1. SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.
ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER.

LEAKAGE CURRENT CHECK

Measure leakage current to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester such as Simpson Model 229-2 or equivalent between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5mA.

2. PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in the appliance have special safety related characteristics. These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this Service Manual. Electrical components having such features are identified by marking with a on the schematics and on the parts list in this Service Manual. The use of a substitute replacement component which does not have the same safety characteristics as the PIONEER recommended replacement one, shown in the parts list in this Service Manual, may create shock, fire, or other hazards. Product Safety is continuously under review and new instructions are issued from time to time. For the latest information, always consult the current PIONEER Service Manual. A subscription to, or additional copies of, PIONEER Service Manual may be obtained at a nominal charge from PIONEER.

Operation

This section shows you how to use every feature of the receiver and its remote control unit. It also covers using the supplied remote control to operate your other Pioneer home theater components. To find out more about a specific button, control or indicator, see Displays & Controls starting on page 17. This will point you to the relevant chapter in the manual. In the Additional Information section (p.38-40) you'll find a troubleshooting section and specifications.
Preparing the Remote Control

Loading the batteries

Dry cell batteries ('AA' size IEC R6P 2)

CAUTION!

Incorrect use of batteries may result in such hazards as leakage and bursting. Observe the following precautions: Never use new and old batteries together. Insert the plus and minus sides of the batteries properly according to the marks in the battery case. Batteries with the same shape may have different voltages. Do not use different batteries together.
Operating range of remote control unit
memo The remote control may not work properly if: There are obstacles between the remote control and the receiver's remote sensor. Direct sunlight or fluorescent light is shining onto the remote sensor. The receiver is located near a device that is emitting infrared rays. The receiver is operated simultaneously with another infrared remote control unit.
Special note on the remote control
Please note that the remote control has two types of buttons, one called FUNCTION and a set of buttons called SOURCE SELECT. Use the FUNCTION button to choose the component you want to listen to (CD, CDR/TAPE, TUNER, etc.) and use the SOURCE SELECT buttons to change which component the remote control itself will operate. Thus, if the VSX-409RDS is in TUNER mode, for example, and you want to listen to your CD player, you need to select the CD mode with the FUNCTION button.
Operating other Pioneer components
By connecting a control cord (optional), you can control other Pioneer equipment using this remote control unit. Point the remote control unit towards the remote sensor of this unit, even when operating other equipment. The remote control signals are received by the remote sensor of this unit, and sent to the other devices via the CONTROL OUT terminal.

Listening in Surround Sound
Listening in Dolby Pro Logic Mode
To really appreciate what the VSX-409RDS can do, sit back and experience a movie encoded in Dolby Digital or Dolby Pro Logic with five speaker surround sound creating theater-like sound effects in your living room. When mark on DVD discs, laser discs, and video tapes choosing software, look out for the (sometimes, unmarked software is also recorded in Dolby Pro Logic). To enjoy Dolby Digital surround sound from DVD discs, you'll need to have connected your DVD player (or Dolby Digital decoder) to the receiver's 5.1 channel inputs (see page 9), and set the receiver to DVD 5.1 CH input mode. Many video tapes feature Dolby Surround/Pro Logic these days. The VSX-409RDS takes advantage of this to provide dramatic and realistic surround sound. The effect can be further enhanced by choosing a Pro Logic with DSP mode. Follow the steps on this page when playing Dolby Surround or Dolby Pro Logic material. When using any of these modes, it's really important that your speakers are set up correctly (see p.11-12), and that you've worked through the steps in Setting Up for Surround Sound on pages 13-15.

