Page 7: Introduction
This Trace Elliot range is the latest evolution of a line of products that were always known for their sophisticated features, high quality construction, use of state of the art technology and reliability. Many of the original ideas have become industry standards and are included within this range, however, around these are even more features to inspire musicians to create the music that they want to hear. -
Page 8: Basic Comparison Of Features
(1) Once you unpack your Trace Elliot, plug the power cord into the socket on the rear panel and connect to a mains socket supplying the proper AC line voltage for your unit. This is located on the rear of the unit, near the mains inlet and power switch. - Page 9 (8) Now gradually turn up the OUTPUT LEVEL control. Do this slowly to avoid any sudden level changes that could damage your hearing; these are loud amps! Set this at the desired playing volume. (9) You will notice that the unit will have defaulted to a setting of everything off except the PRE SHAPE circuit.

(12 Band) is shown, this section applies to all 12 Band products and not to any 7 Band products. Where a specifi c model is shown in brackets, e.g. (AH1200-12), then this applies only to that product. The feature being explained is shown in upper case, the type of control is shown in lower case. If there are any terms you do not fully understand then please refer to the glossary at the back of this manual. -
Page 11: Input Socket
(1) INPUT socket This is to connect the 1/4” jack lead from your instrument. Alternatively, if any effect units are being used before the amplifier then the output from the last unit is connected here. When the INPUT is not in use the amplifier is automatically muted to prevent any unwanted noise. -
Page 12: Tuner Socket (7 Band)
The signal from this socket is present all at times regardless of any other settings including MUTE. (6) PRE SHAPE switch This activates the circuit for the classic Trace Elliot ‘Mid Pre-Shape’ that all users of previous Trace Elliot graphic style amplifiers will recognise immediately. As it is our ‘signature sound’, these amplifiers are designed to default to this setting when initially turned on. -

7 Band and 12 Band. Both types are very powerful tools for controlling the tone of your instrument. The design of a Trace Elliot graphic equalizer is very different from a standard sound reinforcement EQ. 15dB of cut or boost is available for each band, but instead of being spread mathematically... -
Page 14: Compressor Switch And Rotary Control (7 Band)
These design differences are in common with traditional Trace Elliot amplifiers and are part of the sound. With the controls all set at 0dB (their mid ‘click’ position), no change is made to the signal. Moving a slider up will progressively increase, or ‘boost’, the frequencies centred around the frequency marked above the slider. -
Page 15: Compressor Switch (12 Band)
The compressor in the 7 Band series uses studio quality, dedicated dynamics controller integrated circuits and has been specifically designed for bass guitar due to the common problems often experienced when using a normal, single band compressor in this application. With a standard compressor, the transition from non-compressed to compressed, i.e. -
Page 16: High Band Rotary Control (12 Band)
(16) HIGH BAND rotary control (12 Band) This adjusts the amount of compression applied to the high frequencies in the signal; the further clockwise the control is set, the more the dynamic range of the high end will be squeezed. The compressor section of the 12 Band series uses two separate studio quality, dedicated dynamics controller integrated circuits, and has been specifically designed for bass guitar due to the common problems often experienced when using a normal, single band, compressor in this application. -
Page 17: Send Socket (7 Band)
Compression applied to the high band will directly effect the attack portion of the note and should be used carefully. However, even extreme settings can produce some interesting effects for both slapping and fretless techniques and will help to make harmonics jump out in the mix. If the VALVE drive circuit is being used at high settings then the high band compressor can be used to control and smooth out the overdrive produced resulting in quite a processed, produced sound. -
Page 18: Multipurpose Red Led Above Output Level
The actual power level produced from the amplifier will be dependent on the input signal and the settings of the other controls. Once set for a performance it can be left alone and the MUTE function can be used to turn the signal off between songs or sets. -

REAR PANEL 7 BAND 12 BAND N.B. Within the 7 Band and 12 Band ranges the rear panels may vary slightly from those shown above. (24) EXTERNAL CONTROL 8 pin DIN socket(s) – BFC-4 (7Band), BFC-6 (12 Band) The socket(s) are for connecting to the footcontroller supplied with the unit. It should be connected before the unit is switched on. -
Page 20: Di Earth Lift Switch
To re-synchronize the switching simply turn the unit off for 5 seconds and then back on. Both the amplifier and footcontroller will power up in the normal default state of PRE-SHAPE on, all other functions off. The 12 Band units have been designed with two EXTERNAL CONTROL sockets. These make it possible to use two footcontrollers, either of which can control the amplifier. -
Page 21: Loop Level Rotary Control (12 Band)
(29) LOOP LEVEL rotary control (12 Band) This sets the overall level of the signal while the LOOP is on. Therefore, if the LOOP is not selected this has no effect, but when the LOOP is selected this is a very important control for balancing the levels. The control has been calibrated so that if a simple loop is set up, SERIES, FULL RANGE, MONO, then with the control at the 12 o’clock setting there will be unity gain when switching the LOOP on and off. -
Page 22: Tuner Socket (12 Band)
The 12 Band preamp is stereo from the EFFECTS LOOPS through to the LINE OUTS. Units with two output stages (e.g. AH1200-12) remain stereo through to the speaker outputs. Units with one output stage (e.g. 1215, 1210) have the two channels mixed into mono at the final preamp stage. Therefore although the signal from the speaker output will be mono, the DI and LINE OUTs retain stereo separation for recording or sound reinforcement purposes. -
Page 23: Outputs-Left & Right Sockets (12 Band)
Trace Elliot amplifi ers are designed to deliver their rated RMS output power into 4 ohm speaker loads. Therefore each amplifi er can drive 1x 4 ohm cabinet or 2x 8 ohm cabinets (in parallel). -
Page 24: Front Panel Brightness Rotary Control
The back lighting is produced by state of the art, high powered LEDs positioned behind the Perspex (plexi- glass) part of the front panel and gives the familiar green glow of Trace Elliot amplifi ers on stage. LEDs have been used as they do not produce any electronic noise or hum that could be detrimental to the sound. -
Page 25: Additional Information
ADDITIONAL INFORMATION POWER AMPLIFIERS The power amplifier sections within these Trace Elliot products are high efficiency advanced designs. They are designed to withstand rigorous use and include protection for over-temperature, over-current and short- circuits. Although designed to run comparatively cool, the high power versions do contain fans. These blow cool air from the outside across critical components and back out through the vents. -
