Quilter Superblock Compact Guitar AMP

CONGRATULATIONS!
Welcome to the SUPERBLOCK-US: Micro size, major TONE!

The SUPERBLOCK provides all the key requirements for coupling an electric guitar or other instrument to a PA or recording console, and also contains a built-in amp with 25 “real watts”, enough power for practice or small gigs. It combines a full-service guitar preamp, overdrive section, effects loop, cabinet simulator, headphone driver, and highly dynamic 25-watt power amp in a single pedal-size enclosure. It provides a complete interface for your instrument, your pedals, your DAW, your PA system, or a stand-alone loudspeaker, with the flexibility to handle whatever you may need as a performing artist. In spite of its diminutive size, this little powerhouse packs a potent punch capable of driving a serious stageworthy rig.
The high impedance INPUT accepts normal guitar cables. The GAIN control ranges from clean to overdrive. The LIMITER acts like a “governor” affecting the higher ranges of gain response. The three band EQ adjusts LOW, MID, and HIGH frequencies, with three selectable EQ VOICE modes based on famous US-made amplifiers. A series FX LOOP includes a “stealth input” that allows an auxiliary music source to be “injected” into the FX RETURN, which further expands the capabilities of the SuperBlock. The MASTER control adjusts the overdrive threshold from 0 to 25 watts offering clean headroom and/or rich overdrive at will. From the MASTER CONTROL, dual signal paths lead to the BAL LINE OUT/HEAPHONE jack, and the SPEAKER OUTPUT jack, which drives any normal speaker, and is stable with no speaker connected.
Please consult the rest of this manual to obtain the best results from all these features.

A NOTE FROM PAT QUILTER:
Our goal at Quilter Labs is to bring you all the tone and dynamics of the best vintage amplifiers without the weight and drawbacks of tube technology.

Troubleshooting Chart:

NO SOUND| RED POWER LED IS ON: Confirm that Power switch is ON (not STBY). Confirm that the Gain, Master and your instrument volumes are turned up. Confirm that input, effects loop, and speaker cables are all good.

Try an alternate speaker, and try the headphones to see if you have signal.

NO RED POWER LED: Check the PS-24 power supply.

If the green power supply LED is on, confirm that the connection from PS-24 power supply to SUPERBLOCK is fully seated.

If the green power supply LED is off, confirm that the AC power is plugged in. If so, unplug the power supply from the SUPERBLOCK. If the green LED comes on, the SUPERBLOCK may be bad. If the greed LED stays off the pow- er supply may be bad. Contact Quilter Labs for service instruction.

If the sound from the SUPERBLOCK remains weak and garbled, it may need

servicing.

HUM AND NOISE| Hum and buzz are chronic problems with electronic instrument hookups. To track down the source, reduce guitar volume to zero. If the hum clears up,

it is coming from the guitar. Guitar hum is frequently affected by where you position yourself, and often increases when not touching the strings.

If the hum remains, unplug the guitar cable from the InterBlock. If this fixes the hum, try another cable.

If hum remains after unplugging the input, unplug any devices connected to the Effects Loop. If this fixes the hum, the problem is in the pedal board.

Gently wiggle all cables, listening for any fluctuation in hum level. Solderless cables often go bad after a year or two. If cables are good, confirm that the pedalboard power supply is not overloaded, which can also cause hum.

If the hum remains with nothing plugged into the input or effects loop,

the problem may be a ground loop between the InterBlock and outboard console. If possible, operate from the same AC strip, and if necessary, insert a ground-lift Direct Box between the Line Out and console Line In.

L OU D SCREECHING NOISES| Be sure the speaker output is only connected to a stand-alone speaker (or left unplugged). Accidentally connecting the speaker to a signal input will often cause runaway feedback or damage the SUPERBLOCK speaker output.
HE ADPHONE| The headphone jack is 1/4-inch to mate with professional studio-type head- phones. The sound should be centered. If sound only comes from one side, check with another headphone and confirm that the plug is fully inserted.

If using an adaptor to connect to mini-plug earbuds, confirm that it is good.

OVERALL SIGNAL FLOW:
The signal flow matches the layout of typical pedals, flowing from right to left. Jacks are located on the rear and left side, making it ideal to locate the SUPERBLOCK at the upper left corner of your pedalboard. The INPUT feeds the VOICE switch, passes through GAIN, LIMITER, 3-band EQ SECTION, out to the EFFECTS LOOP, returns to REVERB, then MASTER. The signal splits to the SPKR on the left side, and the CAB SIM switch which feeds HEADPHONE and XLR LINE OUT jacks. overflow
