TECHNICAL SPECS - FRONT PANEL [SINGLE-CHANNEL]
5. Tone Switch
This switch changes the input transformer configuration from a 1:9 (step up) turns ratio to a steeper 1:18 (step up) turns
ratio, drawing out a greater degree of coloration and impact from the input transformer. When engaged, the input
impedance of the WA-MPX is 150 ohms. When disengaged, the input impedance of the WA-MPX is 600 ohms. This
feature will make a noticeable tone change to most microphones. The 600 ohms impedance setting is recommended
for condenser and dynamic microphones, and 150 ohms is recommended for dynamic and ribbons. This switch is
labeled "Tone" for a reason; most listeners will find the unswitched setting to be more open and natural, with the en-
gaged setting to be more punchy, aggressive, or thick. We strongly suggest you experiment with both settings on all
sources to find the best possible tone for your recordings. As with all things, let your ear be the final judge on which
setting to use for any given situation.
6. TS Instrument Input
You can connect a variety of instruments via the instrument input on the front panel of the WA-MPX including: acoustic
and electric guitars, bass guitar, keyboards, synths and drum machines.
7. 80Hz Hi-Pass Filter
This switch removes frequencies below 80Hz to help control unwanted bass noise from unruly sources.
8. 2kHz Low-Pass Filter
This switch removes frequencies above 2kHz for more punch and focused midrange.
9. Tape Saturation Control
This switch adds a dedicated circuit of discrete analog components to the already warm tubes, delivering tape-style
saturation - with added natural compression and harmonic distortion.
10. Preamplifier Gain
This knob adjusts the amount of tube gain applied in the WA-MPX channel circuit.
11. VU Meter
The VU meter allows for accurate monitoring of the signal volume exiting the WA-MPX channel.
12. Output Level
This knob acts as a 600Ω output attenuator, controlling the signal exiting the WA-MPX channel. The output level
ensures that the amplified signal doesn't exit the WA-MPX at too-high a volume and prevents overloading the inputs
on your recording interface or the next device in the signal chain. It also gives greater ability to drive the gain of the
preamp harder resulting in greater colorization and tone shaping within the various settings.
13. Power Switch
This switch is used to power the unit on and off. LED light will indicate if the unit is powered on. To extend the life of the
electronics please turn WA-MPX units off when not in use.
