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.
