1.2 SC2-Plus Front-Panel Controls

CLICK MONITOR

Push on, push off: when

the LED is lit, SugarCube is

processing audio to remove

clicks and pops (the BYPASS

LED will go out.)

CLICK REMOVE ‘IN’

When pressed and the LED is lit, the
SugarCube suppresses the music so
that you can better hear the clicks and
pops. This helps set the STRENGTH
level for particularly noisy LPs.

STRENGTH

Headphone amp operates
independently and does not
affect the level of the line
in / out audio.

BYPASS

When pressed and the LED is lit,
an internal relay has shunted the

LINE-IN directly to LINE-OUT,

bypassing all internal circuitry.

Controls the strength of the click
and pop detection and removal
process. Almost all LPs will sound
great at a setting of 5 or 6.

Note: we recommend that you do
NOT adjust STRENGTH all the
way to 10, you will rarely need
this much. Less is more.

Connecting to an integrated amplifier via Aux In/Out (or Rec In/Out).

1. Connect AUX OUT (or REC OUT) of your integrated amp (or processor) to the LINE IN of the SC2-Plus.

2. Connect LINE OUT of the SC2-Plus to AUX IN (or REC IN) of your integrated amp or processor.

NOTE: DO NOT CONNECT THE LINE OUT OF THE SUGARCUBE TO THE PHONO INPUT ON YOUR EQUIPMENT.

Step 1: TURN OFF THE INTEGRATED AMP

Step 2: Wait a minute or two

Step 3: locate the preamp-power amp jumpers

Step 4: DOUBLE-CHECK THAT THE AMP IS OFF

Step 5: Remove the jumpers

Step 6: Put the jumpers away in a safe place

Step 7: NEXT PAGE...

2.4 Connecting Your SugarCube

Integrated Amp: connecting between the preamp and power amp, cont.

1. Connect OUTPUT (this is the pre-amp) of your integrated amp to the LINE IN of the SugarCube.

2. Connect LINE OUT of the SugarCube to PWR AMP (power amp input) of your integrated amp.

3. ALWAYS TURN ON THE SUGARCUBE FIRST THEN THE AMP AND TURN OFF THE AMP FIRST

THEN THE SUGARCUBE.

4. If the integrated amp has a headphone output, it will likely have its own amplifier and may not be in
the loop with the SugarCube. If that is the case, you will not hear the SugarCube in the headphones.

5. The SugarCube draws only about 11 watts, you can leave it on full time if you wish.

6. Not all integrated amps have a line out / power amp in or an Aux Out / In. If this is the case, you

may need an external phono pre-amp.

2.6 Connecting Your SugarCube

Integrated Amp WITHOUT an AUX OUT/IN (or REC OUT/IN, etc.)

Many contemporary integrated amplifiers no longer have what was known as

a ‘tape loop’ (back in the day of the cassette and reel-to-reel tape). Also,
most modern home theatre processors that do have what are called ‘effects

loops’ will not send audio from its phono input through the loop. In these

cases, there is not a way to connect to SugarCube directly to these devices
while using its built-in phono stage.

The solution is to add a phono stage (pre-amp) between your turntable and
the SugarCube. Then connect the Line Out of the SugarCube to any available
input on the integrated amp (except for the phono input, of course.)

2.7 Connecting Your SugarCube

1. Connect the turntable with a built-in phono pre-amp to LINE IN.

2. Be sure the turntable is set to LINE not PHONO.

3. Connect the LINE OUT of the SugarCube to any line-level input of
your line stage, pre-amp, or integrated amp.

NOTE: SORRY TO BE A BROKEN RECORD, SO TO SPEAK, BUT DO NOT CONNECT THE
LINE OUT OF THE SUGARCUBE TO THE PHONO INPUT ON YOUR EQUIPMENT.

Directly connecting the line-level output from your turntable.

For turntables with a built-in
phono pre-amp, be sure to set
the PHONO/LINE switch to

LINE before plugging into the

SugarCube.

When you power up your SugarCube, it will take about

three minutes to complete its startup procedures.

During this time, the display will light up but remain
blank. We apologize for the wait but we have some
seriously sophisticated software loading and it simply
takes additional time. When you hear the results of
our efforts, you will agree that it was worth the wait.

2.8 Starting Up Your SugarCube

Please note:

(1) SugarCube just powered on (2) SugarCube is ready to go

(please expect about three

minutes to ready.)

(3) Hold the ‘Bypass’ button for a

few seconds to see LAN address

DAC at any sample

rate.

In External mode, the SC2-Plus acts like any other studio-quality ADC/DAC pair and will function at any standard sample

rate and bit depth from 192k down to 44.1k and at 16/24/32 bit sample sizes.

Note: Please press again the button of the current mode of operation if the external device loses lock with the

SugarCube (you will certainly know due to obvious digital noise.) This resets the internal timing and restores the audio.

General Info

FAQ

Some common questions

& answers about using

the SC-Plus series

Basic connectivity

• Q: Line-In level setting, why so many choices?

• A: You can select four steps each 6dB apart to accommodate low- to high-level output

equipment. Whatever level you select for input is mirror the opposite way for output (i.e.--

choosing -6dB line in results in +6dB applied to line out so line in always equals line out.)

• Q: What is bridging?

• A: This is an analog routing mode where line in goes directly to line out through the

bypass relay just like in Bypass mode but is tapped at a high impedance (about 100k ohms)
and passed through the internal analog-to-digital converter and then sent out to whatever is
attached to the SC2-Plus digital interface. The attached computer can operate at any sample

rate or bit depth in this mode.

• Q: How do I connect through tape loops?

• A: Tape Out goes to the SugarCube Line In and the SugarCube Line Out goes to Tape

In. Sometimes the tape loop is labeled Aux or Rec but is the same thing.

• Q: How do I connecting an external computer?

• A: The SC1-Plus appears as a standard ADC/DAC to a connected PC, Mac, or music

server. No special drivers are needed.

• Q: My computer only goes to 48k, how to I fix that?

• A: You can always use the SC2-Plus as an ADC/DAC at 48k but you cannot then use the

SugarCube internal functions. You will need to disconnect the computer when you wish to
use the SugarCube with your turntable.

Repair modes

• Q: when I use the noise reduction, do I have to start at the lead in groove or can I play any
track on the record?

– A: This is a yes and no answer: for the first time you play any record using noise reduction (NR),

you must start the noise reduction process then drop the needle on the lead in groove.

– A: Then, if you do not stop the process (that is leave it running), if you are playing, for example, a

box set of records from the same album or a double album, the “fingerprint of the noise that the
SugarCube created stays in memory and, as long as you don’t turn off the SugarCube, you can

drop the needle anywhere or play other side without having to drop the needle in the lead in
groove. The NR process will continue to work perfectly.

– A: Furthermore, you can extend the above concept if you have LPs from the same label and era

(example: late-1950’s Blue Note), the noise “fingerprint” that the SugarCube picked up on the first
side of the first LP will work for all other LPs of your Blue Note collection when you use NR.

– A: However, if you play an LP from say, EMI, that label used a different vinyl plastic formula in

making their LPs so their (EMI’s) noise “fingerprint” will be quite different and will require stopping

the NR process and re-starting then drop the needle once again in the lead in groove.

– A: Finally, you could use NR and only one time drop the needle for a “fingerprint” then never do it

again, NR will still work but it will be far from optimal and there will be a drop in volume.

– A: Bottom line: NR is a very powerful tool that can do an amazing job of lowering noise in

recordings. It is well worth your time to start and stop NR when the LP is different.
