2. Do not use this product near water (e.g., near a bathtub, washbowl, kitchen sink, in a wet basement, or near a swimming
pool, etc.).
3. This product should be used only with a cart or stand that will keep it level and stable and prevent wobbling.
4. This product, in combination with headphones or speakers, may be capable of producing sound levels that could cause
permanent hearing loss. Do not operate for a long period of time at a high volume level or at a level that is uncomfortable.
If you experience any hearing loss or ringing in the ears, you should consult an audiologist.
5. The product should be positioned so that proper ventilation is maintained.
6. The product should be located away from heat sources such as radiators, heat vents, or other devices
(including amplifiers) that produce heat.
7. The product should be connected to a power supply only of the type described in the operating instructions or as marked on the
product. Replace the fuse only with one of the specified type, size, and correct rating.
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.
10. The product should be serviced by qualified service personnel if:
A.
B.
C.
D.
E.
The power supply cord or the plug has been damaged.
Objects have fallen into, or liquid has been spilled onto the product.
The product has been exposed to rain.
The product does not appear to operate normally or exhibits a marked change in performance.
The product has been dropped, or the enclosure damaged.

INSTALLATION
To ensure years of enjoyment from your NADY AUDIO RPA-2, please read and understand this manual thoroughly before
using the unit.
INSPECTION
Your RPA-2 was carefully packed at the factory in packaging designed to protect the units in shipment. Before installing and using your
unit, carefully examine the packaging and all contents for any signs of physical damage that may have occurred in transit.
(Note: Nady Systems is not responsible for shipping damage. If the unit is damaged, do not return to us, but notify your dealer and the
shipping company immediately to make a claim. Such claims must be made by the consignee in a timely manner.)
CONTENTS:
• Instruction manual
• RPA-2 (verify that the unit’s serial number is same as shown on shipping carton)
• AC Power cord
• Warranty Card
POWER CONNECTION
The RPA-2 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 back 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 which can damage your speakers or your ears, especially when monitoring with
headphones.

FRONT PANEL
Note: 1 through 5 below are referenced to Channel 1. The other
channels are identical.
(Note: Only either the Mic or the Line input of a given channel can
be connected at one time. Do not connect both simultaneously to
the same channel.)
(1) GAIN CONTROL
The Gain Control determines the proportion of the channel signal
in the mix.
(6) MASTER — VOLUME CONTROL
This controls the final level of the signal output.
(7) MASTER — REVERB CONTROL
This controls the level of the reverb effects sound.
(2) CONTOUR CONTROL
Adjusting this control will contour the audio, either bringing out
more highs and definition or increasing low and mid frequencies to
provide more punch.
(8) MASTER — HIGH CONTROL
The control has a shelving response giving 15dB of boost or cut at
12KHz.
(3) REVERB CONTROL
The Reverb Control adjusts the level of signal sent by each
channel to the internal Reverb DSP (Digital Sound Processor).
The signal sent is mono, post-Contour and will be affected by the
channel Gain Control.
(9) MASTER — MID CONTROL
The control has a shelving response giving 15dB of boost or cut at
1.5KHz.
(10) MASTER — LOW CONTROL
(4) LINE INPUT
The control has a shelving response giving 15dB of boost or cut at
100Hz.
The Line input is designed to accept balanced or unbalanced line-
level signals such as those from keyboards, drum machines, or
samplers. Use the GAIN control (1) to adjust for the desired level.
If a balanced signal is to be connected to the line input, then a
1/4" TRS (stereo) phone plug should be wired for: Tip = positive
(+), Ring = negative (-), Sleeve = ground.
(11) MASTER — DEPTH CONTROL
This controls the amount of feedback of the reverb reflection, i.e.
the number of reflections and the length of time before they
diminish in volume.
(5) MIC INPUT
(12) POWER ON LED INDICATOR
Indicates when the unit is ON.
The Mic input is an electronically balanced XLR type designed to
accept signals from any balanced low impedance (Low Z)
microphone. It will be necessary to adjust the channel gain with
the input GAIN control (1) to achieve a nominal operating level.
The XLR jack is configured for: Pin1 = ground, Pin2 = positive (+),
Pin3 = negative (-).

(15) AUXILLIARY OUTPUT
This line level output can be connected to external recorders,
amplifiers, or effects processors. The signal is a mix of the
channel inputs determined by each Channel Gain control.
This line level output can be connected to external recorders,
mixers, or amplifiers.
(16) TAPE IN AND TAPE OUT
(14) EFFECTS RETURN
The Left and Right TAPE IN allows cassette recorders or CD
players to be added to the Main output. The RECORD OUTPUT,
with TAPE RCA jacks, provides signal output to a cassette deck or
home audio equipment.
This input can be used to return the effected signal into the RPA-2
or it can be used as an auxiliary input. The input signal can be
adjusted by the Master Volume and the unit the Return jack is
connected to.
REAR PANEL CONTROL & CONNECTIONS
(19) POWER CONNECTOR WITH FUSE HOLDER
This standard IEC power cord receptacle is used to connect the
AC power to your unit. It features a built-in fuse holder for a
5X20mm, (2.5A/250V for 115VAC, and 1.5A/250V for 230VAC
operation) fast-blow fuse. If the fuse continuously blows, shut off
the unit and have it serviced by qualified service personnel.

(20) EXTERNAL SPEAKER OUTPUT
(20)
(21)
1/4" (6.3mm) jack for connecting an external speaker cabinet to
the RPA-2. The connected speaker impedance must be 8 ohms
or greater. The RPA-2 external speaker output delivers 25W RMS
of power @ 8 Ohms.
CAUTION: Do not overload the RPA-2 with speaker loads less
than 8 ohms as this will degrade performance and may harm the
unit. Damage caused by improper use is not covered by the
warranty.

REAR PANEL
(17) POWER SWITCH
Turns the unit ON or OFF. Always turn level controls down before
turning on the unit.
(21) LINE OUTPUT
This 1/4" (6.3mm) audio output is line level, post Master Volume,
designed for connecting to external recorders, mixers, or amplifi-
ers.
(18) VOLTAGE SELECTOR SWITCH
For selecting the proper voltage (115/230VAC) to match the power
supply in your area.
Note: To avoid damage to your unit, always make sure this switch
is set to the correct supply voltage. Damage caused by improper
use is not covered by the warranty.
