Channel Controls
6 Input channels are provided. Each has switchable inputs for two stereo
sources. CH1-4 provide line and phono (RIAA) inputs. CH5 and 6 feature
valve preamps and have two switchable line sources each. All channels
provide insert points for patching in additional equipment. Internal jumper
options let you change the gain settings and switch out the RIAA equalisation.
Phono / Line select
CH1-4 This toggle switch selects the PHONO input
in its left position, or the LINE input in its right position.
Line A / Line B select
CH5,6 This toggle switch selects the LINE A
input in its left position, or the LINE B input in its right position.
RIAA
The PHONO input passes through an RIAA equaliser. This
compensates for the response of the turntable pickup cartridge and results in
the desired flat frequency response. Note that the RIAA equaliser can be
bypassed using internal option jumpers if you want to use the inputs for
additional line sources instead.
Valve preamps
The CH5 and CH6 preamps provide the warm, musical
sound associated with the characteristically strong second harmonic distortion
associated with the valve circuit.
Meter
This has 8 LEDs which display the level from -18dB to +10dB relative
to the normal 0dB operating level. It is peak responding so that it can
accurately display fast music peaks. The stereo L and R signals are summed
to feed the meter display. Turn back the LEVEL control if the red ‘+10’ LED
lights. Although there is still plenty of headroom above this level, it is important
to prevent very high channel levels which could overload the mix if several
sources are being mixed together.
