20. MAIN OUTPUT LEVEL: This back panel control is an attenuator on the main XLR and 1/4" outputs. It is provided
to match the nominal operating levels of the S-4 ™ to the inputs of either a mixing console, power amplifier
or recording device. It has a 30 dB attenuation range, allowing it to adjust from line to microphone levels as
required.
21. MAIN OUTPUTS (XLR and 1/4"): These independent, 1/4" unbalanced and XLR balanced outputs have their level
set by the master level control and the rear panel trim control. The nominal levels are +4dBu with the
output trim set to 0.
NOTE: Pin 1 of the XLR output connector is connected to chassis ground using a resistor-capacitor network to
minimize the chance of ground loops when connected to the main sound system.
22. LINK IN and LINK OUT: These TRS 1/4" jacks are used to interconnect S-4 mixers when additional inputs are
required. A single TRS-TRS shielded cable connected between the link out of the first S-4 and the link in of
the next S-4 ties together audio and control signals. Up to 10 units can be slaved together using this system.
When the S-4s are linked, the same audio signal appears at each S-4 output. The front panel master level
and rear panel output level controls only affect the signal level from that S-4’s output.
NOTE: The S-4's are NOT connected in a ring. The link in jack of the first and the link out jack of the last
S-4 mixers must be empty.
23. MIC +48V: A rear panel switch applies 48 Volt phantom power to the input XLR connectors for powering
microphones that require it. If phantom power is used, do not connect unbalanced dynamic microphones
or other devices to the XLR inputs that cannot handle this voltage. An LED on the front panel indicates that
phantom power is on. Phantom power is not applied to the 1/4" line inputs.
24. AC MAINS INPUT: Connect the line cord to this connector to provide power to the unit. Damage to the
equipment may result if improper line voltage is used. Operate only with the specified AC input voltage
applied.
U.S DOMESTIC AC MAINS CORD
The mains cord supplied with the unit is a heavyduty, three-conductor type with a conventional 120 VAC plug with
ground pin. If the outlet used does not have a ground pin, a suitable grounding adapter should be used and the third
wire should be grounded properly.
Never break off the ground pin on any equipment. It is provided for your safety.
