Remote Turn-on
The Reference 160S has a built-in 12V DC remote turn-on/off circuit for operation by a master
control system in a home theater or large audio system. Use a 3.5mm (.140”) diameter mini
plug to connect to the +12V IN jack on the rear of the Reference 160S. The tip of the mini plug is
+12V and the sleeve is ground.
The +12V IN jack should be connected to the +12V DC output of the master control system,
using a cont12V DC signal at 12mA for the duration of amplifier on-time. Do not use a
momentary or data pulse control signal.
The +12V DC remote jacks have polarity protection, so they will not operate if a-12V DC signal is
accidentally connected, or if the control wires are reversed.
RS-232 Control
The Reference 160S has an RS-232 connector on the back panel, in the event the amplifier is
incorporated into an automated or two-way remote communication system. Please see your
dealer or contact [email protected] to acquire specific codes relative to the RS-232
control.
A.C. Power Connection
It is important that the Reference 160S be connected via its supplied 20 amp IEC 12-gauge power
cord to a secure, dedicated A.C. power receptacle. Never connect to convenience power
receptacles on other equipment. Only use the power switch on the front of the Reference 160S
for On/Off control of the amplifier, or the 12V start-up trigger or RS-232 for remote
installations.
The AC power source for the Reference 160S amplifier should be capable of supplying 15
amperes for 100 or 120 volt units, or 10 amperes for 220 or 240 volt units.
For the very best performance on 100 or 120 volt circuits, the Reference 160S should be
connected to its own AC power circuit branch, protected by a 15 (or 20) amp breaker. The
preamplifier and other audio equipment should be connected to a different power circuit and
breaker, if possible.
The Reference 160S uses a grounding system that does not require a ground- lifter adapter plug
on the A.C. power cord to minimize hum. The power cord supplied with the Reference 160S has
a standard grounding plug to provide maximum safety when properly connected to a grounded
wall receptacle. If there is any question regarding proper grounding procedures in your
installation, seek help from a qualified technician. Caution should be taken before using
custom after-market power cords: they must be at least 12-gauge and have a standard
grounding plug properly installed. These power cords are to be used with caution, at the sole
risk of the owner. If electronic crossovers or other AC powered equipment is used with the
Reference 160S it may be necessary to use ‘ground lifter’ adapters on the power plugs of that
