INTRODUCTION
Caution:
We want to emphasize that prolonged exposure to high volume levels can
damage your hearing, as well as your headphones or loudspeakers. Always turn
the MAIN MIX and PHONES controls fully counterclockwise before powering on
the unit. Adjust volume levels carefully to avoid damage.
Important Notes About Installation
The sound quality of the device may be aected by powerful broadcasting
stations or other high-frequency sources. To minimize interference, increase the
distance between the transmitter and the device, and use shielded cables for
all connections.
General Functions of a Mixing Console
A mixing console performs three key functions:
1. Signal Processing:
• Preamplication
• Level adjustment
• Eects mixing
• Frequency equalization
2. Signal Distribution:
• Summing signals to aux sends for eects processing and monitor mixes
• Routing to one or more power ampliers, control room outputs, and 2-track
outputs.
3. Mixing:
• Adjusting volume levels
• Equalizing frequencies
• Positioning individual signals within the stereo eld
• Controlling the overall mix level to suit recording devices, crossovers, or
power ampliers
Before You Begin
Shipment
Your mixing console has been carefully packaged to ensure safe transport.
However, please inspect the packaging and contents for any signs of physical
damage that may have occurred during transit.
If you nd any damage, do not return the unit to us. Instead, contact your dealer
and the shipping company immediately. Claims for damage or replacement
may not be honored if these steps are not followed.
Initial Setup
To ensure proper operation and prevent overheating, make sure there is
adequate space around the unit for cooling. Do not place the mixing console
near high-temperature devices like radiators or power ampliers.
• Connect the console to the mains using the supplied power cable.
The unit meets all required safety standards. If a fuse blows, replace it only
with one of the same type and rating.
• Important: Never connect the mixer to the power supply while the power
supply is connected to the mains. Always connect the power supply to the
console rst, and then connect it to the mains.
• Ensure all units are properly grounded. For your safety, never remove or
disable ground connectors on electrical devices or power cables.
• Installation and operation should only be carried out by qualied personnel.
The user must maintain sucient electrical contact with the ground to prevent
electrostatic discharge from aecting the unit’s performance.
4. [GAIN] Control
• Adjusts the basic volume of each channel for optimal performance.
• If the [PEAK] LED lights up, reduce the gain by turning this control counter-
clockwise.
5. [HIGH] Treble Control
Adjusts the high-frequency (treble) tones, allowing enhancement or
attenuation of up to ±15 dB at 12 kHz.
6. [MID] Midrange Control
Adjusts the midrange tones, allowing enhancement or attenuation of up to
±15 dB at 2.5 kHz.
7. [LOW] Bass Control
Adjusts the low-frequency (bass) tones, allowing enhancement or attenuation
of up to ±15 dB at 80 Hz.
8. [FX] Control
• Adjusts the signal level sent from the channel to the FX/reverb line.
• For stereo channels, signals from the left (L) and right (R) inputs are mixed
before being sent to the FX line.
9. [PEAK] LED Indicator
• Flashes when the input signal or equalized volume is too high.
• To resolve this, reduce the gain by turning the [GAIN] Control counterclockwise.
10. [LEVEL] Control
Balances the volume of each channel within the overall mix.
MIC INPUT
Each mono input channel includes a balanced microphone input via the XLR
connector, with a switchable +48V phantom power supply for condenser
microphones.
• The preamps deliver clean, distortion-free gain, comparable to high-quality
external preamps.

CONTROL ELEMENTS AND CONNECTORS
This chapter provides a detailed overview of the control elements of your
mixing console. All controls, switches, and connectors are explained below.
CHANNEL INPUT
1. [MIC/LINE] Mono Input: Connect a microphone, musical
instrument, or audio device (e.g., CD player) to this input.
Supports both XLR and unbalanced 1/4" plugs.
2. [+48V PHANTOM] Button/LED
• Activates the DC +48V phantom power for XLR plugs on the
MIC/LINE mono input.
• Turn on this button when using a condenser microphone
requiring phantom power.
• When activated, the LED indicator will light up.
3. [PAD] Button
• Attenuates the input signal when turned ON.
• Use this switch if you hear distortion or if the [PEAK] LED
indicator lights up.
XLR UNBALANCED 1/4 " PLUG
www.PyleUSA.com10 www.PyleUSA.com 11
• Important: Mute your playback system before activating the phantom power
to avoid loud thumping noises in your loudspeakers.
LINE INPUT
Each mono input channel also features a balanced line input on a 1/4" connector.
Unbalanced devices (mono jacks) can also be connected to these inputs.
Note:
You can use either the microphone input or the line input on a single channel,
but not both simultaneously.
GAIN CONTROL
The [GAIN] Control adjusts the input gain for the connected signal source.
Always turn the control fully counterclockwise before connecting or
disconnecting any device to avoid sudden volume spikes or damage.
FX (Eects) Control
The FX send (or AUX send) allows you to send signals from one or more
channels to an eects device.
1. The signals are summed to an FX bus, which appears at the console’s FX Send
Output.
2. From there, the signal can be sent to an external eects unit, and the
processed signal can be returned to the console through the aux return
connectors or regular channel inputs.
Features of FX Control:
• Each FX send is mono and provides up to +15 dB of gain.
• Congured post-fader, ensuring the mix of the dry signal and eects remains
consistent with the channel’s FX send settings, even when the level knob is
lowered.
• This setup ensures eects are muted when the channel's level is turned down
completely.
MAIN CONTROL
This section describes the primary controls, connectors, and functions of the
mixer.
4. Level Indicators:
Show the signal levels from the [STEREO OUT] outputs.
• If the [PEAK] indicator lights up in red, reduce the output level by adjusting
the [LEVEL] Controller.
5. [LEVEL PHONES] Earphone Volume Controller: Adjusts the volume for the
connected headphones.
6. [STEREO LEVEL] Fader:
Controls the overall volume of the [STEREO OUT] output signal.
7. [SEND] Level Controller:
Adjusts the signal level sent to the [SEND OUT] socket.
8. [RETURN] Level Controller: Adjusts the volume of the return signal from an
external device connected to the [RETURN] Input Socket.
1. [PROGRAM] Controller: Select from 16
internal digital eects. The selected eect
signal is applied equally to both the left (L)
and right (R) stereo outputs.
2. [REPEAT] Echo Controller: Adjust to set
the desired level of internal echo for the
eects signal.
3. [FX LEVEL] Eects Return Level Controller:
Controls the volume of the eects return
signal.
