Patch Panel; E-Zinterface; Mic Input - Mackie SR40.8 Owner's Manual

PATCH PANEL

At the risk of stating the obvious, this is
where you plug everything in: microphones,
instruments, effects, headphones, and the ulti-
mate destination for your sound: PA system,
tape recorder and the like.
SR40•8, you can patch anything almost any-
where, with nary a care. Here's why:
• Every input and output is balanced (except
single-jack inserts, phones and RCA jacks),
using close-tolerance components to
ensure noise-free performance.
• Every input and output will also accept
unbalanced lines (except floating-ring
cables into XLR inputs — just tie the
cable's ring to the shield first).
• Every input is designed to accept virtually
any output impedance.
• The XLR outputs can deliver 28dBu into a
600 ohm load.
• All the other outputs can deliver 22dBu
into a 600 ohm load.
• All the outputs are polarity-correct with
the inputs.

MIC INPUT

Point Before: Balanced microphone-level
cable with male XLR connector (pin 2 = hot,
pin 3 = cold, pin 1 = shield).
Point After: Channel
The female XLR input can accept almost
any type of microphone — dynamic, con-
denser, ribbon or tube condenser. +48 PH
(phantom power)
nel. Radio frequency interference (RFI) is
eliminated by means of close-tolerance bal-
anced circuitry, input filtering and the
SR40•8's steel chassis. Mic-level signals can be
boosted by as much as 60dB.
Do not use this input simultaneously with
its associated LINE IN
and engage MUTE
moving mic cables. Do not insert unbalanced
single-ended cables (signal on pin 2, pin 3
open) unless pin 3 is first tied to ground (pin
1), and the +48 PH
