8. The power supply cord should: (1) be undamaged, (2) never share an outlet or extension cord with other

devices so that the outlet’s or extension cord’s power rating is exceeded, and (3) never be left plugged into

the outlet when not being used for a long period of time.

9. Care should be taken so that objects do not fall into, and liquids are not spilled through, the enclosure’s

openings.

RACK MOUNTING

The SD-2418 fits into one standard 19”rack unit of space (1 3/4”). Parts of the unit can become very warm during use.

This is normal during operation. Care should be taken to ensure that there is enough space around the unit for cooling (at

least 12”or 30cm). Do not place the SD-2418 on high temperature devices such as power amplifiers, etc., or the unit may

overheat in operation. Also, do not place the unit on speakers as this may cause them to move and/or fall due to speaker

vibrations.

Although the unit’s chassis is shielded against radio frequency (RF) and electromagnetic interference (EMI), extremely

high fields of RF and EMI should be avoided.

POWER CONNECTION

The SDR-260 has an internal power supply and is designed to operate from an external AC source. Power requirements

for electrical equipment differ from area to area. Be sure to confirm that the voltage selected by the voltage selector switch

on the bottom panel is proper for your area (120VAC/60 Hz or 230VAC/50Hz) per the information below:

Europe (except UK): 230V, 50Hz

UK and Australia: 240V, 50Hz

USA and Canada: 120V, 60 Hz

For other areas, please check with local authorities.When ready to operate, plug the AC cord into the power source. Make

sure that the unit is turned off before connecting to the AC power source to avoid possible loud transients that can

damage your speakers or your ears, especially when monitoring with headphones.

CONTROLS AND CONNECTIONS

(1) (2) (5)

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).

3. INPUTS

Channel A and Channel B XLR balanced line level inputs.

4. LINK OUTPUTS

Ch. A and Ch. B XLR outputs linked in parallel with the

respective input.

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.

(CAUTION: Selecting the wrong voltage can damage your unit.
