NOTES
1. Relay contact resistance degrades rapidly with increasing switched power. For maximum relay life (typically 20 x 106 operations) Audio Precision recommends limiting the maximum switched signal power to 5 Watts or 200 mA.
2. Measured between any two selectable channels into the specified load impedance. SWR-2122P (patch point switcher) crosstalk from the interrupted input to output is typically 70 dB to 20 kHz.
Mounting
All switchers occupy one rack unit of height (1.75 inches). They are provided with bottom feet for table top use. They may be rack mounted with an optional rack mount adapter available from Audio Precision (order number RAK-212). These adapters allow either conventional flush front mounting or set-back mounting to prevent the front connectors from protruding from the rack.
For further information, including DIP switch settings, see the Switchers Setup and Installation Guide, 8211.0023.
