Features
ACOUSTIC:CORE 30 is the result of countless hours of technical research and benchmarking against market-leading acoustic amplifiers. Designed from the ground up for acoustic players, they are straightforward, compact and designed for the way you play today: streaming, recording, practicing, or live.
Channel 1 features a 1/4″ jack input with GAIN, LOW and HIGH EQ controls with an ENHANCE select feature, which applies a studio-style EQ to give the feeling of space to your instrument sound. An independent REVERB level with two REVERB choices and a dedicated CHORUS level with two separate chorus effects, VINTAGE and WIDE in immersive Super Wide Stereo.
Channel 2 features a combination XLR / jack input with GAIN, LOW, MID and
HIGH EQ controls – perfect for a microphone or other instruments, and a VOCAL
CLARITY select which makes your microphone dynamically cut through the mix
with a more pronounced professional vocal sound.
A global PHASE button also allows you to control any unwanted feedback.
Your ACOUSTIC:CORE 30 acts as your USB Audio interface. By connecting a USB cable, you can simultaneously send both direct and processed audio to a computer for recording purposes, with a LINE OUT / HEADPHONE jack for output to a PA, recording desk, or headphones for quiet practice.
The LINE IN / STREAMING input allows you to connect your ACOUSTIC:CORE 30 to a
music device or drum machine to play along with. You can also use a suitable
TRRS 3.5mm cable for easy input / output Live Streaming with a compatible
device.
An integrated Tilt Stand is built in-to the base of the amplifier to allow you
to finely adjust the angle of your ACOUSTIC:CORE 30.
Front Panel
Channel 1
-
Input (1/4″ instrument jack)
Plug your acoustic instrument in here. Always use a good quality screened instrument cable. -
Gain
This controls the input gain of Channel 1. Turning it clockwise increases the input gain, increasing the volume. -
Enhance
This switch applies a studio-style EQ and spatial process to your instrument sound. With this switch in the OUT position the EQ is flat, providing a natural-sounding starting point for most instruments. The IN position engages an advanced DSP algorithm which gives a sense of space and depth to your sound. -
Low
The LOW control adjusts the amount of bass frequencies in your tone. This amplifier has active tone-shaping which allows the low frequencies to be precisely controlled for both the desired sound and also to help control instrument resonances. -
High
The HIGH control allows exact adjustment of the treble frequencies within your sound. At low settings (counter-clockwise) the sound will be warm and darker in character. As the control is increased (clockwise) the sound will become brighter and more lively. -
Chorus
This knob controls the two Super Wide Stereo Chorus effects; VINTAGE and WIDE. Each of these effects has an adjustable level within the segment. With the control fully counter-clockwise there will be no Chorus effect applied. Turning the control clockwise from the OFF position will increase the mix level of the VINTAGE Chorus effect, until the maximum VINTAGE Chorus level is reached with the control in the middle position. From the middle position onwards, the WIDE Chorus effect is controlled; at the fully clockwise position the WIDE chorus effect will be at the maximum level. -
Reverb
The Reverb control has two studio-quality Super Wide Stereo reverb choices, each with an adjustable level within the segment. With the control fully counter-clockwise there will be no Reverb applied. Turning this control clockwise to the middle position will increase the level of the ROOM Reverb. From the middle position onwards, the HALL Reverb is controlled. At the fully clockwise position the HALL Reverb will be at the maximum level.
Channel 2 -
Input 2 (combination XLR / jack)
Plug your microphone or another instrument in here. Always use good quality screened XLR or instrument cables. -
Gain
This controls the input gain of Channel 2. Turning it clockwise increases the input gain, increasing the volume. -
Vocal Clarity
The IN position applies a professional effect which allows your microphone to dynamically cut through the mix with a more pronounced sound. If your vocal sounds dark or too mid-focussed, engage this button to automatically enhance your vocal sounds. -
Low
The LOW control adjusts the amount of bass frequencies in your tone. This amplifier has active tone-shaping which allows the low frequencies to be precisely controlled for both the desired sound and also to help control instrument resonances. -
Mid
The MID control adjusts the amount of middle frequencies in your tone. The middle frequencies are particularly important in setting the amount of ‘body’ your tone has. -
High
The HIGH control allows exact adjustment of the treble frequencies within your sound. At low settings (counter-clockwise) the sound will be warm and darker in character. As the control is increased (clockwise) the sound will become brighter and more lively. -
Reverb
The Reverb control has two studio-quality Super Wide Stereo reverb choices, each with an adjustable level within the segment. With the control fully counter-clockwise there will be no Reverb applied. Turning this control clockwise to the middle position will increase the level of the ROOM Reverb. From the middle position onwards, the HALL Reverb is controlled. At the fully clockwise position the HALL Reverb will be at the maximum level. -
USB Audio Socket
This USB Mini-B socket is for connection to a computer via a suitable USB cable (not supplied). Standard audio drivers are used to connect the amplifier to a PC, Mac or other applicable recording device – no specific drivers are required.
