Basic Operation
The XENYX 1002B is easy to use. Simply follow these steps to achieve the best possible sound:

Plug the included power cable into the back of the mixer. Plug the other end of the cable into a mains outlet. DO NOT turn the mixer on yet.
Make all appropriate audio connections:
- Connect microphones to the MIC jacks using XLR cables.
- Connect line-level sources to the LINE IN jacks using ¼” TS cables.
- Connect stereo sources (keyboard, drum machine) to one of the stereo LINE IN jacks using a pair of ¼” TS cables.
- Connect a CD player to the 2 TRACK INPUT using ¼” or RCA cables.
- See Applications chapter for more details and options.
Connect a monitoring source or speaker system. You may connect powered studio monitors, powered loudspeakers or a power amp to the MAIN OUTPUT jacks. You may also connect a pair of headphones to the PHONES jack. Leave powered speakers and/or power amps turned off until the mixer has been powered on.
Turn all PAN/BAL and EQ knobs to their center (12 o’clock) position. Set all other knobs and faders all the way down/off.
Once all connections have been made, you may turn the mixer on.
After the mixer is turned on, you may also turn the speakers or power amp on.
Set the input gain level for each channel using the GAIN knob. While testing the audio source, turn the GAIN knob as high as possible without allowing the CLIP LED to light. See the Gain Setting section for details.
Raise the MAIN fader to 0. You may adjust it further as you begin to set levels.
Adjust all channel volume faders until you achieve a balanced mix.
Make sure that the channel CLIP LEDs and MAIN CLIP LEDs do not light frequently. If this happens, adjust the respective GAIN or MAIN fader accordingly.
Congratulations! You have now set up a basic mix! The 1002B offers many other cool features as well, so continue through the manual to make the most out of this powerful little mixer.

Gain Setting

It is very important to set each channel’s GAIN knob correctly in order to get the maximum amount of signal headroom and least amount of noise possible. Setting the GAIN too low could make that channel too quiet to mix properly, while setting it too high will cause clipping and distortion. Stereo channels 3/4, 5/6 and 7/8 allow the MIC and LINE inputs to be used in parallel thanks to the dedicated GAIN knobs for each input. Follow these instructions to set the gain for each channel and situation:

Plug the audio source into the channel input (XLR or ¼”).
Sing into the microphone or play the line-level source at the volume you will ultimately use during recording or performance. If you set the gain for a vocal mic by saying “check” into it, this gain setting will probably not be as loud as the actual vocal performance. Setting the gain this way will lead you to set the gain too high, which may cause the extra loud vocal performance to overload and distort. Likewise, if checking a mic that will record a saxophone, make sure the performer plays close to the mic while setting the gain. For keyboards, do not change the output volume of the keyboard after the mixer’s gain has been set.
Turn the GAIN knob clockwise until the red CLIP LED lights up. This means the channel has begun to overload (too much signal is allowed in).
Turn the GAIN knob counterclockwise a small amount, then sing or play again. Ideally, the GAIN knob should be set as high as possible while allowing the CLIP LED to only light occasionally, if at all.
If you must use both the MIC and LINE inputs on channels 3/4, 5/6, or 7/8, you can adjust the gain setting for each source individually thanks to the dedicated GAIN knobs. The channel fader affects the level of both sources, so achieving a good balance between the 2 inputs can be tricky.
Set the gain for the MIC input using the GAIN MIC as described above.
Set the gain for the LINE input(s) using the GAIN LINE as described above.
Both GAIN knobs share the same CLIP LED, so when both sources are in use at the same time, neither input should cause the LED to light. If this happens, turn each GAIN knob down one at a time to determine which is overloading.
Raise the channel fader so that both sources are audible in the overall mix. Ideally, they will already be balanced and not require further adjustment.
If one source is too quiet with the fader turned up, turn the louder source’s GAIN knob down a bit, then raise the fader to the appropriate level. DO NOT simply turn the quiet source’s GAIN knob up until it is loud enough, as this will likely cause clipping and distortion.

