THE VU METER
The VU meter provided on the front panel gives you a visual display of the
output of the amp as its being played. This can be used to ensure clean
headroom or to dial in
something a little more aggressive….
-
INSTRUMENT INPUT
There are two instrument inputs, UK has a more compressed and tight classic British tone. The US input has great headroom producing a cleaner tone. -
EFFECTS SEND/RETURN
A tube driven and recovered effects loop is provided, this is situated between the preamplifier and power amplifier, ahead of the master volume. The signal level is suitable for driving a wide range of effects pedals, the level present being entirely dependent on the level of pre-gain being used. Only effects should be used in this loop. -
BOOST
An overdrive boost that can be turned on and off with the FS-1 Footswitch (sold seperately), default setting is ON so you can turn up the overdrive volume without using
a footswitch and dial in some growling overdriven tones. -
GAIN
Use the gain setting to determine how clean or dirty your sound is regardless of the master volume setting. -
5. 4 BAND EQ
This consists of Treble, Middle and Bass controls with a Presence, which operates as a high-frequency shelving boost. -
VOLUME
The volume control adjusts the overall level of the amplifier. Adjust this for your preferred overall stage playing volume. -
CLIP
This is to indicate when clipping occurs on the output signal of the Two notes DynIR output to maintain a clear representation of the DynIR. -
OUTPUT LEVEL
This is to set the output volume of the Two notes DynIR output DI on the rear of the amp. -
PRE-SET
Select from 6 available on board official Ashdown Two notes DynIR impulse response cabinets designed by us for you. See table *T.1 for list. -
MAINS INPUT
The amplifier is fitted with a standard IEC connector and supplied IEC lead correct for the country in which you reside. The Pre-set input VOLTAGE is shown on the rear panel together with fuse ratings.
-
MAINS
Power on and off with the switch provided once connected to the mains input. -
TORPEDO OUT
This is a balanced XLR DI output derived from the DynIR output. -
HEADPHONES
There is a 32 Ohm headphone out for use in silent practice. -
FS-1 FOOTSWITCH INPUT
Input to connect an FS-1 footswitch (sold seperately), use to turn boost on & off. -
15/16. SPEAKER OUTPUTS
Two speaker output sockets are provided at an impedance of 8 or 16 ohms only ONE must be used at any one time, the socket being chosen to match the impedance of the cabinet combination in use at the time.
The on-board reactive load enables the amplifier to function without a load connected. -
TORPEDO LINE IN & DI LINK
The TORPEDO LINE IN & DI LINK is an option that enables you the possibility of using the MF 484 2.N as a re-amping unit to run your pre recorded lines giving them some alternative tonal options with a number of alternative settings available via the embedded Two notes Torpedo.
The DI LINK push button links/unlinks the DIRECT DI and DynIR to isolate the signal. -
DIRECT DI
This is transformer derived from the output and as such will have all the adjustments made with the tone controls, all effects in use and some influence from the speaker
in use. The level obtained is dependent on playing volume. But as a general rule is suitable for line level (0,775V). -
GROUND LIFT
A ground lift is fitted. -
MIDI IN/OUT
Midi IN and OUT sockets are provided to enable control via a midi controller (available seperatly) over the available functions via the Two notes Torpedo. (See MIDI for more info). -
USB – PROGRAM/CHARGE
To either program the on-board Two notes Torpedo embedded firmware or with the handy option to keep your USB device charged… -
TORPEDO BOOT
The Boot push button is a failsafe feature for in-field servicing. It ensures there is always a way to restart and reprogram a frozen unit. In particular, if an in-field update
goes wrong, it allows the end user to restart the unit at home, without having to send the unit to a service center, which can save lots of time and money.
THE AMPLIFIER
POWER AMPLIFIER
All Valve design featuring a fully floating paraphrase inverter, 4 x EL84
power tubes with individual self biasing, and Zero negative feedback for a
self limiting open loop response and a good sensitivity to the speakers in
use. Output power 30 watts continuous average into 16 or 8 ohms.
VALVE COMPLEMENT:
PRE – 3 x ECC83 POWER – 4 X EL84
MIDI
The MF 484 2.N handles both pre-set change commands (Program Change or PC) and
parameter change commands (Control Change or CC). This way, you can interact
with all the parameters on the unit from any kind of standard MIDI controller,
like a MIDI pedalboard or a keyboard.
Select if the unit is to receive to Program Change and/or Control Change
commands. For example, if you plan to use the pre-set switching (PC), the CC
receive can be Off.
Set a MIDI channel for the unit to receive. You can choose to receive all
channels, which is useful when you don’t know exactly on which channel the
commands are sent. With the MIDI monitor, check the correct reception of the
commands by the Two notes Torpedo.
See section MIDI Mapping for the tables concerning Program Change and Command
Change.
PROGRAM CHANGE (PC)
Each pre-set on the MF 484 2.N has a single program number. The pre-set 001 of
the machine is triggered by a MIDI PC 1, you can address the 128 pre-sets,
with MIDI PC 1 to MIDI PC 128. This way, it is possible to randomly access the
pre-set by sending the appropriate MIDI PC number.
CONTROL CHANGE (CC)
The table on page 16-18 indicates the Control Change numbers for every
parameter, as well as their range and behaviour.
THE TORPEDO TECHNOLOGY
To bring you realism and playing comfort, Two notes has developed a unique
technology based on an adaptation of convolution techniques. Starting with the
measurement of an actual cabinet and microphone setup, the embedded Two notes
Torpedo can accurately reproduce the system as it was measured, as well as the
microphone’s position in space.
To take full advantage of these digital algorithms, the highest quality audio
design assures a perfect analogue-to-digital conversion and a huge dynamic
range to retain the ultimate playing experience.
This product has been thoroughly tested in professional studios and stage
environments and is the alternative many musicians are looking for, to achieve
a professional sound capture of their amplified instruments. The embedded Two
notes Torpedo will give you the elusive sound of the greatest recording
studios and producers, anytime, anywhere.
3RD PARTY IMPULSE RESPONSES
The MF 484 2.N is capable of delivering the best guitar tones by using the
Torpedo technology, but you can also embed impulse responses that you have
purchased or downloaded for free from 3rd-party developers, in .WAV or .AIFF
formats. You can upload third-party IRs in the MF 484 2.N using the free
Torpedo Remote software.
