Phenyx Operating Instructions

Control Element & Connector

INPUT CHANNEL SECTION

control_elements_and_connector_phenyx_pro_sound_board_mixer_audio_ptx-15.png

BALANCE INPUT (MIC)
Standard XLR balanced input connector. +48V phantom power is available on each input mic socket.
LINE INPUT
Unbalanced mic input connector, designed for unbalanced high impedance input signal.
GAIN CONTROL
Adjust the input signal level.
HI EQ
High-range EQ control for up to 15dB of boost or cut at 12KHz and above. Use it to add sizzle to cymbals, and add an overall sense of transparency or edge to the keyboard, vocals, and guitar.
MID EQ
Mid-range EQ control for up to 12 dB of boost or cut centered at 2.5KHz. Midrange EQ is often thought of as the most dynamic because the frequencies that define any particular sound are almost always found in this range. You can create useful EQ changes by using this knob to adjust the sound.
LOW EQ
Low-range EQ control for up to 15dB boost or cut at 80Hz and below. This frequency represents the punch in bass drums and bass guitar.
EFX SEND
PAN
The pan control sends a fader signal to either the left or
right and G1 or G2 main busses. In the center position, equal amounts of signal are sent to the left and right or G1 & G2 busses.
CHANNEL FADER
Adjust the volume of the sound input from the microphone or other sources connected to each channel. It works together with the master fader. The normal operating position is at the “0” mark, providing a 4dB gain above that point if required.
PFL SWITCH
This switch enables users to monitor the channel’s pre-fader signal. Press “SOLO“ on the master panel and press “SOLO” in this section, then the channel’s pre-fader unprocessed signal will be sent to PHONES and the user can monitor the sound before output.

PHANTOM POWER SELECTION
Press this button when the phantom power supply is switched on. The phantom power supply is necessary for condenser microphones and is activated when using the Mic/Line input jack.
PHONE OUTPUT
Connect headphones to this jack to monitor output sound. If the SOLO button is pressed, you can monitor the pre-fader sound before output.

Set-Up

AC Power In
Use the included AC adapter or connect the device to a wall outlet
Audio Connection
You will need a large number of cables for different applications.
See above.
Please use commercial RCA cables to connect the 2-track inputs and outputs. You can, of course, also connect unbalanced devices to the balanced inputs/outputs. To do this, use either mono plugs or stereo plugs with the ring and sleeve bridged (pins 1 and 3 in the case of XLR connectors). Never use unbalanced XLR connectors (PIN 1 and 3 connected) on the MIC input connectors when using the phantom power supply.

Troubleshooting

Common issues with the Phenyx Pro PTX-15 include low audio levels, distortion, and connectivity problems.

To resolve low audio levels, check that all gain controls are adjusted properly and that the input sources are functioning correctly.
Distortion can be addressed by reducing the gain levels or using the EQ to balance the frequencies.
For connectivity issues, ensure that all cables are securely connected and not damaged.
Important instructions and warnings include avoiding overloading the mixer with too many high-gain sources, keeping the mixer away from moisture, and using the correct voltage specification to prevent damage.
