User manual DOD R410

[. . . ] Discard the mains plug at a suitable disposal facility. NEVER UNDER ANY CIRCUMSTANCES SHOULD YOU INSERT A DAMAGED OR CUT MAINS PLUG INTO A 13 AMP POWER SOCKET. Do not use the mains plug without the fuse cover in place. Replacement fuse covers can be obtained from your local retailer. [. . . ] The x10 function allows you to change the range of each notch (see the graph below). These filters are "Disabled" by setting the depth control to the top (0dB cut). These filters are used primarily for eliminating feedback or hum from the P. A. or monitor systems. Notch 1 40Hz 400Hz 4KHz 20Hz 200Hz 2KHz 20KHz Notch 2 standard range x10 ranges 6. Limiter - The limiter function features Automatic Variable Ratio LimitingTM. AVR Limiting behaves as a mild compressor with a soft knee at low threshold settings, and a hard knee limiter at higher threshold settings. This allows the limiter to function as a mild compressor or as a limiter for speaker protection. The fast/slow speed switch affects both the attack and release time. This gives enough variety for most situations. The gain reduction meter displays the amount of gain reduction due to limiting. Low Cut - A selectable low cut (high pass) filter that may be switched in or out and has selectable rolloff frequency of 40 or 80Hz.

WARNING: SHOCK HAZARD-DO NOT OPEN AVIS: RISQUE DE CHOC ÉLECTRIQUE-NE PAS OUVRIR SALT LAKE CITY, UTAH 5 1. Balanced Output -Accepts a female XLR plug (see section on installation for wiring). Balanced/Unbalanced Output - Accepts a 1/4" tip-ringsleeve balanced or 1/4" unbalanced tip-sleeve plug (see section on installation for wiring connections). Output impedance is 20k for the unbalanced connection and 40k for balanced. Balanced Thru Output - Accepts a female XLR plug (see section on installation for wiring connections). This output is hardwired to the input allowing the signal to be split off to another destination. Balanced output is possible only with a balanced input signal. Balanced/Unbalanced Thru Output - Accepts a 1/4" tipring-sleeve balanced phone plug or a 1/4" unbalanced tip-sleeve plug (see section on installation for wiring connections). Balanced Input - Accepts a male XLR plug (see section on installation for wiring connections). [. . . ] Input Impedance: 20k unbalanced, 40k balanced. Maximum Input Level: +21dBu (ref; 0. 775 VRMS). Output Impedance: 51 unbalanced, 102 balanced. Limiter Attack Time: Slow 18ms Fast 2ms. [. . . ]
