The 1970 shares similar parameters to those found on the Drawmer 1960, and anyone familiar with that or the 1969 will

be immediately at home, the difference being that the 1970 has an expanded feature set and therefore more controls,

such as variable mic impedance, "Big" and "Air". With the exception of the Instrument D.I. section, both channels of the

1970 are identical and may be used independently or linked for stereo operation.

INSTRUMENT

Instrument Input

A 1/4" jack provides a specialised instrument input stage with the addition of both gain and equalisation, suitable

for use with both active and passive guitar pickup systems as well as with electronic keyboards.

Gain

A variable control that provides up to 25dB of gain when the Boost Switch is off or 45dB with Boost.

Boost Switch

When on adds an additional 20dB of gain to the instrument

Bass EQ

Passive equaliser control which provides cut and boost at approximately 50-100Hz, the EQ being approximately

flat at position 5.

Treble EQ

Passive equaliser control which provides cut and boost at approximately 5kHz, the EQ being approximately flat

at position 5.

Note that, as the Bass and Treble EQ are passive they interact with each other altering the amount of cut and

boost and also the centre point of the EQ's as one control effects on the other.

E.Q Switch

Switches the two equaliser controls out of circuit when a flat response is required (off), or for an 'A/B' comparison

of EQ effectiveness.

Bright

When on adds 12dB of gain at approximately 2kHz-8kHz with a roll off at either side to simulate the

voicing of a typical guitar amplifier.

MIC

Gain

A twelve position microphone preamplifier switch adds gain in 6dB steps from 0dB to +66dB, making it incredibly

easy to replicate previous settings and have total control over levels.

SOURCE

Select

The source select is a six position rotary switch that, as well as setting the input source, also sets the load

impedance of the microphone.

In the +48V Phantom Power switch position the red LED will illuminate to indicate that 48V of dc voltage is being

sent down the XLR cable in order to power the electronics of a condenser microphone.

NOTE: DO NOT ACTIVATE THE +48V SETTING UNLESS THE MICROPHONE REQUIRES IT.

The switch can also provide three settings of load impedance in order to aid the matching for a dynamic microphone,

at settings of 200, 600 and 2.4k Ohms.

In addition the same switch sets the source to Instrument (via the front panel instrument DI section) and Line (via

the dedicated input on the rear panel).
