The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying this product. GROUNDING INSTRUCTIONS This product must be grounded (earthed). If it should malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This product is equipped with a supply cord having an equipment grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with the local codes and ordinances. DANGER -Improper connection of the equipment grounding conductor can result in a risk of electric shock. Check with a qualified electrician or serviceman if you are in doubt as to whether the product is properly grounded. Do not modify the plug provided with the product – if it will not fit the outlet, have a proper outlet fitted. The wires in this mains cord are coloured in accordance with the following code: Green & Yellow - Earth Blue - Neutral Brown - Live CE MARK FOR EUROPEAN HARMONISED STANDARDS The CE mark which is attached to these products means it conforms to EMC Directive (89/69/EEC), CE mark Directive (93/68/EEC) and Low Voltage Directive (72/23/EEC). This is a NO COMPROMISE design using the best parts available wherever possible. Some examples of this are as follows: • Gold plated jack sockets for reliability and long life. • Full metal XLR sockets for strength and their positive latching facility. • Powerful output stages for extra headroom (rated in English RMS real power and not MUSIC or PEAK power as these can claim to be 2 or 3 times the actual real power of the amplifier). • Doubling up of the cooling fans for reliability and reduced fan noise (2 fans can run at half the speed to provide the same cooling capacity and as a consequence generate only half the noise of one fan running at twice the speed). • Speed controlled fan drive circuit. Again this reduces the amount of fan noise as the fans run slow when the unit is cool and increase in speed with output power demands. • Powerful TOROIDAL mains transformer.This is more expensive than a laminated stack transformer but has better regulation, i.e., provides more power on demand without sagging out and also has a minimal external magnetic field which means that single coil pick up basses are less likely to pick up mains hum from the amplifier. • FET input circuit to the preamp for ‘Warmth’ even when using the CLEAN input mix setting. • D.C. heaters for the TUBE section for low noise operation. • Switch on delay for silent power up. • Thermal trip for output protection. • Relay switched speaker output lines for silent power down. • Sub Bass output and Sub Harmonics facility for really serious bottom end. Everything possible has been done to make this a reliable, top of the range, minimum service, high quality, long lasting powerful bass amplifier. We know you will appreciate the effort that has been put into the design and manufacture of this unit and you will be rewarded in your choice of bass amplifier by long life and reliability. Front Panel Facilities ABM, RPM-1, MAG 300 & ELECTRIC BLUE 180 INPUTS On the MAG 300 and Electric Blue 180, there are two choices of instrument input, these are marked HIGH and LOW.The HIGH input is high sensitivity and also high impedance to suit the output from PASSIVE basses.The LOW input is low sensitivity and lower impedance to suit the output from ACTIVE basses.The ABM has a single instrument input provided, linked to a PASSIVE/ACTIVE selector switch (switch out=PASSIVE, switch in=ACTIVE). INPUT CONTROL The INPUT control sets the signal level through the preamp in conjunction with the INPUT LEVEL VU Meter (Electric Blue 180 uses a LED display).This is adjusted to give a reading of 0VU on the meter (yellow LED on Electric Blue 180) for average playing dynamics with occasional peaks into the red (red LED on Electric Blue 180) region. Please note that this setting may require re-adjustment after modification of the EQ controls. PUSH FLAT / SHAPE (ABM/RPM-1 only) With this button in its OUT position a fixed E.Q. is superimposed on the preamp to give a bright but punchy character to the sound. Pushing this button IN returns the preamp to a Flat frequency response. This function may also be controlled from a footswitch. For the footswitch to operate, this button must be in its OUT position. VALVE DRIVE (ABM/RPM-1 only) This routes the signal either through a clean Solid State amplification section (control on zero) or through a Dual Triode Tube amplification/overdrive section to add either tonal character, i.e. warmth with the control set at 9 o’clock, a slight edge in the sound at 12 o’clock, through to an increasing degree of Tube distortion/overdrive as the control is advanced to maximum...
