- 7 -

(15) Mode - A three-position switch which sets the compression section into either Bypass mode

(BYP), Compression (COMP), or Limiting (LIMIT). When the switch is in the COMP position, the degree

of compression is gentler and at a low ratio (approximately 3:1, program-dependent). When the switch

is set to the LIMIT position, there is more severe compression, and at a higher ratio (up to ∞:1,

again, program-dependent). ( see pages 18 - 22 for more information)

(16) Meter - A standard VU meter that displays either the preamp section output, amount of gain

reduction, or final output level, depending upon the setting of the Meter Function switch.

( see #14 on page 6) ( see page 25 for instructions for calibrating the LA-610 meter)

(17) Power - Turns the LA-610 power on or off. When powered on, the jewel light immediately to the

left of this switch is lit.

 The LA-610 Mk II differs dramatically from the original LA-610 when the unit is in Bypass

mode (BYP). With the original, even when the LA-610 was set to BYPASS mode, incoming

signal continued to pass through the compressor section. For that reason, the compressor

Gain control remained active. The LA-610 Mk II has true bypass, which completely removes

the T4 Optical Compressor section, including its makeup gain control and GR/COMP

metering.

 The LA-610 Mk II uses a larger, and better-lit, easier to read meter than its predecessor.

The meter is lit with LEDs, so no bulb will ever need replacing. The improved meter

electronics means a highly stable meter with no drift.

 Unlike the original LA-610, the LA-610 Mk II uses an LED to illuminate the power jewel light.

Therefore, no bulb will ever need replacing.

 The audible difference between compression and limiting on the T4 compressor can be quite

subtle. Greater audible differences are more easily detected on transient-rich sources, and

when a large amount of gain reduction is applied.

 The LA-610Mk II gives the user 15 dB of additional gain above other 610 products through

the makeup gain of the T4 compressor (a total of 77 dB). Turn off Peak Reduction for when

maximum gain is needed such as with low-output ribbon microphones.
