A ground lift switch is provided which opens pin 1 (shield) on the direct output to prevent ground loops. Use the position that results in a minimum of noise.

The output level is nominal line level (typ. between -10 and -30 dB), pin 2 hot. This output is fully protected from the effects of phantom power provided by the mixing console and does not require phantom power to operate.

Output Jacks -

The 250 series amplifiers feature standard 1/4” speaker jacks, one for the internal speaker (combo models) and one for an external speaker cabinet. Minimum recommended load impedance is 4 ohms, though loads as low as 2 ohms may be used provided adequate ventilation for the heatsink area is provided. This may require an external fan in some climates. The 500 series amplifiers feature the same two 1/4” jacks plus a Neutrik “Speakon” NL-4 connector. The “Speakon” is wired using pins 1+ and 1-, pins 2+ and 2- are not connected.

Speakers Offered -

The 250 series amplifiers (combo versions) are currently offered as a 2x10” + horn, 1 x 12” + horn and 1 x 15” + horn in an equivalent “XB Series” tuned cabinet. Power handling capacity of the drivers is carefully matched to the amplifiers to insure a long, trouble free life.

General Information -

Power is supplied to the amplifier through an IEC type detachable cord set with a mains connector, fuse holder and internationally rated 115/230 Volts - 50/50 Hz toroidal power transformer. For our international touring players, an external mains line voltage switch is provided, with a fuse size chart printed on the rear of the unit denoting the power supply configuration and fuse size that the unit has been rated for. International IEC type cordsets are available for a variety of international power supply sockets.

Common sense (as well as the law) dictates that you do not operate the unit where it will be exposed to moisture or rain, excessive ambient heat (over 110 degrees F / 40 degrees C) or without a properly grounded A.C. power source. Never remove the ground pin from the A.C. power connector.

Ventilation is required to keep this amplifier from overheating. Do not block air flow over heatsinks at the rear of the unit.
