Phono Preamplifier: The Music Hall pa2.2 is phono preamplifier which
can be used with turntables what are quipped with moving magnet (MM) or high
output moving coil (MC) cartridges.
- MM/MC Input: The Music Hall pa2.2 is equipped with a MM and MC phono
input. Before setting the MM/MC switch, the unit must be disconnected from
the power supply and amplifier. Once disconnected choose the appropriate
setting MM/MC for the cartridge you're using.
- MC Gain: If you are using an ultra-low output moving-coil
cartridge you can add an additional 6dB of gain by switching the mc gain switch on the back to 26dB. If
you're using a standard low-output moving coil cartridge best results will
be obtained with the 20dB gain setting.
- Ground Terminal: The pa2.2 phono preamplifier/headphone
amp has a turntable ground, in case your turntable has a separate ground
lead. This provides shielding to the tone-arm and the sensitive circuitry in
Headphone Amp: The Music Hall pa2.2 is also a headphone amplifier with
a front-panel 1/4" headphone jack to connect one pair of headphones (32-600
ohms). The rotary knob on the front-panel can be used to control the volume
level of the headphone out.
Line Input: A rear-panel analog stereo RCA input allows you to connect
a CD player, tape deck or tuner to the Music Hall pa2.2 phono
preamplifier/headphone amp. The Line Input is output from the pa2.2's fixed or
variable line outputs, headphone output, and USB-B out.
Fixed or Variable Line Out: One the rear-panel of the pa2.2 you have
the choice between a variable or fixed analog stereo RCA output to connect to
your power or integrated amplifier. The variable output will allow you to
adjust the volume level of the output with the volume control on the front-panel
of the Music Hall pa2.2. The fixed output requires you adjust the volume level
from your amplifier.
A/D Converter w/ USB-B Out: The Music Hall pa2.2 is equipped with a
Wolfson WM8786, Tenor TE7022L 24-Bit Delta-Sigma A/D converter and USB-B out for
connecting the phono preamp to your Windows PC (XP-up) or Mac computer (OSX
10.6.6-10.11). By connecting the pa2.2 to your Windows PC or Mac computer, you
can record your vinyl records as 2ch PCM digital music files (up to 24-bit/96kHz). When you
plug in the pa2.2 your computer will automatically recognize it and download any
necessary drivers. You will need to download a 3rd party recording software. The
preamp's Line Input can also be recorded via USB to your computer.
Note: For recording to your computer with the pa2.2, Music Hall recommends the use
of the free Audacity recording software. The Audacity recorder and audio editor for your computer
can be downloaded and set-up at
Front-Panel Controls: The pa2.2 phono preamplifier/headphone amplifier
is equipped with four two-way switches and rotary knob on the front-panel.
- On/Off Switch: Use this switch to power the unit on and off.
- Stereo/Mono Switch: Switch between stereo or mono audio output.
The sound of mono records is significantly improved by toggling this switch
- Phase/Invert Switch: Switches the output signal between absolute
polarity phase (0 degrees) and reversed polarity
invert (180 degrees). The majority of recording are in phase, but some are recorded
inverted phase or out-of-phase. The music will sound more full and rich when
matched to the correct phase.
- Phono/Line Switch: Switches the audio output between phono and
- Volume Knob: Turn this knob to adjust the headphone and variable
output volume level.
Rigid Extruded Aluminum Housing: The pa2.2 phono preamp/headphone amp
features a rigid extruded aluminum chassis to ward off the effects of stray
magnetic fields and provide a safe quiet environment for the sensitive
electronics it houses, thus providing you with the best sound possible from your
External Power Supply: The pa2.2 phono preamp/headphone
amplifier operates off of standard household AC current, using the supplied AC
power adapter. The external power adapter is separate from the phono preamp to
further improve sound quality.
- Input: 100-240V ~
- Output: 24V - 630mA