Listening in DVD 5.1 Channel Input Mode
Some DVD players feature a built-in Dolby Digital decoder with separate analogue audio outputs for the front left and right, centre, surround left and right, and sub-woofer channels. Connect these to the 5.1 channel inputs of the VSX409RDS for enhanced playback of Dolby Digital materialsee page 9 for instructions on connecting up.5.1 channel mode of the VSX409RDS provides better surround-channel sound and overall channel separation than the Dolby Pro Logic mode. Follow the steps below to use the 5.1 channel mode.
1 Use the FUNCTION button to select DVD 5.1 CH.
SOURCE SOURCE SELECT TUNER DVD CD TV CONT. TAPE MD CD-R
On the receiver, press the DVD 5.1 CH function button to select the DVD input mode directly. On the remote control, repeated presses of the FUNCTION button switches between 5.1 channel input and the other inputs.
You can input level settings specifically for your 5.1 CH mode and this will enhance you surround sound experience (see p. 15). You can't use the tone controls S.BASS, DIRECT, DSP, or the PRO LOGIC functions with 5.1 CH mode.

Listening in DSP Mode

The DSP (Digital Signal Processing) modes transform your living room into a variety of different sound environments when playing standard (two channel) stereo sources. Optionally, you can adjust the amount of effect added to the source. The descriptions below give an idea of what the five different modes sound like, but the best idea is to play a source and experiment.

Simulates the acoustic environment of a large classical concert hall. Long delay and reverb decay times create a sense of music being played in a large space.
Simulates the acoustic environment and strong bass sound of a dance music club.

THEATER 1

Simulates the acoustic environment of a mid-sized movie theater.
Simulates the acoustic environment of a jazz club. Shorter delay times and a tighter reverb help to give the sound a live, small club feel.

THEATER 2

Similar to the above but maintains proper localization of each channel.

1 Select a DSP MODE.

Repeated presses of DSP MODE changes the DSP mode in the following sequence:

3 HALL

DSP OFF

3 JAZZ

3 DANCE 2
3 Use the EFFECT +/ buttons to adjust the DSP effect level.
All DSP effect levels are independent of each other. You can input level settings specifically for each DSP mode and this will enhance your surround sound experience. If you turn the speakers off, DSP goes off as well. When the speakers are off you can't use the DSP mode. You can't use the tone controls, the DIRECT function with DSP mode.

Using the Tuner

Finding a Station
The following steps show you how to tune in to FM and AM radio broadcasts using the automatic (search) and manual (step) tuning functions. If you already know the exact frequency of the station you want to listen to, see Tuning Directly to a Station on the following page. Once you are tuned to a station you can memorize the frequency for recall latersee Memorizing Stations on page 25 for more on how to do this.

2 Press the TUNER button on the remote control to put the remote control in tuner mode. 3 Press CLASS to select the class in which the station is stored.
4 Use the STATION +/ buttons to select the station memory in which the station is stored.
Alternatively, recall the station memory using the number buttons on the remote control.
If the receiver is left disconnected from the AC power outlet for a lengthy period, the station memories will be lost and will have to be reprogrammed.
An Introduction to RDS & EON
Radio Data System, or RDS as it's usually known, is a system used by FM radio stations to provide listeners with various kinds of informationthe name of the station and the kind of show they're broadcasting, for example. This information shows up as text on the display, and you can switch between the kind of information shown. Although you don't get RDS information from all FM radio stations, you do with most. Probably the best feature of RDS is that you can search automatically by type of programme. So, if you felt like listening to jazz, you could search for a station that's broadcasting a show with the programme type, "JAZZ." There are around 30 such programme types, including various genres of music, news, sport, talk shows, financial information, and so on. The VSX-409RDS receiver lets you display three different kinds of RDS information: Radio Text, Programme Service Name, and Programme Type. Radio Text (RT) is messages sent by the radio station. These can be anything the broadcaster choosesa talk radio station might give out it telephone number as RT, for example. Programme Service Name (PS) is the name of the radio station. Programme Type (PTY) indicates the kind of programme currently being broadcast. The VSX-409RDS can search for and display the following programme types:

News Affairs Info Sport Educate Drama Culture Science Varied Pop M Rock M M.O.R. M Light M Classics Other M Weather Finance Children Social A Religion Phone in Travel Leisure Jazz Country Nation M Oldies Folk M Document
Current affairs General information Educational material Radio plays or serials Science and technology Usually talk-based material, such as quiz shows or interviews. Pop music Rock music Middle of the road music Light classical music Serious classical music Other music not fitting any of the above categories stock market reports, commerce, trading, etc. Childrens entertainment Social affairs
Holiday-type travel rather than traffic announcements. Leisure interests and hobbies Country music Popular music in a language other than English Popular music from the 50s Folk music Documentaries
In addition, there is a programme type, ALARM!, used for exceptional emergency announcements. You can't search for this, but the tuner will switch automatically to this RDS broadcast signal.

