1. POWER SWITCH

Use this switch to power unit ON or OFF. The integrated LED will light when the unit is ON. Before turning on this unit, verify connection to the proper voltage AC source, check all connections and turn down the level controls of equipment connected to the outputs.

2. MODE DISPLAY LED

The corresponding LED will light green to indicate whether the SD-2418 is set to Single Mode 1-8 (stereo) or Dual Mode 2-4 (stereo). In Single Mode, the signal input into Ch A is distributed to outputs 1 through 8. In Dual Mode, the signal input into Ch A is distributed to outputs 1 through 4 and a signal input into Ch B is distributed to outputs 5 through 8.

3. CHANNEL A SIGNAL LED

This LED lights green when an audio signal is detected at the input of Channel A. The LED will light red when the input signal is too high and causes clipping. If the LED is blinking red, turn down the volume level of the audio equipment source.

4.CHANNEL B SIGNAL LED Same operation as Channel A LED

5.LEVEL CHANNELS (1 - 4)

Each control adjusts the Output volume of outputs 1-4 from

–∞to +6dB.

6. LEVEL CHANNELS (5 - 8)

Each control adjusts the Output volume of outputs 5-8 from

–∞to +6dB.

1. FUSE HOLDER & POWER CORD CONNECTOR

This fuse holder contains an AC primary fuse. When this fuse blows, replace it with the same type fuse, size and power rating (see SPECIFICATIONS). If it continuously blows, stop replacing the fuse and refer servicing to qualified personnel. The cord connector is used to connect the AC power source to your power amplifier.

(CAUTION: After checking the AC supply voltage, be sure that the correct fuse is in the fuse holder.)

CAUTION: DO NOT REMOVE THE AC PLUG CENTER GROUNDING PIN.

2. SELECT SWITCH

This push button switch selects the mode of operation. When the switch is out, Single Mode 1-8 (mono) is selected. Depressing this button selects Dual Mode 2-4 (stereo).

5.OUTPUT CONNECTORS (1 - 4) Balanced XLR outputs for Ch. A signal.

6.OUTPUT CONNECTORS (5 - 8)

Balanced XLR outputs for Ch. A signal, when in Single Mode, and Ch. B signal when in Dual Mode.

Note: All output signals are in-phase with the input signal.

7.INPUT VOLTAGE SELECT SWITCH (BOTTOM PANEL) Select 115V/60Hz or 230V/50Hz as appropriate for your area.
