Meterbridge and Clock
Overview
The console’s meterbridge houses three pairs of left-right VU meters
(Program, Audition and Switched; see “Meter Output Module” Chapter 7),
the digital timer display, left and right cue speakers (controlled by the CRD-
500 Control Room Module; see page 5-2), and the console clock.
The meterbridge assembly hinges open for easy access (VU meter lamp
replacement, setting the clock). Simply remove the three black #4 flathead
screws along the bottom lip of the meterbridge, just above the tops of the
console modules and swing the bridge up and back until it rests in a fully
opened position.
Digital Timer
The console timer control buttons are located on the MOD-500 Meter
Output Module (see page 7-2).
The timer is provided with an AUTO-RESTART function so programmed
input modules can automatically reset the timer display to zero and start a new
count, allowing the announcer to easily track his own pace.
The START/STOP button halts the timer, holds the last count, and then
restarts and accumulates the count when depressed again
—
perfect for compil-
ing tapes of desired duration.
RESET has a dual-mode capability:
- if you depress it while the timer is counting, the display will instantly reset
to zero and start a fresh count;
- if the timer is already stopped, depressing this button will reset the timer
to zero, where it will hold until start is pressed.
HOLD button allows you to hold the display for a longer viewing duration,
while still allowing the counter to continue in the background. Releasing the
button will then display the current count.
Console Clock
The Wheatstone digital clock is a six-digit time-of-day clock with LED
display. The clock is designed with CMOS circuits and an on-board crystal-
controlled time base oscillator. There are two basic parts to the clock: a main
PCB containing the clock circuits and clock set controls (also may include
capacitor backup) and a second PCB containing displays. Clock set controls
may be accessed by removing the meterbridge cover.
