DRAWMER

CONTROL DESCRIPTION

Each of the four channels are (almost) identical, with the controls for each as follows:

Inputs

 1

  MIC/LINE

Switches the level of input  4  between Mic or Line, with LED indication. When in the 'Line' position
the phantom power switch is bypassed, the input has a 20dB pad, and the input impedance alters
to >10k Ohms.

 2

  PHANTOM POWER

A switch pr48V Phantom Power down the XLR cable to microphones that require it.
NOTE: DO NOT ACTIVATE THE +48V SWITCH UNLESS YOU ARE SURE THAT THE MICROPHONE
REQUIRES IT.

 3

  GAIN

A twelve position switch adds gain in 6dB steps from 0dB to +66dB,  to have total control over levels
and make it incredibly easy to replicate.

 4

  V.U. METER

Each channel has an six LED VU meter, covering the range from -20dB to +18dB.

 5

  LISTEN

Activating the switch will route the input from that particular channel to the headphone section for
monitoring. Each channel can be active seperately (solo) or all can be monitored at once if preferred.
(SEE HEADPHONES).

CHAPTER 2

The control layout of the Drawmer 4X4R comprises of the mains inlet, headphone monitoring section, and four identical pre-
amplifier and splitter channels - the only difference being the link switches. Each of the four channels is based around
Drawmer's own discrete component mic preamp, which delivers very low distortion and a wide dynamic range, providing upto
66dB of switchable gain, mic/line selection and phantom power, as well as four outputs, either electronic or transformer
isolated (factory fitted optional extra).

The location of components has been carefully considered in order to be very intuative and also to make cable routing as clean
and unobtrusive as possible. When fully loaded the 4X4 will have a total of twenty XLR cables, a headphone cable and also the
mains - with four of the XLR outputs conveniently located on the front panel for easier access.
