About the IOTAVX Integrated Amplifier SA 3
The IOTAVX SA 3 Integrated Amplifier with Bluetooth is designed and built in-house with the same quality and
attention to detail we have been bringing to all our entire audio range.
With 50 Watts per channel, the ability to match with the IOTAVX PA 3 for additional power, as well as an array
of digital and analogue inputs including Phono (MM) and Bluetooth, the SA 3 is a truly versatile machine while
remaining elegantly simple to use.
Although the SA 3 is a well featured and is extremely flexible, its most defining characteristic really is the sound!
The premium quality Toroidal power transformer and discrete amplifier stage seamlessly deliver a beautifully rich
sound with very low noise (only 0.07% THD).
Product Description
Front Panel
1. Standby Indicator Light
When the power amplifier is in standby, the light will glow red. When the power amplifier is in operating mode it
will glow white. When the power amplifier has detected a problem (protection due to short on output for
example) the light will blink red.
2. Volume Control
Controls the volume level of all audio channels, as well as access to the various menu functions and adjustment.
3. Headphone Jack
Output audio signals for the use of listening with headphones.
4. VFD Display
A vacuum fluorescent display (VFD) is used to display all menu details and functions.
Rear Panel

You have the option of using multiple analogue inputs namely PHONO (MM), LINE1, LINE2, LINE3, LINE4, LINE5.
2. REC OUT
This analog audio output is for connecting a recorder with an analog audio input.
3. PRE-OUT
If you want to connect to the IOTAVX PA3 power amplifier and use SA3 as a preamplifier, connect it to the PRE-
OUT jacks.
4. SUB-OUT
This is to connect an Active Sub-woofer.

and White. Use Red plugs to connect right-channel audio
inputs and outputs (typically labeled “R”). Use White plugs to
connect left-channel audio inputs and out-puts (typically labeled “L”).
•Push plugs in all the way to make good connections (loose
connections can cause noise or malfunctions).
•To prevent interference, keep audio and video cables away from
power cords and speaker cables.

Cables and Jacks
Analog
audio
cable
(RCA)
This cable carries a Stereo Analogue Audio
Signal. It’s the most common connection
format for Analogue Audio and can be found
on virtually all A/V components.
•The Red Plug carries the Right-Hand Side
Audio Channel.
•The White Plug carries the Left-Hand Side
Audio Channel.
Mono mini-
plug
Use the supplied or commercially available
mono mini-plug cable to connect to the
TRIGGER IN / OUT or DIMMER IN OR OUT jacks
on the other device for linked operation.

Speaker Connections
•Disconnect the power cord from the wall outlet before making or changing any connections.
•Check the impedance of your speakers. Only connect speakers with an impedance of 4 ohms or more.
•The amplifier’s red speaker terminals are the + (positive) terminals and the black terminals are
the –(negative) terminals. The + side of the speaker cable is marked to make it
distinguishable from the –side of the cable. Connect this marked side to the red +
terminals and the unmarked side is the black terminal.
•Prepare the speaker cables for connection by stripping
off approximately 10 mm or less of the outer insulation
(no more as this could cause a short circuit). Twist the
wires tightly so that they do not have any frayed or loose
ends.
Making the Speaker Cable Connections:
1. Unscrew the Knob
2. Insert the bare speaker cable end through the hole in the post
3. Tighten down the knob (finger tight only)
to secure the cable

Stereo Connection
This is an example of the stereo connection using the CD player or other device.
Please Note!!
Set the Amplifier Mode switch to Stereo Mode
Mono (Bridge) Connection
This is an example of the Mono (Bridge) connection with the CD player, SA3, PA3. Please note that when used
as a mono power amp, the SA3 will always amplify the right input signal and output to the connected speaker.
Please connect the PA3 to the left preamp output "PRE-OUT" of the SA3.
Please Note!!
Set the amplifier Mode switch to Mono (Bridge) position.

Analogue Audio Output Jacks:
This unit has one pair of Analogue Audio Output Jacks. This output can be used to send a signal of what is
currently being listened to, to an analogue recording device such as a Tape Recorder.
•Connect to Recording equipment using Analogue RCA cables (Stereo 2RCA-2RCA):
Subwoofer Pre-Out:
This unit has a single Mono Subwoofer Pre-Out Jack, SUB OUT for connection to an Active (Powered) Subwoofer.
This jack will output a low frequency signal and its level is automatically raised and lowered along with the main
Volume control.
•Connect to an Active (Powered) Subwoofer using Analogue RCA cable (Mono 1RCA-1RCA):
NOTE: The SUB OUT Jack is constantly active, and the level is controlled automatically by the main Volume
control.

Troubleshooting
To determine any problem with your integrated power amplifier, always check the most obvious possible causes
first. If any problems remain after you have checked the items below, please consult your nearest Authorized
Dealer or Authorized IOTAVX Service Center.
If you experience any of the following difficulties while using the system, use this troubleshooting guide to help
remedy the problem before requesting servicing. Should any problems persist, consult your nearest authorized
dealer or authorized Service Agent.
If the unit does not operate normally due to external influence such as static electricity, disconnect the power
plug from the wall outlet and insert again to return to normal operating conditions.
PROBLEM
POSSIBLE CAUSE
REMEDY
Main Amplifier:
When listening to the music in stereo.
Left/right speakers reversed.
Speakers are connected incorrectly.
Check, and reconnect as required.
Sound is only heard from one
channel.
One of the input cords is
disconnected.
Connect the input leads.
Sound cuts off when listening or no
sound even though power is ON.
Speaker impedance is lower than
recommended for this unit,
therefore overloading the Amplifier.
After turning off the power and
then turning it on again, reduce
the volume or change to the
correct 4/8-ohm speakers.
Low bass response.
Speaker polarity (+/-) is reversed.
Check all speakers and speaker
wires for correct polarity.
