APPENDIX-

Balanced connection is recommended for all inputs. The XLR inputs on the DSP-4 are electronically balanced. Balanced input

cables are recommended to minimize noise pick up and prevent ground loops.

If constructing your own cables, refer to the pinout, above, for proper connector wiring.

Unbalanced inputs can be used if required. If unbalanced audio sources are used, the minus (-) and shield terminals should be

connected with a jumper wire. However, it is preferable to use an audio transformer (or other unbalanced-to-balanced “converter”) to

provide a balanced input to the DSP-4.
