OPERATION
Within five seconds of seeing the DIRECT IN scroll in the Upper Display Line �, enter the station frequency by pressing the Numeric Keys r. If you press an incorrect button while entering a direct frequency, press the Clear Button 33 to start over. NOTE: When the FM reception of a station is weak, audio quality will be increased by switching to Mono mode by pressing the Tuner Mode Button &s so that MANUAL appears momentarily in the Lower Display Line ¯ goes out. This will also activate manual tuning mode. Preset Tuning Using the remote, up to 30 stations may be stored in the AVR 135�s memory for easy recall using the front panel controls or the remote. To enter a station into the memory, first tune the station using the steps outlined above. Then: 1. Press the Memory Button 34 on the remote. Two underscore lines will appear at the far right side of the Upper Display Line �. 2. Within five seconds, press the Numeric Keys r corresponding to the location where you wish to store this station�s frequency. Once entered, the preset number will appear in the Upper Display Line �. 3. Repeat the process after tuning any additional stations to be preset. Recalling Preset Stations � To manually select a station previously entered in the preset memory, press the Numeric Keys r that correspond to the desired station�s memory location. � To manually tune through the list of stored preset stations one by one, press the Preset Stations Selector Buttons $ 32 on the front panel or remote. NOTES: � The digital outputs are active only when a digital signal is present, and they do not convert an analog input to a digital signal, or change the format of the digital signal. In addition, the digital recorder must be compatible with the output signal. For example, the PCM digital input from a CD player may be recorded on a CD-R or MiniDisc, but Dolby Digital or DTS signals may not. � Please make certain that you are aware of any copyright restrictions on any material you copy.

Press the ¤ Button n until the onscreen � cursor is next to the CHANNEL ADJUST line. Press the Set Button p to activate the CHANNEL ADJUST menu. Once the menu appears on your video screen, first use the �/¤ Buttons n to move the on-screen � cursor so that it is next to the TEST TONE line. Press the � / � Buttons o so that OFF appears. This will turn off the test tone and allow you to use your external test disc or other source material as the reference. Then, use the �/¤ Buttons n to select the channels to be adjusted. At each channel position, use the � / � Buttons o to change the output level. Remember, the goal is to have the output level at each channel be equal when heard at the listening position. Regardless of the method used to adjust the output levels, whether the test tone or an external source is used, remember that when the AVR is configured for 6.1 operation with only a single surround back speaker, you will still have an output adjustment for both a surround back left and surround back right speaker location even though there is only one speaker. This is not a duplicate adjustment. Rather, it is needed so that the proper balance is achieved for 7.1-channel processing modes when the discrete surround back channels are mixed to a single output. If you wish to reset all the levels to their original factory default of 0dB offset, press the �/¤ Buttons n so that the on-screen cursor is next to the CHANNEL RESET line and press the � / � Buttons o so that the word ON appears. After the levels are reset, resume the procedure outlined above to reset the levels to the desired settings. When all n adjustments are done, press the / Buttons

Output Level Trim Adjustment
Normal output level adjustment for the AVR 135 is established using the test tone, as outlined on pages 20�21. In some cases, however, it may be desirable to adjust the output levels using program material such as a test disc, or a selection you are familiar with. Additionally, the output level for the subwoofer can only be adjusted using this procedure. To adjust the output levels using program material, first set the reference volume for the front left and front right channels using the Volume Control � 38 . If you are using a disc with test signals or an external signal generator as the source from which to trim the output levels, you may use a handheld SPL meter to guide you to the correct SPL levels. Set the meter to the C-Weighting Slow scale, and adjust the volume until the meter reads 75dB. Once the reference level has been set, press the Channel Select Button m and FRONT L LEVEL will appear in the Lower Display Line ¯. To change the level, first press the Set Button p, and then use the �/¤ Buttons n to raise or lower the level. DO NOT use the volume control, as this will alter the reference setting. Once the change has been made, press the Set Button p and then press the �/¤ Buttons n to select the next output channel location that you wish to adjust. To adjust the subwoofer level, press the �/¤ Buttons n until WOOFER LEVEL appears in the Lower Display Line ¯. Repeat the procedure as needed until all channels requiring adjustment have been set. When all adjustments have been made and no further adjustments are made for five seconds, the AVR 135 will return to normal operation. The channel output for any input may also be adjusted using the full-OSD on-screen menu system. First, set the volume to a comfortable listening level using the Volume Control � 38 . Then, press the OSD

Recording
In normal operation, the audio or video source selected for listening through the AVR 135 is sent to the record outputs. This means that any program you are watching or listening to may be recorded simply by placing machines connected to the Tape Outputs £ or Video 1 Audio/Video and S-Video Outputs dj in the Record mode. When a digital audio recorder is connected to the Digital Audio Outputs ��, you are able to record the digital signal using a CD-R, MiniDisc or other digital recording system.

to move the on-screen � cursor so that it is next to BACK TO MASTER MENU and then press the Set Button p if you wish to go back to the main menu to make other adjustments. If you have no other adjustments to make, press the OSD Button v to exit the menu system. NOTE: The output levels may be separately trimmed for each digital and analog surround mode. If you wish to have different trim levels for a specific mode, select that mode and then follow the instructions in the steps shown earlier. Memory Backup This product is equipped with a memory backup system that preserves the system configuration information and tuner presets if the unit is accidentally unplugged or subjected to a power outage. This memory will last for approximately four weeks, after which time all information must be reentered.
