[. . . ] A polarized plug has two blades with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. [. . . ] In general, low frequencies will be redirected from the outputs with the highest crossover setting to the outputs with the lowest crossover setting. Remaining low frequencies below the lowest crossover setting will be redirected to the SUBWOOFER L/R outputs. If the lowest crossover setting is FULL, no low frequencies will be redirected to the SUBWOOFER L/R outputs. The CUSTOM SETUP menu can be used to configure the MAIN AUDIO OUTPUTS for a custom speaker system. For a Synthesis 7channel setup that requires THX-certified loud speakers, use the SYNTHESIS 7CH SETUP menu (see page 3-24).

The curves show the frequency response of each crossover setting. From left to right, the curves represent crossover settings from 30Hz to 120Hz. Highpass Filter The highpass filter attenuates low frequencies at 24dB per octave. The curves show the frequency response of each crossover setting. From left to right, the curves represent crossover settings from 30Hz to 120Hz. This graph does not illustrate the THX 80Hz setting, which is 12dB per octave. 3-19 The SETUP Menu MAIN MENU MODE ADJUST AUDIO CONTROLS SETUP SETUP INPUTS SPEAKERS REAR PANEL CONFIG DISPLAYS VOLUME CONTROLS TRIGGERS LOCK OPTIONS SPEAKER SETUP CUSTOM SETUP SYNTHESIS 7CH SETUP SPEAKER DISTANCES LEVELS CALIBRATION R SR RR 80Hz 80Hz 80Hz JBL CUSTOM SETUP FRONT L/R CENTER SIDE L/R REAR L/R SUB L/R SUB XOVER LFE 80Hz 80Hz 80Hz 80Hz MONO 80Hz OFF FRONT L/R SPEAKERS FULL 30Hz 40Hz 50Hz 60Hz 70Hz 80Hz THX 80Hz 90Hz 100Hz 110Hz 120Hz CENTER SPEAKER FULL 30Hz 40Hz 50Hz 60Hz 70Hz 80Hz THX 80Hz 90Hz 100Hz 110Hz 120Hz NONE C 80Hz M SUB 80Hz 80Hz L SL RL 80Hz 80Hz CUSTOM SETUP (continued) SETUP SPEAKERS CUSTOM SETUP CENTER (FULL, 30Hz to 120Hz, THX 80Hz, NONE) FRONT L/R (FULL, 30Hz to 120Hz, THX 80Hz) The FRONT L/R parameter sets the crossover setting for the MAIN AUDIO OUTPUTS labelled FRONT L/R. When set to FULL, the unit sends a full-range audio signal to the FRONT L/R outputs. When set to a numerical crossover setting, the unit activates a crossover at the selected frequency. Choose the setting that matches the lowest crossover setting in the system. See pages 3-18 and 3-19 for more information about crossover settings. The SUB L/R parameter determines the configuration of the MAIN AUDIO OUTPUTS labelled SUBWOOFER L/R. When set to MONO, the front left and right, center, side left and right, and rear left and right channels are combined and sent to the SUBWOOFER L/R outputs. This setting is recommended for all Synthesis systems, regardless of the number of subwoofers being used. When set to STEREO, low frequencies from the front left, center, side left, and rear left channels are combined and sent to the SUBWOOFER L output. Low frequencies from the front right, center, side right, and rear right are combined and set to the SUBWOOFER R output. 3-22 SDP-40 MAIN MENU MODE ADJUST AUDIO CONTROLS SETUP SETUP INPUTS SPEAKERS REAR PANEL CONFIG DISPLAYS VOLUME CONTROLS TRIGGERS LOCK OPTIONS SPEAKER SETUP CUSTOM SETUP SYNTHESIS 7CH SETUP SPEAKER DISTANCES LEVELS CALIBRATION R SR RR 80Hz 80Hz 80Hz The SETUP Menu CUSTOM SETUP FRONT L/R CENTER SIDE L/R REAR L/R SUB L/R SUB XOVER LFE OFF 80Hz 80Hz 80Hz 80Hz MONO 80Hz C 80Hz M SUB 80Hz 80Hz L SL RL 80Hz 80Hz LFE (ON, OFF) LFE (Low Frequency Effects) activates and deactivates the MAIN AUDIO OUTPUT labelled LFE.
