Description
Nemesis Technology, Inc. is proud to introduce the Reverb2 Version of our popular NemFX
Series of Digital Reverb and Multi-Effects Modules. NemFX Reverb2 features an extremely
high quality Reverb program available in two delicious flavors –- Spring or Room. You
can select one of three Reverb Decay Time options -- Short, Medium, or Long. NemFX
Reverb2 is available in either a Vertical-Mount or Horizontal-Mount form factor.
Theory of Operation
The NemFX Reverb2 Module is a tiny daughter card assembly which can be installed on main
boards in products such as guitar amplifiers and portable PA systems. Connection to the
NemFX is simple. It has one analog input pin and two analog output pins for easy mono in
and stereo out operation.

Application Information
Input Circuit
The NemFX Module requires a low impedance drive directly from the output of an op-amp.
Any resistance on the input connection to the NemFX Module will cause distortion on the
input signal. The input analog signal can be up to a maximum of 3.22 Vpp before clipping
occurs. Analog input signals must stay within the voltage range listed under ‘Absolute
Maximum Ratings’ in the specifications section of the datasheet; otherwise, damage to the
NemFX Module can occur.
Output Circuit
Interfacing to the analog output of the NemFX Module is also very simple. The output
circuit on the module must drive a load greater than 2 kΩ. For applications that use
only a single channel, the two Outputs can be summed to improve the dynamic range
performance. Or is saving cost is critical, connect only to one Output (either is fine).
Additional filtering of signals above 50 kHz may be necessary on systems that are
sensitive to high frequency noise.

Changing Reverb Type and Reverb Decay Time
When your NemFX Reverb2 Module ships from our factory, it is configured to the Reverb
Type and Reverb Decay Time that you specified when placing your order. The Module does
however provide a means for changing the Reverb Type and Reverb Decay Time. On the right
side of the Module are three locations for soldering 0 ohm 0603 surface mount chip
resistors. The first location is labeled SPRING. To select Spring, install a 0 ohm
resistor. To select Room, leave this location un-populated.
The next two locations are labeled S and L. To select Short Decay Time, install a 0 ohm
resistor in the S location only. To select Long Decay Time, install a 0 ohm resistor in
the L location only. To select Medium Decay Time, leave both the S and the L location
un-populated.
Ordering Options
NemFXReverb2-Type-Decay-Mount
Type

Spring
Decay
S – Short
M – Medium
L - Long
Mount
H – Horizontal
V - Vertical
For example, to order a Vertical Mounted Medium Spring, the Part Number would be
NemFXReverb2-Spring-M-V. Or to order a Horizontal Mounted Long Room, the Part Number
would be NemFXReverb2-Room-L-H.
