English Controls and Functions  POWER indicator Lights when the power switch () is set to on.  FRONT LED DISABLE switch Selects turning on or off the FRONT LED at the left of the unit's front grille. The LED will light when this switch is set to off (/). Turn this switch on (0) when you want to turn off the LED. NOTE When the limiter for protecting the amplifier operates, the LED will light brighter than usual in proportion to the amount of attenuation (3dB or higher).  MIC/LINE switch (DXR series) Set this switch to MIC or LINE for INPUT1 jack, depending on the level of the input signal. For low-level signals (such as microphones), set the switch to the MIC position. For high level signals (such as mixer), set the switch to the LINE position. D-CONTOUR switch (DXR series) Selects one of the D-CONTOUR (Dynamic CONTOUR) presets. The FOH/MAIN setting will boost the high and low frequency components so that the frequency response will become suitable for a main speaker. The MONITOR setting also suppresses the low range, which could otherwise tend to be boomy if the speaker is set directly on the floor or used along with a main speaker. With the FOH/MAIN or MONITOR setting, the D-CONTOUR function is enabled and controls the boost and attenuation amounts dynamically in relation to the sound volume. When this switch is set to OFF, a generic frequency response setting will be used and the D-CONTOUR function will be turned off.  HPF switch (DXR series) Specifies the HPF's cut-off frequency. If the switch is set to 120Hz or 100Hz, the high-pass filter will cut the frequency components below that threshold. If you plan to use your DXR without a subwoofer, set this switch to OFF. If you plan to use the DXR along with a subwoofer, we recommend that you set this switch to 120Hz or 100Hz. ! LINK OUT jack (DXR series) This XLR jack outputs signals (routed from each INPUT jack) to a connected DXR series speaker. Connect this jack to the INPUT 1 (XLR) jack on the linked DXR series speaker. Signals at the LINK OUT jack are line-level. Set the MIC/LINE switch on the linked DXR series speaker to LINE. For stereo signals, set the LEVEL control on the linked DXR to the 12 o'clock position to balance the levels between two DXRs.  LINK MODE switch (DXR series) Enables you to select whether the mixed signal (on the original DXR) will be played in stereo or monaural on the original and linked DXRs. The following signals are mixed and output according to the switch setting. LINK MODE Input of the original DXR Output of the original DXR Output of the linked DXR STEREO INPUT1 INPUT2/3 L R   -  -  MONO INPUT2/3 INPUT1 LR   NOTE If you use only a single, stand-alone DXR, set this switch to MONO (/). If you set the switch to STEREO (0), audio signals input at the R channel of INPUT 2/3 will not be output.  POLARITY switch (DXS series) Selects the subwoofer polarity. In most cases, for example if the subwoofer and DXR series speaker are installed on a speaker pole, set this switch to NORM (NORMAL). However, an INVT (INVERTED) setting may improve low-range response, depending on the type and location of the speaker system. Try both settings and select the one that produces the best low-end sound.  D-XSUB switch (DXS series) Selects one of the D-XSUB presets. The BOOST setting boosts the low frequency range to enhance and punch-up the frequency response. The XTENDED LF extends the bottom of the low frequency range to enhance broad lowrange frequency response. With the BOOST or XTENDED LF setting, the D-XSUB function is enabled and controls the boost amount dynamically in relation to the sound volume. When this is set to OFF, a generic frequency response will be used and the D-XSUB function will be turned off. ? LPF switch (DXS series) Specifies the low-pass filter's cutoff frequency at 120Hz, 100Hz, or 80Hz. The filter will cut the frequency components above the specified threshold. If you are using the DXS along with a DXR, match this frequency to DXR's HPF switch setting. 8 DXR15/DXR12/DXR10/DXR8/DXS15/DXS12 Owner's Manual
