- Up to 18 hours of battery life
16 onboard adjustable effects
- Built-in compression on mono input channels and internal effects
- Assignable 9-band graphic EQ
2 Monitor Out busses

Input Channels

Mono channels feature Combi-Jacks that accept both low-impedance XLR and high-impedance 1/4'' balanced inputs. Stereo channels each have one XLR and two 1/4'' line-level inputs.

1. Microphone Inputs

The BPM12 accepts microphones with impedances ranging from 50 Ω through 10 kΩ. All low-impedance microphones are compatible. Most high-impedance microphones will work, provided that their XLR connection is wired with the audio signal on pin 2, and with pin 3 connected to pin 1.

Phantom power is available on all mic inputs, and can be turned on or off globally.

2. Line Inputs

Line-level signals can be connected to the balanced 1/4'' inputs on the mono or stereo channels. All mono channels have high-impedance 1/4'' inputs, which allow the direct connection of electric guitars, basses, acoustic pickups, and high-impedance microphones. Unbalanced sources can be connected using a standard unbalanced cable.

The two stereo channels will also work with mono signals, provided the source is connected to the L/Mono input. If a mono signal is connected to the R input on a stereo channel, it will only be heard in the right channel.

If you need more than two stereo channels, you can connect the left and right sides of a stereo signal to two mono channels. Adjust their pan controls fully to the left and right to preserve the stereo image.

3. Gain

The BPM12 features active channel input circuitry with exceptionally high audio headroom. The Gain control on each channel lets you boost signals by up to 72 dB.

4. Set/Clip and Clip LEDs

Each mono channel has a Set/Clip LED, and each stereo channel has a Clip LED. These indicate signal level and help ensure proper gain staging for the highest headroom and lowest noise. Clip LEDs will illuminate red when the signal is 3 dB below the channel's actual clipping level.

To set the input level for each channel, start by setting the channel fader to its lowest position the Gain control fully counter-clockwise.

For mono channels:

With the audio source playing, gradually turn the Gain control clockwise until the Set/Clip LED begins to flash green, indicating the optimal input level.

If the Set/Clip LED remains on continuously, it indicates that the channel compressor (described below) is active. Turning the Gain control counter-clockwise until the Set/Clip LED stops flashing will deactivate the compressor.

For stereo channels:

With the audio source playing, gradually turn the Gain control clockwise until it is at or just below the level at which the Clip LED occasionally flashes red during peaks in the loudest passages. Because the LED threshold is below the point of actual clipping, occasional illumination should not generally indicate audible distortion.

For all channels:

You can alternatively press a channel's Solo button to display that channel's pre-fader signal level on the VU meter in the master section. Adjust the channel's Gain control so that the LEDs corresponding to 0 VU illuminate on the loudest peaks.

Once the Gain control is set, turn up the channel fader to the desired level.

5. Compressor (Mono Channels)

Each mono input channel features a built-in soft-knee compressor. It controls dynamic range by reducing the volume of loud signals that exceed 0 dBV, resulting in a more consistent output level. The compressor works automatically in the background and only affects the signal as it approaches clipping level.

You can increase or decrease the amount of compression by raising or lowering the channel's Gain control. For more compression, set the Gain level so the Set/Clip LED flashes along to the input signal. At this point, the dynamic range of the source should be unaffected. Then, slowly turn the Gain control clockwise so the Set/Clip LED remains illuminated longer during peaks in the signal. If necessary, adjust the channel's fader to maintain a consistent level in the mix.

6. 100 Hz Filter

This switch activates a high-pass filter that rolls off frequencies below 100Hz with a slope of 18 dB per octave. The filter serves two important functions. Firstly, it can eliminate low-frequency noise and rumble to increase the clarity of your mix. Secondly, by removing low-frequency content from higher-register sources such as vocals, guitars, or wind instruments, these filters can create more space in the mix for lower-register sources such as the kick drum or bass guitar.

7. Mono Channel EQ

Mono channels feature a 3-band EQ. The Low and High bands are fixed at 80Hz and 12kHz , and the Mid frequency is variable between 150Hz and 5kHz . Each band offers up to 15dB of boost or cut, for subtle enhancements or dramatic changes. Please note that the wide range of the Mid Sweep control means that the Mid EQ may interact with the High and Low bands.

