2.3 Choose Input Wire and Connectors

Crown recommends using pre-built or professionally wired bal anced line (two-conductor plus shield), 22-24 gauge cables and connectors. You should use 3-pin Phoenix-type cable ends at the mixer inputs. Unbalanced line may also be used but may result in noise over long cable runs.

Figure 2.3 shows connector pin assignments for balanced wir ing, and Figure 2.4 shows connector pin assignments for unbal anced wiring. The RCA input connectors can also be used for unbalanced inputs.

NOTE: Custom wiring should only be performed by qualiﬁ ed personnel. Class 2 wiring is required.

2.4 Choose Output Wire and Connectors

Use 2-conductor shielded cable and 3-pin Phoenix-type connec tors for Line Output wiring (Figure 2.5).

2.6 Input Routing

In the 28M, any input can be assigned to Output 1, Output 2 or both. The two DIP switches labeled INPUT ROUTING are used (Figure 2.7). Follow the settings printed on the back panel next to the INPUT ROUTING switch. For example, to send input Channel 3 to Output 1 and Output 2, turn on DIP switches 13 and 14.

Figure 2.7 Input Routing DIP Switches

2.7 Phantom Power

To turn on phantom power on all mic inputs, turn on the switch number 7 in the AMP CONFIG DIP switch.

2.8 Priority Muting

A back-panel AMP CONFIG DIP switch (Figure 2.8) can assign Input Ch. 1 or Input Ch. 5 (28M only) as the priority input for each mixer output, which temporarily mutes the remaining inputs. Muting is activated by contact closures.

For example, suppose you conﬁ gured Channel 1 as the priority input. Mic 1 is plugged into Channel 1. A press-to-talk switch in Mic 1 is wired to the Priority connector in the mixer-ampliﬁ er. When you press the mic switch, all other signals are muted so you can make an announcement on Mic 1.

AMP CONFIG

One DIP-switch selection enables Channel 1 as the priority input, which mutes all other inputs to Out 1. In the 28M only, another DIP switch selec tion enables Channel 5 as the priority input, which mutes all other inputs to Out 2. In the 28M only, another set of DIP switches enable Channel 1 as the priority input into both Out 1 and Out 2, effectively muting any input.

To set the mixer for normal mode with no priority:

Set the OUT CONFIG DIP switch as follows: 1 ON 2 OFF 3 OFF 4 OFF 5 ON 6 OFF

To give priority to the Channel-1 input to Out 1 only:

Set the OUT CONFIG DIP switch as follows: 1 OFF 2 ON 3 OFF 4 OFF

Also, wire a SPST switch to the PRIORITY connector between COM and CH 1 OUT 1. Close the switch when you want the Channel-1 input to mute all other inputs feeding Out 1.

To give priority to the Channel-5 input to Out 2 only:

Set the OUT CONFIG DIP switch as follows: 5 OFF 6 ON

Also, wire a SPST switch to the PRIORITY connector between COM and CH 5 Out 2. Close the switch when you want the Channel-5 input to mute all other inputs feeding Out 2.

To give priority to the Channel-1 input to Out 1 and Out 2:

Set the OUT CONFIG DIP switch as follows: 1 OFF 2 ON 3 ON 4 ON

Also, wire a SPST switch to the PRIORITY connector between COM and CH1 Out 1. Close the switch when you want the Channel-1 input to mute all other inputs feeding Out 1 and Out 2.

Note: The routing conﬁ guration is extremely versatile. Many conﬁ gurations for additional applications not highlighted in this document can be created by examining the signal ﬂ ow in the block diagram on page 13.

2.9 Powering Up

1. Turn off any equipment connected to the Line Out connectors.

2. Plug the mixer’s power cord into a 3-wire grounded AC outlet.

3. Turn down the input volume controls.

4. Turn down the master volume control.

5. Turn on the Power switch. The Power indicator should glow.

6. Turn the input volume controls in use about 3/4 up.

7. Have someone talk into a microphone. Turn up the master volume con trol(s) until the output clip LED ﬂ ashes, then turn down the master volume control(s) about 1/4 turn for headroom.

8. Turn on any equipment connected to the Line Out connectors.

9. Turn up the power ampliﬁ er level control until the desired loudness or power level is achieved.

10. Touch up the input levels as needed for equal loudness from each microphone.

If you ever need to make any wiring or installation changes, disconnect the power cord.
