6.CONNECTIONS AND CABLES

6.1Balanced vs. Unbalanced Audio Connections

Balanced signal connections are preferred in pro audio applications because of their improved immunity to induced hum and noise. A properly shielded and wired balanced input stage on any product will by design reject most unwanted noise picked up by the cable as well as minimize ground loop problems. Therefore it is always advantageous to use balanced connections when running signal more than ten or fifteen feet, although particularly noisy environments (high RFI, EMI, etc.) may require that even short cabling be balanced.

Unbalanced connections are used mostly for short distance, high level signals (0dBu nominal). Most exter- nal EMI noise pick-up will be masked under the noise floor of the signal, assuming there is little or no gain fol- lowing the unbalanced signal. If a gain stage does follow a signal, or if externally sourced noise persists, use bal- anced connectors. The main advantage of unbalanced con- nectors is cost, as an unbalanced (tip-sleeve) plug costs less and is easier to wire than a balanced (TRS) plug.

6.2 Inputs and Outputs

Your MQX equalizer is provided with three dif- ferent connector types. 1/4" TRS (tip-ring-sleeve) phone jacks, three pin XLR connectors, and screw terminals will allow interfacing to most professional audio products. Ashly TRS balanced connections use the tip as (+) and the ring as (-) signal, with sleeve used for ground. Ashly XLR connectors use pin 2 (+) and pin 3 (-) with pin 1 ground. Inputs are active balanced using precision 1% metal film resistors. Outputs are "pseudo-balanced", which means they have balanced impedance with a single- ended signal source, and can be wired balanced or unbal- anced. When possible, we recommend balanced connections between all components in your system.

If inputs are used unbalanced, the signal should be on the (+) connection and the (-) connection must be tied to ground, or signal loss will result. While a mono phone plug used as an unbalanced connection will auto- matically ground the (-) ring of the jack, XLR and screw terminals will not automatically do this so attention must be given to proper wiring.