For live sound, you'll generally cut frequencies to solve mix problems rather than boost them, and the best approach is often to make the fewest possible adjustments. Subtle changes can reduce the risk of feedback when boosting, and preserve the character of each source.

8. Stereo Channel EQ

Stereo channels feature a 4-band EQ. Frequencies are fixed at 80Hz for the Low band, 400Hz for the Low Mid, 3kHz for the High Mid, and 12kHz for the High.

9. Mon 1 and Mon 2 (Monitor)

These controls can be used to create two separate monitor mixes. They adjust the signal level sent from each channel to the Mon 1 and Mon 2 faders in the master section and the corresponding outputs on the rear panel. The monitor sends are pre-fader, so you can freely make changes to the main mix levels without affecting your monitor mixes.

If feedback occurs, turning down the Mon 1 or Mon 2 faders can determine if the feedback is caused by microphones on stage picking up sound from the monitors. If that is the case, take the following steps:

1. Identify whether Mon 1 or Mon 2 is causing the feedback.
2. Turn up the corresponding fader in the Main section until feedback begins.
3. Turn down the corresponding Mon control on each channel to identify which channels are contributing to the feedback.
4. On channels which aren't causing feedback, return the monitor control to its original level.
5. On channels which are causing feedback, set the Mon control below the point at which feedback occurs.
6. If this doesn't fully eliminate feedback, you can also assign the graphic EQ in the Main section to the Mon 1 and Mon 2 mixes and attenuate each slider in turn until the feedback stops. Return any sliders which don't affect feedback to their original positions.

10. EFX

This controls the level of a post-fader send which is routed to the onboard digital effects, and to the EFX Send output for use with external processors. Signals from the channel EFX controls sum at the EFX Send control in the Main section.

If you don't require effects, you can also use the EFX controls as an additional monitor send. Please note that, unlike the pre-fader Mon 1 and Mon 2 controls, adjusting the channel faders will also change the mix at the EFX Send.

11. Pan and Balance

The post-fader Pan controls on mono channels and Balance controls on stereo channels adjust each channel's position in the stereo image of the main mix. Signals are compensated to maintain a consistent level across the stereo field.

12. Channel Fader

This controls the channel level. The fader taper is condensed at the upper and lower extremes, so you can quickly raise or lower volume, and expanded in the upper-middle area for precise adjustments.

13. Mute

This switch mutes its respective channel.

14. Solo

This switch solos the pre-fader audio of the selected channel in the VU meters and Phones output. This lets you easily set individual gain levels even while a full band is playing. The signal is taken before the Mute switch, so you can cue up audio sources in headphones before unmuting and adding them to the main mix.

Solo buttons on the BPM12 only affect the signal at the Phones output, so there is no risk of inadvertently disrupting your main mix.

15. Mute Zone

This switch will mute the channel in the mix sent to the Zone/Sub output on the rear of the mixer. See the "Zone/Sub" section for more details.

Main Section

1. Top Panel Connections

Connections for the EFX Send output, EFX Footswitch, 1/8'' Media In, and headphones are located to the right of the channel inputs for convenient access.

2. Phantom Power

This switch activates 24V phantom power globally across all microphone inputs. This is typically used to power condenser microphones, and will generally have no effect on other modern microphone designs. We recommend turning the phantom power off before connecting or disconnecting microphones to avoid loud pops.

Other compact mixers from Yorkville Sound, such as the PGM8 and VGM14, feature 48V phantom power to work with both live and studio microphones. We selected 24V for the BPM12 to preserve battery life, and because it is sufficient to power practically all live handheld microphones. If you want to use a mic that requires more than 24V, we recommend connecting it to an external preamp or power supply.

3\.Media In

For background music or other media playback, the BPM12 lets you connect stereo audio sources by 1/8'' TRS, USB-C, or Bluetooth®. The signal level from these sources to the main mix can be adjusted with the Media In control located below the stereo LED meters. The LED next to the knob will illuminate to indicate clipping.