For a guide on low-latency USB recording visit www.blackstaramps.com/usbrecording
NOTE: Always connect the amplifier via a main USB port, often found on the rear of the computer. The amplifier will appear as an audio capture device within recording
software.
The audio output via USB from your amplifier directly to your computer is carried across four independent, simultaneous channels:- USB Channel 1 + 2: A Stereo mix of your guitar and vocal channels, including Reverb and Chorus effects.
- USB Channel 3: A separate dry signal from channel 1 – this signal is taken after your EQ.
- USB Channel 4: A separate dry signal from channel 2 – this signal is taken after your EQ.
-
Master Volume
This controls the overall output volume of your amplifier. Turning it clockwise increases the volume. -
Phase
This will reverse the phase of the signal within the preamp. Use this to help to suppress acoustic feedback. -
Footswitch (not supplied)
The optional FS-18 footswitch, or any 2-way latching footswitch, can be connected here. The first switch on the FS-18 footswitch labelled ‘A’ toggles the Channel 1 Chorus effect on / off. The second switch, labelled ‘B’ toggles the Reverb effect on / off globally for both channels. -
Line / Headphone Out
This output provides a natural tone for connection to headphones, a recording device, PA system or mixing desk. -
Line In / Streaming
Play audio from your phone, MP3 player, tablet or laptop through the ACOUSTIC:CORE 30 using a stereo 3.5mm AUX cable (not supplied). Adjust the player’s volume to match that of your acoustic guitar to enable you to play alone
Use your ACOUSTIC:CORE 30 as an interface to play, live stream, practice and record on your mobile device. Unlike a standard audio 3.5mm TRS jack that only allows audio to be sent from your device, (e.g. to your headphones), the TRRS jack on your ACOUSTIC:CORE 30 allows audio to be sent and received at the same time. This allows you to playback audio from your device and send audio to your device from your ACOUSTIC:CORE 30. This feature allows you to use apps such as GarageBand and Instagram live with a single cable.
To use your ACOUSTIC:CORE 30 amplifier as
your Livestream Interface:
1. Connect your TRRS cable to your amplifiers Line IN / Streaming socket (see diagram above).
2. Connect the opposite end of the TRRS cable to your devices 3.5mm input.
NOTE: Apple iPhone / Tablet users: To connect to your mobile device, use
a Lightning to 3.5mm adaptor (It is advised to use an official Apple
manufactured cable / Adaptor for guaranteed compatibility)
3. Open an Audio recording software or Camera application on your phone.
4. Press record to test your levels are loud and clear. Use the channel
‘Gain’ controls on your amplified to set the level sent to your phone.
5. Test and adjust your channel controls and effects for optimum sound on
your Blackstar amplifier.
6. Record High quality videos, Audio memos and Livestream (direct to
Instagram Live, Facebook, YouTube, Twitch and more) straight from your
amplifier.

Power Switch
This switch is used to turn the amplifier on and off. The Power Indicator will be illuminated when the amplifier is switched on.
Rear Panel -
DC Input
The supplied detachable DC power supply is connected here. Always ensure the Power Switch (21) is in the OFF position before connecting the power supply. The power supply should only be connected to a power outlet that is compatible with the voltage, power and frequency requirements stated on the power supply. If in doubt seek advice from a qualified technician.
Optionally, your ACOUSTIC:CORE 30 can also be powered by Blackstar’s PB-1 PowerBank (not supplied). The PB-1 provides portable power for between 4-8 hours with your ACOUSTIC:CORE 30, depending on usage. -
XLR D.I Mix Output
This is a professional balanced XLR output for connecting directly to a mixer, stage box or front-of-house PA. This audio signal is a mix of both Channels, with Chorus and Reverb, and is not affected by the Master Volume. Use this output when playing live to send your mixed Guitar, Vocal and effects signals to a PA system.
Underside of the Amplifier
An integrated Tilt Stand on the base of the amplifier allows you to easily adjust the angle of your ACOUSTIC:CORE 30 for optimum projection of sound. Unscrew the stand to extend it for your desired angle. Please take care not to extend to the extreme length, as your ACOUSTIC:CORE 30 may become unstable and fall over.