Using External Effects
The 1002B lets you use external effects processors to add a touch of reverb, delay, or other effects to various channels. Use the channel FX knobs, FX SEND knob and FX SEND jack to send a portion of the signal from several channels to an effects processor. You can insert the “wet” signal back into the mix through one of the stereo channels. The FX signal from each channel is sent “post-fader,” meaning that as you change the channel’s volume, you also change how much of that channel’s signal is sent to the effects processor. This ensures that the mix of wet and dry signal remains the same as you adjust the channel volume. Follow these steps to incorporate external effects in your mix:

Connect a ¼” TS cable from the FX SEND jack to the input of the effects processor.
If you would like the effects to operate in stereo, connect ¼” cables from the left and right outputs of the processor to one of the stereo input channels on the 1002B.
For mono operation, most processors return a mono signal through the left output. This mono signal should then be routed into the left input on one of the mixer channels. If possible, use channel 9/10 since it only allows line inputs.
Turn the FX SEND knob to the center (12 o’clock) position.
Turn the channel FX knob up for each source to which you would like to apply effects. For example, you can add a lot of reverb to a vocal mic, while only adding a small amount to a snare drum. This will just be a preliminary setting as you will not be able to hear the effect yet. Keep the knobs around the center position; you will fine-tune them shortly.
Adjust the input gain for the channel receiving the output from the effects processor. (See the Gain Setting section for details.)
Turn the channel fader up to 0 on the channel receiving thesignal back from the processor. DO NOT turn the FX knob on that channel up at all! Your sound system will become haunted with screaming banshees.
You should now hear the selected effect on the channels that are sending signal to the processor. Adjust the channel FX knobs to get the effect mix just right.
NOTE: The processor will likely have its own VU meters to monitor the incoming signal level. If the processor’s meter begins clipping, turn down the FX SEND knob on the 1002B. See the Applications section for details.

Creating a Monitor Mix

For live applications, audio engineers often send different mixesto the audience and to the performing musicians. To allow this, the 1002B is equipped with a dedicated monitor send bus. Each channel features a MON knob that sends a “pre-fader” signal to the MON OUT jack, allowing the channel’s volume fader to be adjusted without affecting the monitor mix. The signal can also be used as a second effects send. Follow these steps to set up a basic monitor mix:

Make sure the powered monitor speaker or power amp is turned off. Connect a ¼” TS cable from the MON OUT jack to the powered speaker or power amp.
Turn on the powered speaker or power amp, and then turn the volume up about half way.
Turn the MON SEND knob to the center (12 o’clock) position. This setting may need to be adjusted later depending on volume requirements.
As the musicians begin to play, turn each channel’s MON knob up slowly until each source is audible in the monitor mix.
It may take some time to get a balanced mix that all the musicians are happy with. If possible, avoid turning a channel’s MON knob much past the center position. Do not point the monitor speakers directly at a microphone, as this will likely cause feedback. See the Applications section for details.

As previously stated, the MON SEND jack can also be used as a second effects send. This application requires a similar setup to the normal effects send, but since the signal from each channel is sent pre-fader using the MON knob, adjustments to the channel’s volume will affect the mix of wet and dry effect signal. Therefore, if you alter a channel’s volume during the performance, you must also adjust that channel’s MON knob.

NOTE: When using the MON SEND for effects, if you neglect to change a channel’s MON knob while turning that channel’s volume fader all the way down, you will still hear the effected signal coming through the mix. This problem happens because the signal routes “pre-fader,” but the normal FX SEND bus will not experience this issue.

Battery Installation
The 1002B can be powered by three 9V batteries. This feature allows you, for example, to capture a high-quality recording while sitting on the beach with your laptop. You’re no longer tethered by an electrical outlet. You can still record with condenser mics thanks to the 18V of phantom power supplied by two of the batteries. Follow these steps to install the batteries:

Open the battery compartment located on the underside of the mixer. You will need to remove a small screw with a Phillips screwdriver.
Slide the compartment cover out. There are slots for three batteries inside the compartment.
Insert the batteries so that the + and – poles are in the correct position.
Replace the cover and tighten the screw.
The battery power will last approximately four hours using highquality alkaline batteries.