4. Bluetooth® Receiver

The integrated Bluetooth receiver lets you wirelessly transmit audio from a computer or mobile device.

The receiver will be deactivated by default when the BPM 12 is powered on. To activate the receiver, tap the Bluetooth button in the upper right of the top panel, and the BPM12 will attempt to reconnect to the last connected source. To pair a new device, press and hold the button for 4 seconds.

A blue LED will indicate the current status of the Bluetooth connection as described in this chart:

LinkedLink-BackStandbyPairing
ON	ON, blinks 1x every 2 seconds.	Flashes 1x every 2 seconds	Flashes 2x per second

5. Power Only (USB-A)

This port provides a 5V / 1.5A power supply for charging a mobile device or connecting a USB lamp.

6. Media In/Out (USB-C)

This port lets you send digital audio from an external device for playback, or to an external device for recording.

The BPM12 can act as a class-compliant 2x2 USB audio interface, so no driver software is required. When connected over USB to a suitable host, the BPM12 can be completely bus-powered.

For the best performance, we recommend connecting the BPM12 with a high-quality shielded USB cable. If possible, the mixer should ideally connect directly to the host device rather than a hub. If a hub must be used, it should be a powered hub that is fully compliant with USB 2.0 or later.

Once the USB connection is made, you will need to select the BPM12 as the audio device on your computer or mobile device. Depending on your platform and operating system, it may appear as "USB Audio Device", "USB Audio CODEC", or something similar.

If you experience high latency, which is a delay between a sound being recorded to the host device and the playback audio coming back from it, this may be resolved by using a universal third-party audio driver.

7. Battery Status and Charging

The BPM12 has a four-segment LED bar to represent the battery level. Each segment represents approximately 25% of charge. When all four LEDs are illuminated, the battery will be at least 75% charged. A single red LED indicates that the battery level is critically low and the unit should be charged immediately.

To charge the BPM12, plug it into an AC or USB power source. When connected to AC, the Power LED will illuminate red to indicate the battery is charging, and green to indicate a full charge. The BPM12 can be used while charging, and features intelligent charging so it can remain connected to AC power indefinitely.

If the BPM12 will not be used for several months, we recommend charging it periodically to maintain battery health. If the mixer is stored for an extended period without occasional charging, we recommend plugging it in for approximately 24 hours before running the mixer on battery power.

The BPM12 will not charge when the temperature is below 0^ or above 45^

The BPM12 is delivered with 20 - 30% of the charge capacity. Please charge your unit for 5-hours prior to initial battery operation!

8. Graphic Equalizer

The stereo graphic equalizer offers 12 dB of boost or cut on each of the 9 adjustable bands. It can be assigned to either the Main or Mon 1/2 outputs using the button to the left of the sliders, and can be used to enhance the mix, compensate for room acoustics, or reduce feedback.

9. Internal Digital Effects (EFX)

The EFX Select knob lets you choose from 16 effect algorithms. These include multiple reverb, echo, and modulation options, as well as an acoustic guitar mode to enhance the sound of piezo pickups, and a harmonizer. A preset list is on the main panel to the left of the EFX Select knob for easy reference, and the Modify control lets you quickly tailor each effect to the performance.

Audio sent to the internal effects passes through a compressor to optimize the signal level. If the Clip LED next to the EFX Send knob illuminates, it indicates maximum compression. We recommend setting the EFX Send level at or below the point at which the Clip LED only illuminates occasionally during loud passages.

10. EFX Send Controls and Return to Main Fader

Audio from the channel EFX controls sum at the main EFX Send control. The summed signal is sent to both the internal digital effects and the EFX Send output, so you can simultaneously use the onboard effects and an external processor.

If using an external processor, please note that the BPM12 does not have a dedicated effect return. Connect the processor outputs to channel inputs on the mixer. EFX controls on those channels must be set fully counter-clockwise to avoid a feedback loop.

For the optimal signal level, turn the EFX Send control until the Clip LED at or just below the point at which the Clip LED to the left of the knob illuminates only occasionally during loud passages, adjust-

ing the EFX controls on the input channels if necessary. Press the Solo button next to the EFX Send knob to isolate the EFX Send signal in the LED meters and headphone output for ease of reference.

