Frequently Asked Questions - Rootmaster EVOII Ashdown Engineering

How to adjust the input level on the Rootmaster EVOII?

Use the Input control so that the VU meter shows 0 VU at average playing, with occasional peaks in the red. Adjust after changing EQ if necessary.

What is the difference between passive and active inputs?

The passive input has high sensitivity (3.9 M ohms) for basses without built-in preamp. The active input has lower sensitivity (10 k ohms) for basses with active preamp (battery).

How to use the compression on this amp?

Enable compression with the push button, then adjust the compression level. A small amount adds fatness and sustain, a large amount reduces dynamics. The output level is automatically compensated.

How to connect an FS-2 footswitch?

Connect the footswitch (sold separately) to the FS-2 jack on the rear. It allows remote activation/deactivation of sub-harmonics and overdrive.

Can I use the amp with headphones for practice?

Yes, connect headphones (minimum 32 ohms) to the headphone output (3.5 mm jack) on the rear. The speaker is then automatically muted.

How to connect the amp to a mixing console?

Use the DI XLR output on the rear. Connect it to a microphone input on the mixer. The signal is post-EQ and post-effects, with a nominal level of -20 dBu.

What minimum impedance for speakers?

The minimum load impedance is 4 ohms. Use fully isolated Speakon cables. Both outputs are active, do not let them contact the chassis.

How to use the effects loop?

Connect Send to the input of your effect, and Return from the output of the effect. The signal is broken only when a plug is inserted into the Return.

What does the Shape button do?

The Shape button overlays a fixed EQ curve that boosts lows (+8 dB at 50 Hz) and highs (+10 dB at 10 kHz) for a punchier sound.

How to maintain my Rootmaster EVOII amp?

Unplug the device before cleaning. Use a dry, soft cloth. Avoid moisture and chemicals. For repairs, contact an authorized center. The fuse is located under the mains connector.

USER GUIDE

Inputs

There are two choices of instrument input, these are marked passive and active. The passive input is high sensitivity and high impedance to suit passive bass instruments. The active input is much lower sensitivity and impedance to accurately match the signal from active bass instruments i.e. Those with a built in battery powered pre-amp.

Input control

The input control sets the signal level through the preamp in conjunction with the input level vu meter. This is adjusted to give a reading of 0vu on the meter for average playing dynamics with occasional peaks into the red region. Please note that the setting of this may have to be re-adjusted after modification of the E.Q. controls.

Shape

With this button in a fixed E.Q. is superimposed on the pre-amp to give a bass & high boost to the sound. This gives +8db at 50hz and gives +10db at 10khz.

E.O.

This button switches the equalisation section in or out i.e. the Bass, Middle and Treble controls and the two rotary controls placed between these.

ROOTMASTER EVO II

USER GUIDE

Equalisation

This consists of bass, middle and treble controls with two more rotary controls placed in-between. This can be used in a number of ways: Firstly as a very simple bass, middle and treble tone control section as found on older traditional amplifiers. This is done by leaving the 340hz and 1.6Khz controls set in their centre positions and using only the bass, middle and treble controls to alter the overall tone.

Secondly, if more control is required then the 340hz and 1.6Khz controls can also be used to tailor the E.O. In the regions between the main tone controls. This provides a very versatile equalisation section, it is simple to understand and operate, yet provides a wide degree of variation. It retains the simplicity of a three control tone section but provides the flexibility of a graphic equaliser.

Compression

Adding a small amount of compression gives a fat bottom end to the sound and allows a greater volume of amplification to be used without the playing peaks distorting the amplifiers output stage.

You will also find that this will add definition to your playing bringing out notes within a run more clearly as it evens out the dynamics of your playing. A large amount of compression can be used as an effect but it will tend to reduce the dynamics in your playing to such an extent that the volume of the note will be the same no matter how hard or soft you hit the string. Compression also adds sustain to notes making them longer before they die away.

ROOTMASTER EVO II

USER GUIDE

The compression level control adjusts the degree of compression applied to the bass signal. For this to function correctly the input level must be correctly set as described in the input control section above. When the input level is correctly set there will be hardly any difference in volume between compression in and compression out. This is because the RM automatically compensates for the reduction in level that would be apparent when compression is added by increasing the overall gain to restore the volume to its pre compression level, because of this you may notice an increase in background noise with high compression settings. Compression is switched in/out with the push button adjacent to the compression level control.

Overdrive

This is a valve/tube emulated overdrive that is variable from a slight 'edge' or 'warmth' through to a fairly aggressive overdrive/distortion effect. The actual degree of overdrive applied to the bass signal is also dependent on the setting of the input level control. The higher this is set, the greater level of overdrive can be applied using the overdrives own rotary control.

Overdrive can be switched in with the push button above and to the right of the overdrive rotary control. The amount of drive applied to the overdrive circuit is adjusted using this rotary control. The over-driven bass signal is applied in parallel with the dry bass signal to ensure you never lose the full bottom end from your bass. Overdrive is situated after the compression allowing for a sustained over-driven bass signal to be produced by adding a degree of compression along with the overdrive itself.

ROOTMASTER EVO II

USER GUIDE

Sub harmonics

This section produces sub harmonics an octave below the notes being played. The level of these sub harmonics relative to the straight bass sound can be adjusted using the level control. This is very effective in thickening the sound and you will find in use that only a small degree of this lower octave is required to really fill out the sound and provide a character that is not possible by any other means. The degree of sub harmonics is also dependant on the setting of the bass control.

Sub harmonics are switched in/out with the push button below and to the left of the sub harmonics level control.

Output level

The output control adjusts the overall level of the amplifier. Adjust this for your preferred overall stage playing volume.

Line Mix

The line mix is an output control adjusts the overall level of the amplifier vs the Line input signal. Adjust this for your preferred overall mix if using a line input such as a backing track.

D.I.

A balanced D.I. Is provided on the rear panel xlr socket. This provides a post E.Q. Post effects signal.

The output signal from this xlr socket is set to a level and impedance suitable for connecting directly into a balanced microphone input of a mixing desk for either direct injection into the pa system or for recording.

ROOTMASTER EVO II

USER GUIDE

Effects send/return

A serial effects loop is provided at a level of 0db. The effects send and return sockets for this are on the rear panel above the d.l. Socket.

The effects send socket can also be used as a line out socket if required. The signal path through the preamp is only broken when a jack plug is inserted into the effects return socket. The effects send is situated after the E.O.

Line In

This input socket provides a line level signal that can be used in conjunction with the Line in Level control on the front panel for connecting a line level instrument of playback device.

FS-2 Output

The FS-2 Output is for use with a double latching foot-switch, this controls the Sub Harmonics and also the Drive for ease of access (foot-switch sold separately).

Headphone Output

There is a 32 ohm headphone output on the rear panel for use in silent practice.

Speaker Outputs

There are two speakon out sockets located on the rear of the amp for use with appropriate cabinets. Min load of 4 ohms. All speaker connections used must be of the speakon type and fully insulated. These amplifiers
