Guided Tour - Main Section
1: Auxiliary Return Level (orange) - These knobs determine the input level of
signal arriving via the PL 2404’s four stereo Auxiliary returns. The “0” (2 o’clock)
position of each knob indicates unity gain (no level attenuation or boost). Moving
each knob counterclockwise from the “0” position (towards “
∞”) causes the signal
to be attenuated (at the fully counterclockwise position, it is attenuated infinite-
ly—in other words, there is no sound). Moving each knob clockwise from the “0”
position (towards “+10”) causes the signal to be boosted by as much as 10 dB.
For information on how to properly set these, see the sections in this manual
entitled “Setting the Correct Gain Structure” and “Using the Aux Sends and
Returns” (pages 13 and 20).
2: Auxiliary Return Bus switch - These switches determine which of the two
pairs of stereo buses (1/2 or 3/4) the Aux return signal is routed to. When up,
the Return’s signal is routed to the Bus 1/2 faders and then on to the Bus 1/2
jacks as well as (if the Bus “L/R” switch is pressed in—see #10 on page 7) the
Main and Control Room output jacks. When pressed in, the channel’s signal is
instead routed to the Bus 3/4 faders and then on to the Bus 3/4 jacks as well as
(if the Bus “L/R” switch is pressed in) the Main and Control Room output jacks.
If you set the Bus 3/4 faders all the way down (to their “
∞” position), this switch
can be used for selective muting of Aux returns. See the “Busing, Submixing
and Channel Muting” and “Using the Aux Sends and Returns” sections on page
17 and page 20 in this manual.
3: Headphone Level - This knob sets the level of the signal sent to the
headphone jack (see #4 below). WARNING: To avoid possible damage to con-
nected headphones (or, worse yet, to your ears!), always turn this all the way off
(to the fully counterclockwise “0” position) before plugging in a pair of head-
phones—then raise the level slowly while listening. The Headphone Level has
no effect on the final Main output level or on the Control Room output level.
4: Headphone jack - Connect any standard stereo headphones to this jack
(via a 1/4" TRS plug) for private monitoring of the Main output (including all
connected Aux returns). The built-in PL 2404 headphone preamp delivers
120 mw at 33 ohms.