Using the RDS display

To display the different types of RDS information available (RT, PT and PTY as explained on the previous page), press TUNER on the remote control and use the DISP button (also marked 3) to cycle through the types of RDS information. Each press changes the display as follows.
3 RT 3 PS 3 PTY 3Frequency

Basics of EON

EON (Enhanced Other Network information) EON is a function that allows you to set the receiver to switch to a frequency automatically when a programme featuring traffic information or news is being broadcast. It cannot be used in areas that EON information is not transmitted and when FM broadcast stations do not transmit PTY data. When the broadcast ends, the tuner returns to the original frequency or function. There are two types of EON you can set the tuner to: 1) TA (Traffic Announcement) This mode will set the tuner to pick up traffic information when it is broadcast. 2) NEWS This mode will set the tuner to pick up news when it is broadcast. Setting EON allows automated reception of TA/NEWS broadcasts When EON is turned on, the receiver will automatically jump to those EON-linked broadcasts. Even if a receiver function other than the tuner is being used, the receiver function will switch to the FM station automatically when an EON-linked Traffic Information or News programme begins. When the programme ends, the original function will be restored. The EON function will not operate, however, when the the tuner is on AM.

The receivers internal Program Identification function
PI (Programme Identification) This is an identifying marker the tuner automatically attaches to stations stored in your preset memory classes (see p. 25). The marker distinguishes between stations which transmit RDS data and those that dont, so that the receiver knows which stations to look at when searching for RDS or EON transmissions. The code is not displayed on the reciever and you dont need to do anything in regards to setting the PI codes. PI code registration and erasure The receiver will automatically register a PI code for any station you input into the memory classes (see p. 25) which can receive RDS or EON data. If you want to have a station preset in your memeory banks but DONT want the receiver to search this station for RDS information you can erase the PI code and then the receiver will ignore this station when searching for RDS transmissions. To erase PI codes, follow this procedure: 1. When tuned to the station whose PI code you want to erase press the EON MODE button for two seconds or more. ERASE PI will be displayed. 2. Press MEMORY button within 5 seconds.
Searching for RDS Programmes (front panel only)
One of the most useful features of RDS is the ability to search for a particular kind of radio programme. You can search for any of the programme types listed on page 27this covers all kinds of music, as well as news, weather forecasts, sports programmes, and a variety of others.
1 Put the receiver in FM band by pressing the FM/AM button.
RDS is only broadcast on FM.
2 To select the PTY search mode press the CHARACTER/SEARCH button until you see SEARCH in the display.
If you are on a preset station youll have to press the button twice, if not then one press will bring up the PTY search mode.
3 Use the STATION +/ buttons to select the programme type you want to hear.
4 Press MEMORY search for the programme type.
The tuner searches through the FM stations stored in the station memories. If the tuner finds a matching programme type, the tuner plays 5 seconds of the station. To listen to that station, press the CHARACTER/SEARCH button. (The tuner stops searching.) If you don't press the CHARACTER/SEARCH button during the above metioned 5 seconds, the tuner resumes the search. When the tuner finds a programme type you searched for, the frequency display will blink for about 5 seconds and then the display will show FINISH briefly.
If NO PTY is displayed it means the tuner couldnt find that programme type at the time of the search.
The tuner stops on any station that is broadcasting that programme type
This function searches RDS stations preset in the 30ch memory. If this function is set when no stations have been preset, NO PTY will be displayed. If the desired PTY could not be found amongst the RDS stations in memory, the same display appears.
