Introduction
Dear Music Lover,
The CIA-1T. is an integrated amplifier developed after many many years of study and research. Our
précis was simple; Create an integrated amplifier that within it’s power rating, establishes itself by
having a unique relationship to music and sound reproduction among today’s components...And while
maintaining said sonic excellence that we might through diligent effort, engineering expertise, and
perhaps a small measure of technical finesse, make operation simple and lifelong enjoyment plausible.
As such, we have implemented a case that is precision machined fromsolid aircraft grade aluminium.
Careful laser cutting and assembly lead to a beautifully finished component that’s beauty is more than
skin deep. Each design cue of the CIA-1T has not only form but function, and contributes to the purity of
sound, and life-like quality one can obtain from Crayon. The case, rugged yet elegant, serves to
stabilize the internal electronics while acting as a very effective heat sink to keep unwanted
temperatures away from any signal carrying circuit.
All internal tracing and signal runs are kept as minute as possible as to not corrupt the music in any
fashion. Using the newest technologies, in this case, a PCB design called Broadband Dirks’
Decoupling (named for Professor Dirks) decouples the power supply up to t GHz to provide extreme
electrical stability, and the lowest possibility of any electromagnetic interference.
Further care is taken by using cross regulators to stabilize the power supply of the preamplifier in the
often disturbed region of 1Hz to 10MHz, thereby applying balanced current regardless of operating
conditions.
The Crayon CIA-1’s output stage contains current feedback, (not signal feedback), which is a new
method used in output stages that we feel makes the CIA-1T all the more celebratory.
Despite common parlance, A Swiss made Switching Power Supply, and German designed controls
round out what is currently our finest effort in the vast world of integrated amplifiers. We have
developed this product without compromise, and feel certain that our efforts will lead you to experience
your music with a viscerally present and lifelike portrayal that will be newin your experience. Your CIA-
1should be with you for years. Please, should you have a minute, let us know how you like it.
Sincerely,
Roland Krammer
Principle/Chief Engineer

Power On/Off
When you turn on the power switch on the back side, light up the [MC-LED] 3 times a second on and
then the amplifier is in standby mode.
Press the Standby button on the unit or remote control. Subsequently, all 4-channel LED light up several
times. Then the device is in active mode. The selected channel is displayed by the corresponding LED.
The MC-LED only lights up when you had programmed the moving coil mode.
Press again the standby button on the unit or the remote control so you switch the unit back to standby
mode.
The standby sequence is shown in which the channel LED 1-4 sequentially light up. Then the [MC-
LED] lights 8 times on. After that the unit is in standby mode.

Basic Information
MM/MC Setting
To activate the MC mode of phono preamplifier, press the Channel Select button and hold it down.
Now press short the Standby button and after then release the channel select button again.
The MC-LED will now light up.
To disable the MC mode again is the same procedure to execute.
!!! Important !!! This procedure only has an effect if a phono preamplifier (Optional) was installed.
Each setting is stored in the EEPROM and retained even when the unit was turned off.

All the other keys have no function.
With the key [F] the function of the remote control can be switched from "amplifier" to “CD / SACD
Player”. After pressing this key, the selected mode will be indicated by flashing of the LED. 2 times
long flashes = Amplifier, 4 short flashes indicate the CD / SACD Player mode. The setting "Amplifier"
refers to the device "CIA-1T".
Insertion and change of batteries
At the back of your remote control there is the battery compartment fitted with a screw. Remove this screw with a suitable
screwdriver (PH1). Thereafter you can pull out the battery compartment of the remote control.
Please Note:
Insert the batteries according to the marks on the inside of the battery compartment. Remove immediately possiblyrunning
out batteries. Dispose the old batteries according to the instructions of the respective manufacturer.
After insertion of the batteries push the battery compartment again into the remote control and screw this together.
The remote control is powered by two 1.5 volt alkaline batteries (IEC LR 03, AAA). We recommend you to use only new
batteries. In any case you should never use old and new batteries together because the efficiencyof your remote control can
be strongly affected and in addition, shorten the life span of the batteries substantially. After you have inserted the batteries
please press a key and examine whether the red light-emitting diode lights up; this is the confirmation that the batteries were
properlyinserted.

13
Operation
Channel selection by pressing the key.
The channel selection to a channel is further switched by pressing the channel select button. After a short
delay, the next audio channel is switched. If the channel 4 is turned on, the channel 1 will be activated
by re-pressing the channel select button again. (1-2-3-4-1-2-3-4, etc.)

14
Operation
Channel selection by remote control
The remote control has 2 channel selection functions, channel selection [+] and channel selection [-]
This allows you to select the channels in both directions. The procedure is otherwise the same as with
the Channel Select Button on the device.
If you turn on the CIA-1T in the standby mode, the last selected channel selection in the EEPROM is
stored. After restarting the device starts with the last channel setting.

15
Operation
Mute
Press the Mute button on the remote, the set audio channel is switched off and indicated by a blinking
channel selection LED.
Again to press the mute button will disable mute mode and switch on the audio channel again.
The mute mode is canceled by any other function too, such as channel selection or volume change using
the remote control, or also by pressing the channel selector button on the device.
Power Amplifier Mode
Rear wall CIA-1T
With the switch between unregulated RCA output and the speaker output sockets you can switch the
CIA-1T into the pure Power Amplifier mode. Input 2 is switched active. The volume control is
bypassed. (Caution !!!! Do not switch to PA mode if a source without volume control is connected
to input 2 or the volume is completely turned on. Your speakers will thank you !!!)
The LEDs on the front panel indicate the active input inversely. Dark LED = active input. Luminous
LEDs show inactive inputs. Thus, one can immediately see whether PA mode or normal mode is turned
on.
Switch up = PA active (power amplifier)
Switch down = IA active (integrated amplifier)
(Switch middle = IA active)

When using a moving magnet pickup, switch 4 of both channels must be switched ON in any case. Thus
set the inputs to 47KOhm and 47pF (Load Resistance Load Capacity). The capacity must be set as
specified by the manufacturer pickup (Load Capacity). Intermediate values can be achieved by parallel
connection of the capacity.
Example: required load capacity = 200pF switch 4, 3 and 2 to ON (50pF + 50pF + 100pF)
All other switches must be set to OFF.
When using a Moving Coil cartridge switch 1to 4 of both channels must be turned off (OFF).
Switch 5 to 8 are now to set, by specification of the pickup manufacturer.
Some MC pickups require a terminating resistor of 1 Kohms. The switch 8 must be switched ON.
500ohm or 100ohm and are also commonly used value.
Here, too, the intermediate values can be achieved by parallel connection.
For example, switches 7 and 8 to ON gives a resistance value of 333 ohm = 1 / (1 / T7 + 1/ R7).
Do not forget to connect the ground wire of the Turntables via the M3 screw to ground the unit.
