[. . . ] AVERTISSEMENT: Afin de prévenir les risques de décharge électrique ou de feu, n'exposez pas cet appareil à la pluie ou à l'humidité. Avant d'utiliser cet appareil, lisez les avertissements supplémentaires situés dans le guide. Dieses Symbol soll den Anwender vor unisolierten gefährlichen Spannungen innerhalb des Gehäuses warnen, die von Ausreichender Stärke sind, um einen elektrischen Schlag verursachen zu können. Dieses Symbol soll den Benutzer auf wichtige Instruktionen in der Bedienungsanleitung aufmerksam machen, die Handhabung und Wartung des Produkts betreffen. VORSICHT: Um das Risiko eines elektrischen Schlages zu vermeiden, nicht die Abdeckung enfernen. [. . . ] To use these outputs, the jumper between 4 ohm and XFMR must be installed. For 8 ohm speaker systems, connect between the COM terminal and the 8 ohm terminal. For "distributed" speaker systems, 25 volt and 70 volt outputs are provided. This output is provided for direct connection to booster power amplifiers, etc. NOTE: Due to the high gain and frequency response of the UMA Series amplifiers, it is necessary that the input cables be routed away from the output cables to prevent instability. AC OUTLET (UNSWITCHED) (30) Provides AC power for auxiliary equipment with power consumption -- 300 watts maximum. FUSE (31) The fuse is located within the cap of the fuseholder. If the fuse should fail, IT MUST BE REPLACED WITH THE SAME TYPE AND VALUE IN ORDER TO AVOID DAMAGE TO THE EQUIPMENT AND TO PREVENT VOIDING THE WARRANTY. If the amp repeatedly blows fuses, it should be taken to a qualified service center for repair. WARNING: THE FUSE SHOULD ONLY BE REPLACED WHEN THE POWER CORD HAS BEEN DISCONNECTED FROM ITS POWER SOURCE. LINE CORD (120 V PRODUCTS ONLY) (32) For your safety, we have incorporated a three-wire line (mains) cable with proper grounding facilities. If it is necessary to use the equipment without proper grounding facilities, suitable grounding adaptors should be used. Less noise and greatly reduced shock hazard exist when the unit is operated with the proper grounded receptacles. 6 INSTALLING THE RACK-MOUNT EARS This unit can be rack-mounted with an optional rack-mount kit. To attach the rack-mount ears, simply remove the three screws already in the front on either side of the unit and align the ears with the rack-mount flange forward of the unit. Replace the screws and tighten securely, being careful not to overtighten. You may find it desirable to remove the rubber feet from the bottom of the unit in rack-mount installations. Channels 1 and 2 shall have screw terminals and XLR connectors for the Low-Z inputs; screw terminals for the High-Z inputs. Channels 3 and 4 shall have screw terminals for the Low-Z inputs; screw terminals and RCA phono connectors for the High-Z inputs. Channels 1 through 4 shall have 24 volt phantom power for the Low-Z inputs. The Page input shall be transformer balanced (600 ohms) and shall have screw terminals for the input connection. The master section shall include one Master Volume level control, two EQ controls providing 10 dB boost or cut at 100 Hz and 10 kHz, and a "Contour" switch providing 6 dB of boost at 100 Hz and 10 kHz. Mute 1 shall give precedence to the Page input, and it shall override Channels 1 through 4, with a threshold control on the Page input. Mute 2 shall give precedence to Channel 1, and it shall override Channels 2 through 4, with a threshold control on Channel 1. The two mute lines shall have screw terminals for external mute control. The unit shall have a Channel 4 output that provides an RCA phono, non-mutable output of Channel 4. [. . . ] This product should be used only with a cart or stand that is recommended by Peavey Electronics. Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary considerably in susceptibility to noise induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a sufficient time. Government's Occupational Safety and Health Administration (OSHA) has specified the following permissible noise level exposures. [. . . ]
