THANK YOU Thank you for purchasing your Ashdown Engineering Amplifier and welcome to the family! We really think you’ve made the right choice and know that this amplifier will give you years of great tone and service. It is a machine though and needs to be looked after, please read... - Page 3 ASHDOWN ENGINEERING - 12-BAND 600 USER GUIDE INTRODUCTION After being asked by countless friends and Ashdown fans to re-introduce the formidable 12-BAND head, previously the MK-500. We proudly present the 12-BAND 600. The 12-Band bass amplifier uses a sought-after Ashdown pre-amp featuring a 12-band graphic equaliser for the most versatile tone shaping available and Harmonic Emphasis to provide the ultimate in Hi-Fi for Bass.

ASHDOWN ENGINEERING - 12-BAND 600 USER GUIDE FRONT PANEL FACILITIES INSTRUMENT INPUT - There are two Instrument Inputs. The first of these is a Jack socket suitable for all Passive or Active bass instruments with a conventional jack output. This will perfectly match the high impedance output from a passive bass but also has sufficient headroom to accept the lower impedance and higher signal level from active instruments. - Page 5 ASHDOWN ENGINEERING - 12-BAND 600 USER GUIDE This has a LEVEL control and can be switched in or out with the front panel switch. Used in moderation, you will find it adds a lot of bright, high harmonics to the sound giving definition and clarity not achievable in any other way.

Page 6: Useful Observations
ASHDOWN ENGINEERING - 12-BAND 600 USER GUIDE frequencies as low as 30 and 40Hz with any degree of efficiency. N.B. Boosting at 30Hz for instance will not add to the perceived amount of bottom end in the sound, it will only make your speakers flap to no useful effect. In fact boosting at 100Hz or 180Hz will have the apparent effect of adding far more bottom end than boosting at 30, 40 or even 60Hz. - Page 7 ASHDOWN ENGINEERING - 12-BAND 600 USER GUIDE Above this frequency range you will find it is better not to boost the signal as this will mainly emphasise any hiss present. This hiss will not be masked by the bass signal when playing due to the very small amount of bass guitar frequency content at 10 to 15kHz.
- Page 8 ASHDOWN ENGINEERING - 12-BAND 600 USER GUIDE MUTE/TUNE - The front panel MUTE switch provides a mute facility that can be used to silence all outputs from the amplifier except that from the TUNER output socket. This enables silent tuning to be carried out whilst the amplifier speaker outputs, the DI the Effects Send and the Line Output are all muted.

ASHDOWN ENGINEERING - 12-BAND 600 USER GUIDE REAR PANEL FACILITIES EFFECTS SEND/RETURN - A serial effects loop is provided at a level of 0dB. The EFFECTS SEND socket can also be used as a Line Out socket if required as the signal path through the preamp is only broken when a jack plug is inserted into the EFFECTS RETURN socket. -
