Appendix B: Connections Owner's Manual Balanced XLR Input Connector The 402VLZ4 mixer has two female XLR inputs. Be sure the cables are wired per AES (Audio Engineering Society) standards: Balanced XLR Input Connector Pin 1 - Shield (Ground) Pin 2 - Positive (+ or hot) Pin 3 - Negative ( - or cold) SHIELD 2 HOT COLD 3 1 1 3 2 SHIELD COLD HOT Balanced XLR Input Connector You can cook up your own adapter for a stereo microphone. "Y" two cables out of a female 1⁄4" TRS jack to two male XLR plugs, one for the right signal and one for the left. Unbalanced 1/4" TS Connector TS stands for Tip-Sleeve, the two connections available on a mono 1/4" cable. This allows for a direct connection to the channel input jacks. Be sure the cables are wired per AES (Audio Engineering Society) standards: Unbalanced 1/4" TS Connector Sleeve - Shield (Ground) Tip - Positive (+ or hot) Balanced 1/4" TRS Connector SLEEVE SLEEVE TIP TRS stands for Tip-Ring-Sleeve, the three c onnections available on a stereo 1/4" cable. This allows for a direct connection to the channel input jacks. Be sure the cables are wired per AES (Audio Engineering Society) standards: Balanced 1/4" TRS Connector Sleeve - Shield (Ground) Tip - Positive (+ or hot) Ring - Negative ( - or cold) RING SLEEVE SLEEVE RINGTIP TIP TIP SLEEVE Unbalanced 1/4" TS Connector TS jacks and plugs are used in many different applications, always unbalanced. The tip is connected to the audio signal and the sleeve to ground (earth). Some examples: • Unbalanced microphones • Electric guitars and electronic instruments TIP • Unbalanced line-level connections RING TIP SLEEVE Unbalanced RCA Connector Balanced 1/4" TRS Connector TRS jacks and plugs are used in several d ifferent applications: • Balanced mono circuits. When wired as a balanced connector, a 1⁄4" TRS jack or plug is connected tip to signal high (hot), ring to signal low (cold), and sleeve to ground (earth). RCA-type plugs (also known as phono plugs) and jacks are often used in home stereo and video equipment and in many other applications. RCA plugs are unbalanced. Connect the signal to the center post and the ground (earth) or shield to the surrounding "basket." Be sure the cables are wired per AES (Audio Engineering Society) standards: • Stereo headphones, and rarely, Unbalanced RCA Connector stereo microphones and stereo line connections. When wired for stereo, a 1⁄4" TRS jack or plug is connected tip to left, ring to right and sleeve to ground (earth). VLZ4 mixers do not directly accept 1-plug-type stereo microphones.
