[. . . ] POWER AMPLIFIER Owner's Manual E · Explanation of Graphical Symbols CAUTIO N RISK OF ELECTRIC SHOCK DO NOT OPEN The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product. CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER (OR BACK). REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. The above warning is located on the top of the unit IMPORTANT SAFETY INSTRUCTIONS Read these instructions. 8 Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. [. . . ] · The unit offers three operating modes: STEREO (where Channels A and B operate independently), PARALLEL (where the unit outputs a mono source through twin amplifier systems), and BRIDGE (where the unit operates as a single high-power amp). · Each channel is equipped with an independent OFF/LOW CUT/SUBWOOFER switch--where LOW CUT engages a high-pass filter, and SUBWOOFER engages a low-pass filter. With LOW CUT or SUBWOOFER selected, you can adjust the cutoff frequency from 25 to 150 Hz. · The PROTECTION indicator lights up--and sound output is automatically muted--whenever the unit's protective circuitry is operating. This Owner's Manual covers the four models: P7000S, P5000S, P3500S and P2500S power amplifiers. Please read through this manual carefully before beginning use, so that you will be able to take full advantage of the amplifier's superlative features and enjoy trouble-free operation for years to come. After reading through the manual, please store it in a safe place.

You use the FILTER switch to select the filter, as follows. 2 ON/OFF switch If you set this switch ON, the amplifier adds low-frequency compensation so as to enhance speaker output. The results (the actual change in the low-frequency balance) will vary according to the speaker type. Note that this switch is effective only if the FILTER switch is set to OFF. NOTE: This feature provides improved frequency reponse on speakers such as the YAMAHA S112 and S115. SUB OFF WOOFER LOW CUT OFF . . . . . . . . . . . . . . . . . . . . . . The amplifier outputs the frequencies that are lower than the cutoff set by the FREQUENCY adjustment knob. You can use this setting to filter out unneeded low or subsonic frequencies.
