Improve the signal integrity and efficiency of your pedalboard with Buffer from Empress Effects, an all-analog I/O interface pedal that helps eliminate signal loss from long cable runs or unbuffered bypassing. Loaded with useful functions like an input pad and a series FX loop, Buffer helps you maintain a perfect tone.

A dedicated tuner output is provided, useful for a range of functions beyond keeping your tuner out of your signal chain. With the input loading adjustment, you can set your input impedance from 10 kilohms to 1 megohm depending on your pickup configuration. Constructed from die-cast aluminum, this rugged pedal can survive years of touring while maintaining a compact form factor that keeps your precious pedalboard real estate available.

With a three-way switch, you can pad or boost your input by 3 dB. This feature is great for matching outputs of different guitars, reducing overly hot active pickup signals, or boosting the signal going to your FX for an improved signal-to-noise ratio.

The separate tuner output is not only useful for keeping your tuner out of your FX signal chain, it can also be used as a secondary output for numerous applications. Use this second jack for stereo output, DI recording, or as a key signal for a noise gate or side-chain compressor.

The main goal of a buffer is to prevent signal loss, but some high-frequency roll-off from a long cable run may sound pleasing. When this side-mounted knob is fully clockwise, the full frequency range of your guitar signal passes through.

Turn the knob counterclockwise to start loading down your guitar, changing the response of your pickups, and rolling off just the right amount of high frequencies.

The Buffer can also act as 1-in / 3-out splitter. The input signal is normally routed to the loop out and tuner out.

When nothing is connected to the loop in jack, the input signal will also be routed to the amp out jack. This could be used to run multiple amps, or to record a separate dry signal when tracking, to use for reamping.

Q: 1. I understand that the MTK 12 and 22 record all channels via USB simultaneously, is this correct? So, then...is it 2.0 or 30. USB?

A: The Soundcraft Signature 12 MTK is able to route all input channels out via USB individually to a DAW. This connection is USB 2.0.

Q: 2. Can you use both the RCA in and USB connection to record at the same time? They are on the same channel, so it does not look obvious to me.

A: You can record the RCA input while connected to a computer via USB.

Q: 3. I make streaming for Instagram with mackie profx6v3 to Samsung s20fe (usb) . I can do this with soundcraft notepad 8fx?

A: Yes, the Soundcraft Notepad-8FX Small-Format Analog Mixing Console can be used in the same manner as the Mackie ProFX6v3 Sound Reinforcement Mixer.

Q: 4. Hosa Technology GPP290 Monaural Male 1/4" Phone to Stereo Female 1/4" Phone Adapter Can the above adapter be used to insert headphones into the adapter re the Zedi 10 FX's "aux out" quarter inch jack? Would this, notwithstanding the need for a converter, to convert line level signal to headphones level signal, work? If headphones are inserted into the aux out jack directly, the result is audio in the left ear only.

A: First, let's make clear that headphone signal is line level and headphone outputs typically use a stereo connector. The aux output on the Allen & Heath ZEDi-10FX is sending a mono line level output signal via a 1/4" TS (mono) jack, so that is why you only hear audio through the left side of your headphones when you connect the stereo plug to the mono output. The Hosa Technology GPP290 Monaural Male 1/4" Phone to Stereo Female 1/4" Phone Adapter (B&H # HOAPMSPF) will convert the stereo plug on your headphones to mono and that will allow you to hear mono audio through both sides of you headphones (same audio through both sides) when you connect the stereo headphones to the mixer's mono aux output. If you need to connect two sets of stereo headphones to the ZEDi-10FX, a better option would be to use a stereo splitter connected to the mixer's headphone output. The Hosa Technology 1/4" Male to Two 1/4" Female Y-Cable (B&H # HOYCSPM2SPF) will allow you to connect two sets of stereo headphones without sacrificing tone, volume or stereo separation. If you need to accommodate more than two sets of headphones, the best option is to use a separate headphone amplifier connected to the mixer's headphone jack. The Polsen HMA-41 4-Channel Stereo Headphone Amplifier (B&H # POHMA41) or the Mackie HM-4 4-Way Headphones Amplifier (B&H # MAHM4) are good options for this purpose. The headphone amplifier will give each user their own headphone jack as well as an individual volume control to set the volume level for their headphones fas desired.

Q: 5. I see full mix control for Str input 1 and mix control fot St 3. Is there no trim control for Str input 2?

A: Yes, there is no trim control for the ST2 input on the Allen & Heath ZEDi-10FX Compact Hybrid Mixer/USB Interface (with On-Board Effects Engine).

Q: 6. Does this board have Bluetooth ?

A: No

Q: 7. Is there a way to connect this to a computer via USB?

A: As the Yamaha MG06X 6-Input Mixer with Built-In Effects does not have built-in USB interface capabilities itself, an external USB interface would need to be implemented in between the mixer and the computer. An example of this type of interface is BH #FOSCARL2I23G Focusrite Scarlett 2i2 2x2 USB Audio Interface.

Q: 8. Is there anyway I can connect my cell phone to this mixer (an adapter or something) to receive phone calls for a podcast??? -PC

A: The best way to do a mix minus feature in this scenario is by using Dual 1/4 TS to one 3.5mm TRS Y cable. That will allow you to connect you smartphone to the mixer allowing you to receive phone calls for a podcast. https://www.bhphotovideo.com/c/product/846984-REG/Hosa_Technology_HMP_010Y_REAN_3_5_mm_TRS.html?sts=pi&pim=Y

Q: 9. When used with DAW to record tracks, what are the supported audio standards - 44.1/48/96khz? Is it 24 bit audio?

A: The bit rate is 24 bit, and sample rates are selectable at 44.1k or 48k.

Q: 10. Can you set up a mix minus with this unit for webcast use?

A: Utilizing the Aux output on this mixer, you could create a mix minus to send to phone interface or separate audio interface and return the callers audio back to an available channel on the mixer. Please note, this can not be done directly through the USB port on this mixer.