Use the EFX to Mon 1 and EFX to Mon 2 controls to adjust the level of the onboard effects in the monitor outputs, and use the EFX Return to Main fader to adjust the level of the onboard effects in the main mix.

The internal effects can be muted remotely by connecting a latching footswitch, such as an Apex AFS1 or equivalent, to the EFX Footswitch jack on the top panel. This footswitch will override the Mute button on the EFX Return to Main fader.

11. Mon 1 and Mon 2 Fader

Audio from the channel Mon 1 and Mon 2 controls sum at the Mon 1 and Mon 2 faders, which control the signal level sent to their corresponding outputs. Each monitor fader has a corresponding Mute and Solo button.

12. Phones

The Phones control adjusts the volume of the signal at the Phones output. This output will receive either the main mix signal or the signal from any active Solo switches.

The Phones output is compatible with stereo headphones that have a minimum impedance of 8 For the best performance, we recommend using headphones with an impedance of 30 or higher.

13. VU Meter

The VU meter indicates the post-EQ level of the left and right channels. We recommend setting levels such that the loudest peaks in the signal generally reach 0 dB on the meters. Occasional illumination of the yellow +3 and +6 LEDs is generally acceptable as long as you don't hear audible distortion. Illumination of the red +10 LEDs indicates the possibility of clipping and should be avoided.

14. Media In Level

The Media In knob adjusts the level going from the 1/8'' , USB and Bluetooth inputs to the Main fader.

15. Break Switch

Pressing this switch will mute channels 1 through 12, background audio can be played from the media inputs during program breaks, without any background noise from live mics on stage.

When the switch is engaged, the LED to the left of the switch will blink, along with the mute switches on the input channels.

16. Media Out

This knob controls the signal level going to the USB output. It is unaffected by the Main fader, so you can set an optimal recording level independent of any volume changes you need to make in the room.

17. Zone/Sub

This controls the signal level going to the Zone/Sub output. It receives a sum of the post-fader signals from the channel inputs, media inputs, and onboard effects. This can provide an adjustable mono signal for an additional loudspeaker or distributed audio system, with the convenience of a dedicated level control at your console.

Input channels and the onboard effects can be excluded from the Zone/Sub mix using their respective Mute Zone buttons. This can be especially valuable when using the output to drive a subwoofer, so that you can remove elements such as vocal microphones, and send only low-register instruments such as kick drum or bass guitar.

18. MAIN Fader

This fader controls the level of the combined signal from the channel inputs, media inputs, and onboard effects that is sent to the Main Out jacks on the rear panel.

Rear Panel

1. Power Switch, IEC and Fuse

The power button is on the rear panel between the IEC power socket and audio outputs.

The BPM12 uses a T500mAL (slo-blo) fuse. The fuse drawer is located on the IEC socket. If you suspect the fuse needs replacement, take the following steps.

1. Confirm that there is 100-240V~ power at the outlet to which the BPM12 power cable is connected.
2. Confirm that the power cable is firmly connected to the BPM12 and the power switch is turned on.

3. If the Power LED on the BPM12 does not illuminate when the Power button is in the On position, turn the mixer off and disconnect the power cord from the unit.

4. When the power cable is removed, you will be able to see a small slot on top of the fuse drawer. Insert a small screwdriver into the slot and gently apply pressure to slide the fuse drawer out of the mixer.

5. The fuse drawer can hold two fuses. The fuse in use is in a clip on the side of the drawer that is inserted into the mixer. The sides of the fuse will be exposed when in the clip. A spare fuse can be kept in the rectangular compartment on the opposite side of the drawer. Remove the fuse in use from the clip to inspect it. If the filament in the fuse is broken, the fuse must be replaced. It is imperative that you replace it with the same fuse type.
6. Slide the fuse drawer back into the BPM12, reconnect the power cable, and turn on the mixer. If the new fuse also blows, then your BPM12 may require service from an authorized technician.

2. Line Outputs

XLR and 1/4'' connectors for the Zone/Sub, Main L/R, and Mon 1/2 outputs are located on the rear panel. These are balanced, low-impedance outputs, and we recommend using high-quality shielded cables for the best audio performance.
