INSTALLATION
To ensure years of enjoyment from your NADY AUDIO TMP-3 please read and understand this manual thoroughly before
using the unit.
INSPECTION
Your TMP-3 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:
• TMP-3 (verify that the unit’s serial number is same as shown on shipping carton)
• AC Power cord
• Instruction manual
• Warranty Card
RACK MOUNTING
The TMP-3 fits into one standard 19" rack unit of space (1 3/4"). Parts of the unit can become very warm during use. This is normal
during operation. Care should be taken to ensure that there is enough space around the unit for cooling (at least 12” or 30cm). Do not
place the TMP-3 on high temperature devices such as power amplifiers, etc., or the unit may overheat in operation. Also, do not place
the unit on speakers as this may cause them to move and/or fall due to speaker vibrations.
Although the unit’s chassis is shielded against radio frequency (RF) and electromagnetic interference (EMI), extremely high fields of RF
and EMI should be avoided.
POWER CONNECTION
The TMP-3 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 (120 VAC/60 Hz or 230 VAC/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.

(7) LOW LEVEL EQ CONTROL
Adjusts level of low frequencies, from 20Hz to 150Hz.
(1) POWER SWITCH
Use this switch to power unit ON or OFF. The integrated LED will
light when the unit is ON. Before turning on this unit, verify
connection to the proper voltage AC source, check all connections
and turn down the level controls of equipment connected to the
outputs. (Note: The TMP-3 will not output audio for approximately
16 seconds after power up due to the time it takes for the tubes to
warm up. Do not turn up the audio until after this warm up period
to avoid possibly damaging speakers or your hearing due to
improper level settings.)
(8) MID LEVEL EQ CONTROL
Adjusts level of mid frequencies, as selected by the MID SWEEP
(9) control. This sweepable filter has a Q or width of 1.
(9) MID SWEEP CONTROL
Selects the frequency to be boost/cut by the MID LEVEL (8)
control. Adjustable from 300Hz to 5KHz.
(10) HIGH LEVEL EQ CONTROL
Adjusts the level of high frequencies, from 10kHz to 20kHz.
(2) +30dB GAIN/NORM SWITCH
Use the +30dB GAIN/NORM switch to set the gain range of the
INPUT CONTROL (2). When the switch is out, the TMP-3
operates in Normal mode, depressing the switch adds +30dB of
gain. Push the switch in for microphone applications when more
level is needed.
(11) IN/OUT SWITCH
Switch for engaging the compressor circuits. The compressor is
active when the switch is in.
(12) THRESHOLD CONTROL
Sets the point that the input signal must reach for compression to
begin.
(3) PHASE REVERSE / NORM SWITCH
When the switch is in the Out position the output signal is normal.
Depressing the switch reverses the phase of the output signal. In
multi-microphone applications, mic placement can affect the
phase of the signals. If your sound is “thin” or “not quite right”,
reverse the phase to correct the problem.
(13) RATIO CONTROL
This control sets the signal to compression ratio. This ratio relates
to the amount of increase of input compared to output signal.
Thus, for example, at a 1:1 ratio, a 1dB increase of input signal
will result in a 1dB increase of out signal. At 2:1, a 2dB increase of
input signal will result in only 1dB increase of output signal. At 8:1,
an 8dB increase of input signal will result in a 1dB increase of
output signal.
(4) PHANTOM POWER SWITCH
Use the PHANTOM POWER to supply power to all microphones
requiring +48V phantom power. The TMP-3 phantom power is
engaged and disengaged with this switch Phantom power is
applied to pins 2 and 3 of the XLR INPUT (20) jacks when this
switch is pushed in. To disengage phantom power, set the switch
in the out position. PHANTOM POWER LED (4a) lights when
PHANTOM POWER is engaged.
(14) OUTPUT LEVEL VU METER
The output level of the TMP-3 can be monitored using the analog
OUTPUT LEVEL VU METER. The meter’s 0dB marking represents +12dB at the XLR output and +6dBu at the 1/4" output. The
output meter will also reflect any attenuation due to the output
limiter when it is engaged.
(5) GAIN CONTROL
Controls the amount of gain in the tube mic preamp circuit. This
control adds from 0dB to +10dB of gain.
(15) OUTPUT CONTROL
The OUTPUT CONTROL sets the output level of the TMP-3.
When the control is fully counterclockwise, the output level of the
TMP-3 is zero. Turning the control clockwise increases the level of
the output to a maximum of +10dB of gain. This gain is in addition
to the existing input gain.
(6) CLIP LED
When lit, this LED indicates clipping or possible distortion in the
mic preamp circuits. Reduce the GAIN CONTROL (5) so that this
LED only lights occasionally.

not connect to both at the same time, or the signal will be
severely distorted.)
(16) AC POWER CORD IEC CONNECTOR WITH INTEGRATED
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 5 X
20mm, 0.5A/250V slow-blow fuse. If the fuse continuously blows,
shut off the unit and have it serviced by qualified service
personnel.
(19) SIDE CHAIN
1/4” Tip-Ring-Sleeve Send/Return jack. Connect an insert cable
to this jack and to a signal processor or other device to alter the
action of the TMP-3 compressor.
(17) AC VOLTAGE SELECT SWITCH
Before plugging in the power cord, check to see that the unit is
set for the proper voltage for your area: ~115V(60Hz) or ~230V
(50Hz).
(Note: Use at the improper voltage can damage your unit and void
the warranty.)
(20) INPUTS
Unbalanced 1/4" (6.3mm) and balanced XLR inputs.
(Note: Only one input per each channel (1/4" or XLR) can be
used at one time. Do not connect to both at the same time or the
signal will be severely distorted.)
CONNECTION
Make sure the TMP-3 power cord is properly connected to a
grounded AC outlet. Note examples illustrating proper connection
of microphones and instruments to the TMP-3. Do not use both
inputs at the same time. After the TMP-3 has been properly
connected, turn the POWER SWITCH (1) on.

connect to a Mic Input.
Connect to mixer line-level input.
MIC PREAMP SETTINGS (2,3,4,5,6)
For condenser mics, press in the PHANTOM POWER (4). Press
the +30dB GAIN/NORM (2) switch in if you’re sending a line level
(+4dB) signal into the TMP-3. This helps prevent overload.
Provide a signal to the TMP-3 by connecting either a microphone
or an instrument to the INPUT (20). Adjust the GAIN CONTROL
(5) while sending the signal. When the CLIP LED (6) lights more
than just occasionally, reduce the GAIN CONTROL (5) (counterclockwise) one or two marks to achieve the proper level of
incoming signal.

Connect to mixer line-level input.
COMPRESSOR SETTING (11, 12, 13)
Press in the IN/OUT (11) switch to engage the compressor. Begin
by setting the THRESHOLD (13) control high (around 3 o’clock)

compression, lower the THRESHOLD (12) control and increase
to the signal processor Output. The signal in the SIDE CHAIN is

the RATIO (13) control until the desired amount is achieved.
the compressor. The higher the level of signal in the SIDE CHAIN,
the more compression will occur.
