headphones, one on the front panel, the other on the rear panel. This
is convenient when two headphones are required at the same time, for
example presenter and guest in a broadcast application. The same
signal is available from both.
different styles, impedances and volume ratings. To get the best from
your system we recommend that you use high quality closed ear
headphones in the range 30 to 600 ohms. 8 Ohm headphones are not
recommended.
WARNING
Some headphones are more sensitive than
others and can produce higher output levels. To avoid damage
to your hearing start with the PHONES level control at minimum
and turn up only as much as is needed to maintain comfortable
listening level. Do not drive headphones at high listening levels
for long periods of time.
EXTERNAL INPUTS
addition to the mono and stereo channels. Each has a pair of TRS
jacks to accept a line level stereo source. For mono sources plug into
the L jack only leaving the R jack unplugged.
MIX1(2) ROUTING SWITCHES
switches determine how the external inputs are to be used. There are
two main applications:
Mix Inputs To connect additional stereo or mono sources to either or
both MIX1 and MIX2. For example, you could use these to return the
processed output from effects devices such as reverb, to accept an
input from a submixer, or for 2-track replay into the mix. EXT1 can
route to either or both MIX1 and MIX2. EXT2 can route to MIX2 only.
This would give you a dedicated effects return to each mix, or one
return routed to both. The pre-level signal feeds the monitor source
selector. Use a pointed object such as a pen to select MIX1 and/or
MIX2 routing switches as required.
Monitor Inputs
To return sources to the monitor selector for
monitoring only. With both switches in the up position the signal feeds
the monitor source selector and is not affected by the level control.
This is the case when the input is used for monitoring only and should
not feed the main mix, for example checking a stereo recording or an
off-air broadcast signal. The tamperproof underpanel routing switches
prevent accidental operation. If the switch were accidentally pressed
the signal would route back on itself and cause feedback. Decide the
application of these inputs and set the switches accordingly.
EXT1(2) IN The rotary controls adjust the level of the external inputs
when routed to MIX1 or MIX2 or both as selected on the routing
switches above. Note that these do not affect the feeds to the monitor
selector. Operating level is – 1 0dBV as standard but may be changed to
+4dBu by resoldering an internal link.
