Stereo Linking of Inputs 1 and 2

Stereo linking allows Inputs 1 and 2 to be controlled as a single, stereo input. This is useful when

stereo microphones or stereo line level signals are used with the 302. Stereo linking allows the user to

control the overall signal of both inputs with a single fader.

There are two modes of operation for stereo linking, X/Y link and MS stereo. Stereo linking is

activated in the Setup Menu.

X/Y Stereo Link

Inputs 1 and 2 can be linked as a stereo pair to simplify control when using stereo microphones.

X/Y stereo linking is set in the Setup Menu. When in X/Y stereo link operation, Inputs 1 and 2

Pan switches continue to control the signal routing for each respective channel. Channel 2’s Fader

controls the overall level of the stereo pair. Input 1 and 2’s Gain (trim) pots and High-Pass Filters

continue to act independently of each other. When linked, Channel 1 and 2’s Input Limiters are also

linked.

MS Stereo Linking

When MS stereo linking is selected in the Setup Menu, Inputs 1 and 2 are linked as an MS (Mid-

Side) stereo pair. MS is a popular stereo conﬁguration because of its good spatial placement, mono-

compatibility, and surround compatibility.

The 302’s MS matrix uses Input 1 for the Mid signal and Input 2 for the Side signal. Input 2’s Fader

controls the overall gain of the MS stereo pair. Input 1’s Fader and both Input 1 and 2’s Pan switches

are disabled. Input 1 and 2’s Gain (trim) pots and High-Pass Filters continue to act independently of

each other. The Gain control for Inputs 1 and 2 are used to vary the Mid and Side levels respectively.

Using the Input 2 Gain is an effective way to control the stereo spread.

Inputs 4 & 5

When additional inputs are needed, such as when multiple wireless receivers are

used, the Return connector can be assigned to act as the input connector for Channels 4 and 5. This

functionality is set in the Setup Menu. See Setup Menu.

Several options are available for Inputs 4 and 5. Either or both of the inputs can be sent to the left,

right, or left and right output bus. Control the input sensitivity of Inputs 4 and 5 with the RTN L

(CH4*) and RTN R (CH5*) Trim controls adjacent to the RTN (Input 4/5*) 3.5-mm Female connector.

The RTN (Input 4 and 5) Input is an unbalanced stereo input that is suitable for tape or line level devices

only. There are no microphone preamps on Inputs 4 and 5.

To indicate that the Return connector is now used for Inputs 4 and 5, the 4/5 Channel Enabled LED

(on the output panel) illuminates.
