Mixer Layout and Controls

Front Panel of Pyle Multi Channel Mixer PMX840BT

3-PIN LOW IMPEDANCE MIC INPUT
- Electronically balanced XLR input is designed to accept signals from any balanced or unbalanced low impedance (Low Z) microphone. (Pin 1 to the shield, Pin 2 to the 'hot' (positive polarity) side of the audio signal, and Pin 3 to the 'cold' side of the signal). Dynamic or ribbon-type microphones do not require phantom power. Microphone inputs are generally more sensitive than the Line inputs.
1/4'' LINE INPUT
- Line/High impedance input, 1/4” connector jack is designed to accept balanced or unbalanced line-level signals such as those from keyboards, drum machines, or samplers. There is enough gain available on the line input to accept even lower level signals, such as those from an unbalanced microphone or guitar output. If a balanced signal is to be connected to the line input, then a 1/4” TRS (stereo) phone plug should be wired for: Tip = positive (+), Ring = negative (-), Sleeve = ground.
GAIN CONTROL
- Adjust the volume for the selected channel's signal. It sends the signal to the master mix buss. Please remember this function allows the unit to act as a pre-amp, so if you are using a device that has its own unique volume control, you will need to perform some volume adjustment and level matching. Optimal sound performance is achieved when audio distortion is at a minimum.
EQ CONTROL - INDEPENDENT CHANNEL
- Independent channel selection allows equalization effect controls for the input signal. This gives you the ability to adjust the overall tone of the selected input. It acts as a cut or boost control, that adds to or diminishes the sound quality - 60Hz - 10kHz (+/- 15dB).
EFFECT CONTROL - INDEPENDENT CHANNEL
- Also known as EFFX controls, this is a 'send' control to the reverb buss. It controls the amount of reverberation added to the selected destination channel input signal.
LCD DISPLAY - USB/SD CONTROL
- Use the digital LCD control panel and touch button to control your connected flash memory drive. Take music from your computer's media library, transfer it to your removable memory storage device and let it play through the mixer. Supports MP3 and WMA music formats.
EFFECTS CONTROLLERS
- Take control of the Effects Volume, Effects Echo, and Effects Delay. Control the overall signal level of the effects 'mix' that is received. Delay and Echo controls allow you to variably adjust the effect interval time. Set this control lower for shorter Echo times to emulate similar 'doubling' effects while setting a higher level provides longer effect times for 'stadium-like' delay sound.
USB/SD VOLUME CONTROL
- Adjust the volume for connected media streaming via USB Flash Memory or SD Memory Cards.
MASTER VOLUME CONTROL
1. Adjust the volume for the entire mixer and connected devices playing through the mixer.
MASTER GRAPHIC EQUALIZER CONTROL
- (Low - Low/Mid - Mid - Mid/High - High), these master EQ controls allow you to adjust the levels of signal frequencies. 5-Band frequency graphic EQ faders put you in control and allow you to achieve optimal sound performance. Adjust the faders accordingly with different acoustic and environmental conditions.
POWER LED
- This LED will illuminate when the unit is switched on.
AUX (3.5mm) INPUT
- Auxiliary input connector jack for connecting devices like MP3 Players, Smartphones, Tablets, etc.
CD/TAPE: INPUT
- Use the RCA (L/R) input connector jacks to connect a stereo signal output device to the mixer. (CD, Tape, Cassette, MP3, Smartphone, Tablet, Mac, PC, Laptop, etc.)
REC: OUTPUT
- This signal RCA (L/R) output connector jacks are for connecting an external device to record from the mixer. Both channels are conformed into mono for compatibility. The signals are then taken 'pre-master' meaning the signal is without reverb or the master tone section does not include the tape signal. The connected signal becomes the 'main' bus signal before passing through the mixer's 'master' level controls and graphic equalizer. (Impedance: 1k Ohm @ -10dB)
INPUT VOLUME CONTROL
- This control adjusts the level of the input signal applied to the CD/TAPE Input.
Back Panel
AC POWER
- The power supply cable is the standard voltage for US AC wall outlets. It is grounded and should never have the ground pin removed for any reason.
SPEAKER OUTPUTS
- 1/4'' speaker outputs (A/B). Standard 2-conductor phone jacks are wired in parallel, with each having the ability to connect to your speaker system.
EFFECT LOOP
- Return: Mono unbalanced 1/4'' connector jack for incorporating return effect or other line level source. It brings the output of the external effects device back into the mixer for further processing. (Impedance: 10K Ohms @ -10dB).
- Send: Mono unbalanced 1/4'' 2-Conductor line outputs. Used to connect additional recording device or external effects processor. Applies to the input of an external effects unit and allows you to 'send' your dedicated signal out to the connected external device. (Impedance: 1k Ohm @ -10dB).
POWER SWITCH
- Control the power of the unit ON/OFF. When the unit is powered on, the LED indicator light on the front will shine blue.

Description

Pyle Multi Channel Mixer PMX840BT is a versatile and feature-packed mixer designed for professional audio applications. With 8 channels, each with its own 3-band EQ, this mixer provides a high level of control over your audio signal. The Bluetooth connectivity allows you to wirelessly stream audio from your phone or other device, making it easy to incorporate backing tracks or other audio sources into your mix. The built-in USB interface makes it easy to record and playback audio tracks, and the headphone output with its own level control ensures that you can monitor your mix at any volume.

Installation

Install the mixer on an even surface to allow for sufficient airflow and ventilation during use. The device is equipped with electronically controlled cooling fans to protect against thermal overload and internal circuitry from damage due to extreme heat. Please avoid covering any sides of the unit or placing objects or other audio devices too close to your mixer. Prior to connecting and powering on the unit, make sure that the device matches the voltage and frequency of your power supply. Power off the mixer when not in use.

Cables and Connections

RCA

RCA connector jacks have been most commonly used in home audio systems and configurations for years. Also known as RCA 'phono', 'plugs' or 'audio connectors', these jacks are always unbalanced and generally carry a line-level signal at –10 dB nominal signal levels. The RCA connector jacks are most likely used when connecting an audio device like a media player or other home audio-type source to your mixer. These connector jacks are also used when connecting to the output of your devices.

1/4'' TRS and Mono

1/4'' mono and stereo connector jacks are labeled for use as unbalanced mono, unbalanced stereo, balanced mono, or as an insert patch point. A 1/4'' TRS (Tip, Ring, Sleeve), 3-conductor connection, or 'Stereo' cable allows a single connection signal to carry 2-channels of audio; it can also be used for mono balanced signals. Meanwhile, a 1/4'' TS (Tip, Sleeve), 2-conductor, or 'Mono' cable is most popularly known for its use in guitar or line-level instrument connections; it can also be used for mono unbalanced signals.

XLR 3-Pin XLR

connector jacks almost always carry a balanced signal. Depending on your device, these connector jacks may also be capable of handling unbalanced signals. Microphones generally have this type of connector, as well as most other professional audio equipment and devices. Typical 3-Pin XLR sockets are fixed with the right-most pin being the 'ground', the left-most pin being 'hot', and the bottom pin as the 'neutral'.
