2.0 Master Module

The Dayner master module contains all the electronics for

the summing of the left/right signals, aux master

section, a single frequency oscillator, talkback section,

subgroup amps, 3 tape returns as well as the Control Room

Monitor section. The width of this module is 90mm (3 times

the width of a channel module).

2.1. a. +18v

b. -18v

c. +48v

These three LEDs indicate that power is present on the

voltage rails throughout the Dayner chassis. +/- 18 Volt

for the electronics and +48 Volt phantom powering for

condenser microphones and direct injection boxes.

2.2. a.b. Oscillator

The DAYNER has a single frequency, low distortion, phase

shift type oscillator which produces a lKhz sine wave tone.

The level can be adjusted via the (2.b) control.

Switch (2.a) routes the oscillator signal to all mix

busses in the DAYNER. To provide the channel output

with the sine-wave, it is necessary to activate one of

the from sub switches on the output section of each

module. Use the trim control for fine adjustment of

each channel. Because the meters on the Dayner Series

are all peak ballistics, they should read -10 on the

channel output meters when the (2.b) control is wide open.

If you measured the +4 output of the channel or master,

it would read 1.23 volts on an AC volt meter. The LED

meter is actually reading -6 on the scale, however, there is

no LEDs between -3 and -10. All other outputs, such as aux

outputs and master left/right outputs only receive the tone

if their associated master controls are opened.

Another function of the tone switch is to DIM the control

room monitor speakers by 20db.

2.3 talkback volume

The built in electret microphone can be adjusted in level

and is permanently routed to the Aux 1 and 2 busses

optional to Aux 3 thru 8). To avoid feedback the talkback

(switch 7 on drawing) also dims the C.R.M. output by 20dB.

2.4 aux masters 1 thru 8

These 8 controls are the aux master levels to the 8

aux outputs. Every output has an associated A.F.L.

(after fade listen) switch to solo and meter the signal.
