User manual PIONEER M-AX10

[. . . ] DUAL-DRIVE AMPLIFIER M-AX10 Operating Instructions Congratulations on buying this fine Pioneer product. Please read through these operating instructions so you will know how to operate your model properly. After you have finished reading the instructions, put them away in a safe place for future reference. IMPORTANT NOTICE The serial number for this equipment is located on the rear panel. Please write this serial number on your enclosed warranty card and keep it in a secure area. [. . . ] Be sure to turn the power off before switching between modes. Switching with the power on will activate the warning circuit. The mode illumination light and mode indicator will flash, and the output will be muted. If this happens, you should turn the operation mode switch back to its original position. The flashing will stop, and your M-AX10 will return to normal. ATT HOLD This button is activated only if the OPERATION MODE switch is pointing to SEPARATE. Pressing the ATT HOLD (attenuator hold) button while in separate mode allows whatever attenuation has been set with the ATTENUATOR knob to be retained. Pressing it again will cancel the operation. Note, however, that it is not possible to turn ATT HOLD on and off while the output is muted (eight seconds after switching the power on). ATT THROUGH BEWARE: If this button is used the volume will be heard at maximum level. Pressing the ATT THROUGH button for two seconds or longer causes the sound to be output through the speakers without passing through the attenuator circuit. However, because the mute circuit is activated, there is no sound for five seconds after the button is depressed. The sound will emerge from the speakers five seconds after the ATT THROUGH button is pressed. Pressing the button again will cancel the operation. ILLUMINATION Pressing the ILLUMINATION button once, twice or three times alters the brightness of the panel light, mode illumination light and mode indicator as indicated below. Pressing it a fourth time will return the lights to their initial settings.

Note, however, that this is not possible if the OPERATION MODE switch is set to SEPARATE. ATTENUATOR This knob allows you to adjust the attenuation in 31 stages. In dual and bridge modes it functions as a volume control: 0 dB when turned full right, and - ¥ when turned full left. In Separate mode it functions as an attenuator for adjusting the volume of the high-frequency channel (0 to -15 dB, in 0. 5 dB steps): turning it to the left lowers the volume. MODE ILLUMINATION LIGHT The lamp display changes as illustrated below depending on whether the OPERATION MODE switch is set to BRIDGE, DUAL or SEPARATE. Switching operation modes while the power is on will activate the warning circuit and cause the mode illumination light to flash.
