Likewise, adjustment of the Volume Stabilization switch will not have any affect. - Page 12 VCR or satellite receiver on your Figure 5 Connection in a Tape Loop Useful if you want the SVS-1B to affect the output of any device connected to your receiver. Simply select the desired input and then monitor the “tape” to hear the SVS-1B.
