CAUTIONS
AC MAINS SUPPLY
Your blak Integrated Amplifier is set to operate from a fixed supply voltage which is marked
on a label next to the mains input plug. Before connecting the mains lead please check that
your mains supply corresponds to the label as below:
230V Products: Voltage Range 220V – 240V
115V Products: Voltage Range: 110V – 120V
100V Products: Voltage Range: 90V – 110V
The mains lead supplied with this product has an IEC mains socket which plugs into the IEC
connector on the unit’s rear panel. The other end is normally attached to the appropriate
mains plug for your country. In the UK this is the standard UK13A plug.
This plug should ordinarily not be removed from the lead. If you do remove it, please dispose
of it safely so that it cannot be plugged into a mains socket whilst in a potentially dangerous
condition. We suggest that you obtain from your dealer a complete set of replacement leads.
Should you move to another area where either the mains voltage or the mains plug are
different from those as supplied with your Integrated Amplifier, please contact the appointed
Roksan distributor for assistance.
Please observe correct mains polarity at all times.
The Integrated Amplifier mains fuse is located on the rear panel next to the IEC mains connector. This must only be replaced by the fuse of the type and rating as described on the fuse
rating label on the rear panel of the unit.
This product requires connection to earth (ground). The earth wire (in the UK this is colour
coded green/yellow) of the mains cable supplied with your Integrated Amplifier must be
connected to a suitable earthing point established for this purpose by your electricity supply
company. If you are in any doubt, consult a qualified electrician.
If the equipment is likely to be unattended for some time, unplug it from the mains supply.

SETUP
CONNECTING MAINS POWER
Please refer to the front & rear panel views.
The moulded IE connector or the supplied mains lead should be plugged into socket (21) on
the rear of the unit first and then plugged into the mains supply. The mains power switch (1) is
on the front under side of the amplifier. This switch can be left on; if however the amplifier is
likely to be unattended for a long period of time, switch it off and unplug the mains lead from
the wall.
SIGNAL CONNECTIONS
There are 6 inputs on your blak Integrated Amplifier. Three are line level and will accept
virtually all currently available source components, the other three are a phono input, aptX
Bluetooth wireless input and in the USB Version only (which houses an internal high quality
DAC) a ‘type B’ USB input.
The Phono input is factory set for Moving Magnet cartridges to accommodate record players
fitted with MM phono cartridges.
All the inputs use gold plated RCA phono connectors and should be connected according to
the standard convention.
• Right Channel - Red
• Left Channel - Black or White
Also in accordance with standard practice, the upper row of phono sockets carries the left
channel and the lower row carries the right channel.
MC INPUT CONNECTION
If you wish to use a Moving Coil cartridge, an in-line MC step-up transformer should be
connected to the Phono Input. Alternatively a dedicated phono stage can be connected to a
line level input. For advice and demonstration of Roksan state of the art turntable
reproduction systems contact your authorised retailer.

LOUDSPEAKER CONNECTIONS
The right and left loudspeakers are connected to the amplifier via the rear panel binding
posts. Carefully observe polarity ensuring that the RED (+) speaker terminal is connected to
the RED (+) amplifier terminal and the BLACK (-) speaker terminal to the BLACK (-) amplifier
terminal. When both left and right channels are connected to the relevant speaker terminals
the amplifier is ready for use.
IMPORTANT NOTE:
For optimum performance it is recommended to use high quality inter-connect cable such as
Roksan HDC-03A High Definition Analogue Cable.
For optimum performance it is recommended to use high quality cable such as Roksan HDC
03S High Definition Loudspeaker Cable. Many speaker cables such as the Roksan HDC-03S
are directional. Please observe this characteristic. DO NOT use a speaker cable with
conductor size less than 16 AWG (1.6mm Diameter). The binding posts accept conductor
sizes up to 12 AWG.
HEADPHONE CONNECTION
To listen through headphones, connect a 6.35mm 1/4 inch Stereo Jack Plug to the
headphone socket (2).
OPERATION
SWITCHING ON
The mains power switch is located on the front left under side of the amplifier. This switch can
be left ON for normal operation. If unattended for a long period of time (going on a short
break, holidays etc.) the mains power should be switched OFF and the power cord
disconnected from the mains power input. When switched ON, your blak Integrated
Amplifier will go into standby mode, which is characterized by a single light illuminated on
the highest value volume LED. Pressing the OK button will take the amplifier out of standby (if
you wish to regress to standby mode, press the OK button twice in short succession).
OUTPUT SELECTION
For loudspeaker output, the headphone switch (4) should to be toggled to the left. For
headphones ouput, the switch should be toggled to the right.

VOLUME CONTROL
The volume control on the blak is a precision device. It follows algorithmic law so that its
response approximates that of the human ear. The series of LEDs around the volume control
indicates the volume level. When the volume control is at 0, the output is automatically
muted. Turning the volume knob will take the unit out of mute mode.
The volume can also be muted by pressing the MUTE button on the R7 remote control. When
unmuted, the volume will return to it’s previous level.
FRONT PANEL CONTROL
The INPUT Selector Buttons (4) and (5) shift through a list of the inputs one click at a time.
Pressing OK will confirm the selection, otherwise the unit will revert to the current selection.
The blak Integrated Amplifier has an input selection memory. When switched on, it will
automatically recognise the previous input selection. The selected input will show in the LED
display window.
Pressing the OK button twice in quick succession will take the unit into standby. Pressing it
once will bring the unit out of standby.
BLUETOOTH CONNECTION AND PAIRING
Make sure your device’s Bluetooth is enabled and select the Bluetooth input on the
amplifier. This will select the Bluetooth source and the characters ‘BT’ will flash continuously
on the display. When your device has found the amplifier, ‘Roksan blak’ will appear on your
device. Next, connect to pair your device. When paired or connected ‘BT’ will stop
flashing and remain on. You are now ready to stream music to the blak from the paired
device. If your device is aptX compatible and contains high resolution audio files, then these
will be streamed in the original high quality bit rate through the blak amplifier.
Whilst streaming Bluetooth data, if you wish to revert to another input, simply use the input
selectors to the desired choice and press OK as normal. You will then have to re-connect the
device but pairing is not necessary.
USING THE INTERNAL DAC AND CONNECTING TO THE USB PORT
(USB VERSION ONLY)
The USB input can be used with a Windows or Mac operating system computer using a USB
B-type connector cable. Select the USB input using the input selection buttons and press ‘OK’.
NOTE: It’s always recommended to use a directly connected USB socket. For example, front
panel USB connections on desktop pcs often have a substandard internal wiring that can
cause degradation to the USB signal.
