleshooting:

Problems with this update procedure are indicated by the PS1 Power Stand’s power LED. Typical indicators are:

• LED stays a steady green.

• LED blinks slowly red

In either case, simply repeat the process above. Make sure you wait 5 seconds after power up of the PS1 Power Stand before playing the update disc. Ensure all of the cables are properly connected.
