[. . . ] Do not defeat the safety purpose of the polarized or grounding-type plug. When the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. Use only attachments/accessories specified by the manufacturer. [. . . ] Set this switch to "115" for nominal line voltages of 110-120 VAC. Set this switch to "230" for nominal line voltages of 220-240 VAC. Make sure that the appropriate fuse is installed when changing voltage selections. For 230 volt operation, use a T 1A L 250V fuse. 4. 2. 3. Output Barrier Strip. The output barrier strip provides connections for the output of the amplifier. When the unit is shipped from the factory, the distribution autoformer is not hooked up and signal is only present at the 4 ohm output. To use the 8, 70V, or 100V outputs, the jumper wire must be connected from the 4 output terminal to the autoformer input terminal. NOTE: From the factory, the D60EQ has an 18dB/octave 180Hz high-pass filter enabled. This high-pass filter must remain enabled whenever an autoformer output is being used (8, 70V, or 100V). The high-pass filter should be disabled only when using the `direct' 4 output (see Options & Accessories on page 8). The input barrier strip provides connections for the balanced input to the amplifier. The bottom three terminals on this barrier strip are unused. 5. 7 OPTIONS & ACCESSORIES CAUTION: Modifications must be performed by qualified service professionals. AC power must be disconnected, and the top panel must be removed before performing any of the following modifications to the D60EQ. FILTER IN OUT High-Pass Filter A jumper strap labelled `FILTER' on the amplifier circuit board enables or disables an 18dB/octave 180Hz high-pass filter. When the strap is in the "IN" (up) position, the filter is enabled. [. . . ] The remedies set forth herein shall be the purchaser's sole and exclusive remedies with respect to any defective product.
