SB168-ES Owner’s Manual

Controls and Functions

u DIP Switches 1–8

Switches 1–4 of this 8-bit DIP switch are used to set the

Setup ID as described on page 14.

i [+48V MASTER] Switch

This is the master switch for the unit’s +48V phantom power

supply. If the [+48V MASTER] switch is off no phantom

power will be supplied to the unit’s input connectors even if

the individual input phantom power settings are ON. How-

ever, the +48 indicators will light on channels for which

phantom power is turned ON even if the [+48V MASTER]

switch is OFF.

o Power Indicator

Lights when AC power to the unit is ON.

!0 [POWER] Switch

Turns power to the unit ON or OFF. Internal head ampliﬁer

settings such as gain, high-pass ﬁlter, etc., are retained in

memory even when the power is OFF.

!1 OUTPUT 1–8 Connectors

These eight XLR-3-32 type connectors deliver analog output

from the unit’s corresponding output channels. Nominal out-

put level is +4 dBu.

q Earth Screw

For maximum safety, please earth the unit properly. The sup-

plied AC power cable is a 3-wire type, so if the AC outlet

used is properly earthed the SB168-ES will be earthed as

well. If the AC outlet used is not earthed, however, please

use the earth screw to earth the unit. In addition to maximiz-

ing safety, proper earth connection also effectively mini-

mizes hum and interference.

w [AC IN] Socket

Connect the supplied AC power cable here. First connect the

AC power cable to the socket on the SB168-ES rear panel,

then plug it into an appropriate AC power outlet.

• Use only the supplied AC power cable. The use of an

inappropriate cable can result in equipment failure,

overheating, or even ﬁre.

e NETWORK Connector

An Ethernet cable can be connected from a computer to this

connector to allow updating the unit’s ﬁrmware.

• Use STP (shielded twisted pair) cable to prevent elec-

tromagnetic interference (USA, Canada, and Europe).

• Since the SB168-ES supports MDI/MDI-EX, either a

straight or cross Ethernet cable can be used.

r [FAN] Switch

Sets the internal cooling fan to operate at either HIGH or

LOW speed. This switch is set to LOW when the unit is ini-

tially shipped from the factory. As long as the unit is oper-

ated within the speciﬁed ambient temperature range either

the LOW or HIGH setting can be used. The HIGH setting is

recommended if the ambient temperature is high, if the unit

is in direct sunlight even if the ambient temperature is within

the speciﬁed operating range, and in any situation in which

fan noise is not a problem.

If two or more SB168-ES units are mounted in the same rack

and the fan speed is set to LOW, leave a 1U rack space

between every two units. Also either leave the open rack

spaces uncovered or install appropriate ventilating panels to

minimize the possibility of heat buildup. If three or more

SB168-ES units are mounted without space in the same

rack, set the fan speeds to HIGH.
