SPR 4


Product Code: spr4
 LaCie d2 Network 2 301504

The SPR 4 bodypack receiver features a rugged die-cast magnesium case. Auto Setup and Environment Scan functions for finding clean frequencies make setting up extremely easy. The 30 MHz bandwidth allows manual selection of 1200 frequencies or the system chooses from preprogrammed frequency preset banks.The SPR 4 provides a backlit display and jog control for ease of use. The display indicates the received signal strength and battery status along with other parameters. Integrated charging contacts allow the optional BP 4000 battery pack to remain inside the receiver whilst being charged on the CU 4000 charger (optional). The BP 4000 will be charged to capacity in only one hour, and can power the SPR 4 for about seven hours.

The only control the artist needs to operate is an ergonomically shaped volume control with integrated on/off switch. Placed in the center of the SPR 4 top panel, the volume control with its clearly discernible detents can be operated intuitively even if it is positioned outside the user's field of vision.

An Individual mix function allows a personalized monitor mix to be set up even where only a small sound system with no separate monitor mixer is available.

To accommodate the individual preferences of users, the SPR 4 has been designed to drive a large number of different types of earphones.
