Facilidade de uso


pressing this button mutes all sound from the amplifier and allows a tuner connected to the TUNER / LINE socket to operate for silent tuning. Release the button and you are back in action again. ABM/RPM-1 MAG 300 Electric Blue 180 Front/Rear Panel Facilities ABM, RPM-1, MAG 300 & ELECTRIC BLUE 180 300 / 500 WATT ABM HEAD / COMBO 900 WATT ABM HEAD / COMBO I o 5 4 3 2 1 0 10 9 8 7 6 58 52 47 42 39 35 150 120 95 75 65 RPM1 RACK-MOUNT PREAMP TUNER / LINE OUT This output socket provides a line level signal that can be used either for a permanent connection to a tuner or a line output to slave up to other power amplifiers. (ABM/RPM-1 users - Please note that if this socket is used as a slave output to other power amplifiers that the MUTE button will not mute the signal to the external power amplifiers.) SUB OUT (ABM/RPM-1 only) This output socket provides a Low Pass filtered output for connection to a power amplifier driving a sub unit for additional extra-low bottom end.This may also be used to drive other power amplifiers to provide additional low bottom end to the system.The Low Pass filter is fixed at 160Hz. OUTPUT LEVEL The OUTPUT control adjusts the overall level of the amplifier. Adjust this for your preferred overall stage playing volume. REAR PANEL FACILITIES LINE INPUT (ABM/RPM-1 only) The rear panel has a Line Input socket for connection of other signal sources into the system.This can be used for plugging a CD,Tape or MiniDisc player into the amplifier for practising or rehearsing or for connection of a second preamp into the system. EFFECTS SEND / RETURN (rear panel on ABM/RPM-1 & front panel on MAG 300 & Electric Blue 180) A serial effects loop is provided at a level of 0dB.The Effects Send and Return sockets for this are on the rear panel of the ABM/RPM-1 and front panel of the MAG 300 and Electric Blue 180 below the D.I. socket. The EFFECTS SEND socket can also be used as a Line Out socket if required.The signal path through the preamp is only broken when a jack plug is inserted into the EFFECTS RETURN socket.The EFFECTS SEND is situated after the EQ,Valve section and Sub Bass Processor. FOOTSWITCH SOCKETS (ABM/RPM-1) Two stereo jack sockets marked SUB/VALVE and EQ/SHAPE are provided for connection of 2-way push on/push off type foot switches.The SUB footswitch mutes the Sub Harmonics when closed. For this to operate the Sub Harmonics must already be activated with the front panel push switch. For all other footswitches to operate, the corresponding front panel push buttons must be in their OUT position. CROSSOVER AND OUTPUTS (Rack Preamp RPM1 only) The BASS MAGNIFIER RACK PREAMP RPM1 has a built in high precision CROSSOVER with separate jack socket outputs for the HIGH PASS and LOW PASS signals. Crossover frequency is adjustable from 35Hz to 160Hz with a level control for the LOW PASS output to adjust the balance between LOW and HIGH outputs signals.There is also a FULL RANGE jack line output provided.This section is provided with switched output levels for simplified connection to power amplifiers that require either a 0dB or +4dB signal level.This switches the levels of all three outputs. SPEAKER OUTPUT (except Rack Preamp RPM1) The Speaker Output sockets are also situated on the rear panel of the unit.The ABM provides both jack and speakon connectors.
