Input and output connections

1. XLR inputs

On the rear of the Pictor are six XLR inputs, two on each side. As you are looking at the rear panel, the left three XLR in-

puts are for the right channel, the right three inputs are for the left channel. Underneath each jack is the corresponding

input number. Use of XLR connections is recommended for the best possible audio quality. To remove an XLR plug, push

on the tab above the jack and pull the plug out.

IMPORTANT NOTE: To preserve true dual-mono operation, the Pictor uses a symmetrical circuit layout. This configura-

tion requires that the amplifier's back panel connections be laid out a little differently from those on most preamps. For

example, the left-channel connection for Input 1 is on the right side of the back panel, and the right-channel connection is

at the left side. Connecting the cables in the usual side-by-side fashion will result in an incorrect installation and the mix-

ing of sounds from different source devices.

2. RCA inputs

These unbalanced inputs are provided as a convenience for use with unbalanced signal sources. Whenever possible, we

recommend using XLR connections instead. Connecting to an unbalanced source is handled in the same way an XLR bal-

anced source. To remove an RCA plug, grasp the plug and pull it out. Do not pull on the cable.
