1.0) INTRODUCTION
The Phonomena II+ is a complete phonograph preamplifier with RIAA
equalization that amplifies the output signal of a phonograph cartridge up to
a nominal “line level”. It is a discrete, dual-mono design, designed and made
in the USA. The Phonomena II+ may be used with either moving-coil or
moving-magnet cartridges. Its flexibility in gain and loading settings lets you
optimize the performance of your phono cartridge and match volume levels
with other source components in your system. The Phonomena II+ can be
connected to a receiver or an integrated amplifier. If you use separate
components, a line level control unit (preamplifier) is required before the
power amp, since there is no volume control on the Phonomena II+. The
Phonomena II+ internal power supply connects to an AC outlet with the
supplied wall-mount transformer.
Installation and set-up of the Phonomena II+ is quite simple. It involves:
a.) Setting the four external configuration settings (two for each channel)
for Gain and Input Loading (see section 2).
b.) Connecting to an AC power outlet with the supplied wall-mount
transformer (see section 3).
c.) Connecting the Audio Inputs and Outputs (see section 4)
d.) Placing the unit (see section 5).

2.0) EXTERNAL CONFIGURATION SETTINGS
2.1) BASIC GAIN SETTINGS
To Set the Gain, there are two sets of four dip switches, located on the
Phonomena II+ back panel (one set each for the left and right channels).
Refer to your phonograph cartridge’s instruction manual for the suggested
Gain setting. Factory Settings are always 40dB for Gain.
Lower Gains (40 and 44dB) are effective for moving-magnet cartridges or
very high output moving-coil cartridges (>2.0mV). Medium Gain settings (46
and 50dB) are ideal for medium-output moving-coils (.9-1.5mV). High Gain
settings work well with low-output moving-coil cartridges. To change
settings, use a non-metallic object to push the switches UP for the ON
position.

Always let the unit settle for 60 seconds after any configuration changes are
made before listening. Slowly raise the volume after making any change.
This will ensure that the unit is stable and will not damage your system if the
configuration is not set correctly. You can select gain settings to more closely
match your turntable to other source components in your system.

2.3) BASIC INPUT LOADING SETTINGS
INPUT LOADING SWITCH
To set the Input Loading, there are two eight-position switches, one for each
channel, located on the rear panel. Refer to your cartridge owner’s manual to
determine proper Input Loading settings. The factory setting for Input
Loading is 47,000 (47k) Ohms.
Switch #1 controls capacitive loading, which is used with moving-magnet
cartridges and has little effect on moving-coil cartridges. When using a
moving-coil cartridge, try both capacitive loading positions to determine the
effect. CAPACITIVE LOADING (SWITCH #1): OFF=200pF; ON=300pF.
Switches #2-8 control resistive loading, which is primarily used with lower
output moving-coil cartridges. Most moving-magnet along with medium and
high-output moving-coil cartridges use 47,000 Ohms. Low-output moving-
coil cartridges typically use 2000 Ohms or less. Resistive loading at 10x the
internal impedance of the cartridge is the recommended lowest loading.
Check the chart below and select the lowest Input Loading value in the
cartridge manufacturer’s recommended loading value range. A lower resistive
setting provides increased focus and tighter bass, while a higher setting
provides more openness. Use a non-metallic object to select the preferred
settings, pushing the switch UP to activate the ON setting.

3.0) POWER SUPPLY
The Phonomena II+ connects to a wall outlet or power strip with the supplied
wall-mount transformer. The unit will not operate without the wall-mount
transformer.
4.0) INPUTS AND OUTPUTS
Please make sure that the volume control on your receiver, integrated amp,
or pre-amp is turned completely down before plugging in the audio
connections. Connect the phonograph cables of your turntable to the inputs
of the Phonomena II+, noting proper left and right connections. Attach the
turntable’s ground lead to the ground lug on the rear panel of the unit.
Using a high-quality interconnect cable, connect the outputs from the
Phonomena II+ to the line-level input of your receiver, integrated amplifier
or pre-amp, again noting proper left and right channels. DO NOT PLUG THE
PHONOMENA II+ OUTPUT INTO A “PHONO” INPUT. Use the standard LINE IN
jacks, as phono jacks include special circuitry that is not needed when using
an external phonograph preamplifier.
5.0) UNIT PLACEMENT
The Phonomena II+ may be placed under your turntable if space allows, on a
separate shelf in your audio rack, or on top of another source or line-level
component. Please make sure that ventilation to the unit is not restricted,
and that the unit is away from magnetic fields or noise from other
components’ motors, transformers, digital circuitry, or displays.
6.0) USING YOUR PHONOMENA II+
If you have followed the above instructions, you are ready to play music.
Simply cue down your cartridge on a favorite record, select the correct input
on your receiver, integrated amp or pre-amp, slowly bring up the volume
level, sit back and enjoy the music.
