Owners Manual
Firstly, let us congratulate you on your purchase of the Ascent Two EQ Microphone Pre-
Amplifier/DI/Eq. The Ascent Two EQ is a 4 Band Gyratory-based Eq with 12 selectable
frequencies, and Mic, Line, and DI inputs We know you will be as pleased with it’s sonic
qualities as we are.
You are now the proud owner of a Mic-pre/DI/Eq that has the advantages of more than 25
years experience in audio engineering, today’s component and manufacturing technology, but
still retaining “that sound” uniquely achievable through Class A design.
As you can tell, Phoenix Audio is dedicated to the development of Class A discrete
technology used within high build-quality equipment.
The Ascent Two EQ uses our well proven and loved Class A output stage (DSOP-2), but
also has our latest breakthrough in transformer-less Class A, Discrete, truly-balanced
Mic Input Technology which gives a "valve-like" sound. It also incorporates our high
input impedance DI circuitry.
You CAN hear the difference!!!

CONNECTIONS AND CONTROLS
Front Panel
Rotary Gain Sensitivity Switch: The sensitivity switch operates in both Mic and Line Mode. For Microphone
mode the switch’s gain range is marked from -30dB to -70dB. When the switch is pressed in the sensitivity Pad
of the gain control is -15dB lower than the marked gain.
Output Level Rotary knob: The Output level knob controls the level at the output XLR on the rear panel only.
It does not affect the input sensitivity.
Level LED’s: The LED’s are marked 0 (Green) and +8 (Red). These are set to illuminate at 0dB and +8dB
(Corresponding to 4 and 6 on a PPM Meter). The LED’s are PPM style metering and have some hysteresis to
allow a better view of fast changing levels.
These LED’s are connected to the OUTPUT stage of the unit to give you a clear view of what level is being sent
to external equipment.
DI Input ” Jack socket: ¼The Jack socket is a TS socket wired Tip-Hot, Sleeve-Cold. The DI input is a high
input impedance circuit (without the use of FETs), and is capable of accepting a wide range of instruments, from
keyboards to guitars and more.
EQL Push Button: Engages the Gyratory Based Eq circuit when depressed.
DI Push Button: Disconnects the Input XLR and engages the DI Jack on the front panel.
HPF Push Button: Engages the High Pass Filter. The filter is active regardless of which input is being used.
Phase Push Button: Reverses the Phase of the Input XLR only.
+48V Push Button: Applies 48V Phantom Power to the Input XLR. The phantom power will be applied to the
XLR in both Mic and Line mode.
Mic/Line Pad Push Button: Switches the Input XLR between Mic/Line and a 15db lower level (depressed)
mode and is always lit orange.
Earth Lift Push Button: Disconnects internal 0v from the chassis earth. This is for use when using
microphones with their own PSU, or can be useful in situations where hum is being created by an earth loop.
This push-button does not disconnect the chassis safety earth from the mains earth.
REAR PANEL
Mic Input XLR: This XLR accepts both Microphone and Line level inputs. These can be balanced or
unbalanced inputs.
Output XLR: Transformer balanced output. Can be used at the same time as the Output ” TRS Jack¼, as long
as total loading does not exceed 200R.
INPUT and OUTPUT connections:
The Ascent Two EQ is fitted with an XLR input on the rear panel. The XLR's are industry-standard Pin 1 -
Ground, Pin 2 - - Cold. Hot, Pin 3
The DI input is a standard 1/4" (6.35mm) mono jack socket (wired Standard - -hot, Sleeve-Ground) Tip
The Output of the unit is on the rear of the unit and is available on both a 3 Pin XLR (wired as the input XLR),
and a Stereo 1/4" (6.35mm) Jack socket (wired Tip-Hot, Ring-Cold, Sleeve-Ground). The outputs are wired in
parallel.
